Introduction:When the earliest ancestors of the Filipino people first set foot on this tropical archipelago, they must have instantly marveled at sharing such a vibrant paradise with countless living creatures. Walking through what was then a pristine tropical eden, they entered a breathtaking world filled with towering trees, lush foliage, and a kaleidoscope of multi-colored wild flowers.The air was alive with the melodious songs of birds, while teeming life hid within every thicket and beneath the surface of every pond and stream. Within nature’s grand design, they quickly realized that few places on Earth were as richly endowed with life as the Philippine forests.
Key Highlights of Philippine Mammalian Life
High Endemism: A vast portion of this wildlife consists of mammals, the majority of which are exclusively native (endemic) to the Philippines.
Widespread Distribution: Almost any island spanning at least one hectare with sufficient vegetation and mixed trees is home to some species of mammals.
Remarkable Resilience: Even tiny islets under half a hectare with tree cover frequently support their own resident mammal populations—such as large fruit bats and flying foxes that use them for daytime roosts.
Terrestrial Dominance: Out of more than 233 recorded species and subspecies of Philippine mammals, roughly 99% are land-dwelling, with the remainder being aquatic and marine species.
Our Shared Responsibility
This website highlights many of these fascinating and rare Philippine mammals. The goal is to raise awareness among Filipinos about their existence and ecological importance, deepen our understanding of their natural habits, and inspire conservation efforts so these treasures can be preserved for future generations.
( Bubalus mindorensis ) Heude 1888
- Coat and Build: It features a thick, robust body covered in dense, dark brown to brownish-black hair—noticeably thicker than that of a domesticated carabao—alongside short, stout limbs.
- Horns: Its short, heavy horns are triangular at the base and marked by very distinct, rough ridges and grooves.
The distal parts taper into sharp, pointed tips that curve inward and come close together. - Head and Temperament: The front of its skull is slightly bulging, and it possesses moderate-sized ears featuring characteristic white markings on the inner side.
Famed for its tenacity, this dwarf buffalo is notoriously fierce and defensive when cornered, with historical accounts from local hunters warning that it will readily attack even when slightly wounded and best to have nearby tree to climb when hunting a Tamaraw.
Habitat, Range, and Migration
- Preferred Terrain: They frequent dense riparian vegetation along lowland rivers, marshy swamplands, open tropical grasslands, and secondary successional forests, ranging from sea level up to high mountain ridges exceeding 2,000 meters.
- Migration Paths: Populations residing in the lower slopes and valleys of peaks like Mount Halcon regularly migrate across lower mountain ranges. They follow precise, narrow, and circuitous trails carefully chosen for gentle slopes, winding across ridges and down into forested valleys interspersed with natural open clearings and brooks.
Behavior and Diet
- Social Structure: Unlike many herd-dwelling bovids, adult tamaraws are predominantly solitary.
They typically roam alone, though temporary pairs form during breeding seasons, and small family clusters of 4 to 7 individuals are occasionally spotted while feeding. - Diet: They are strict herbivores (graminivores) that graze heavily on coarse grasses like cogon and talahib, alongside young bamboo shoots and wild sugarcane.
They are also known to visit newly burned agricultural patches to feed on fresh, nutrient-rich grass shoots. - Reproduction: Cow tamaraws typically give birth to a single calf every two years. Calves start out with a lighter reddish-brown coat and gradually transition to the dark adult coloration around 3 to 4 years of age, achieving independence shortly thereafter.
Conservation Status and Threats
- Current Status: Classified as Critically Endangered on the IUCN Red List, only a few hundred individuals remain confined to isolated strongholds on Mindoro.
- Core Sanctuary: To protect the species from poaching, illegal hunting, and severe habitat loss driven by human settlement and slash-and-burn farming, the Philippine government established key conservation zones—most notably the Mounts Iglit-Baco National Park, which serves as the primary scientific study and protection area for the survival of the species.
(Tragulus nigricans) Thomas 1892
The Balabac mouse-deer (Tragulus nigricans), locally known as the pilandok or Balabac chevrotain, is an exceptionally small, hornless ruminant.
Size: Dainty and remarkably diminutive, it stands only about 18 cm (7 inches) tall at the shoulders, with a head-and-body length measuring roughly 40 cm to 50 cm (15 to 20 inches).
Dentition: Both sexes lack horns or antlers.
Instead, they possess functional canines in both jaws, with those in the upper jaw of males being exceptionally well-developed into prominent, tusk-like fangs used for territorial defense. Coat and Markings: Its general coloration features a rich brown upper body washed with jet-black hair tips and white bases.
The face and sides of the neck display a mixed pattern of black and fulvous fur. A signature feature of the throat includes a starkly defined pattern: a naked glandular patch on the chin, framed by crisp white throat stripes separated by deep, jet-black bands. The inner thighs and lower belly feature lighter or white-washed patches.
Behavior, Habitat, and Ecology
Endemic exclusively to Balabac Island and a few adjacent small islands (such as Bugsuk and Ramos) southwest of Palawan, the pilandok leads a highly secretive, nocturnal life.
Daytime Habits: During daylight hours, it remains hidden deep within the dense vegetation and heavily shaded spots of primary virgin forests or adjacent secondary-growth forests.
Night Activity: Under the cover of darkness, it roams out into open clearings, sometimes venturing dangerously close to the seashore. When caught in a flashlight beam at night, its eyes flash brightly, and the animal typically freezes, staring fixedly for a short duration before darting away.
Diet: As a strict herbivore, it feeds mainly on fallen forest fruits, tender leaves, buds, young shoots, and wild berries (such as those from the tubog tree).
Social Structure and Reproduction: Mouse-deer are characteristically solitary, coming together only in temporary pairs during the mating season.
A mating pair usually yields a single offspring per breeding season, with a gestation period lasting roughly 140 to 177 days.
Conservation Status and Human Interaction
Local Utilization: Historically, the meat of the Balabac mouse-deer has been prized as a localized delicacy by island inhabitants, while its soft hide has occasionally been utilized by locals for leather.
Threats and Status: Due to habitat loss from agricultural clearing and localized hunting pressure, the species faces severe survival challenges and is currently classified as Endangered. Protecting its remaining fragmented woodland habitats on Balabac is crucial to ensuring this unique living treasure survives for future generations.
The Visayan Leopard Cat (Prionailurus javanensis sumatranus, formerly grouped under Prionailurus bengalensis rabori) is a small wild cat that is roughly equal to or slightly smaller than an average domestic cat.
Size and Proportions: It has a body length ranging from 16 to 18 inches (0.41 to 0.46 meters), paired with a short tail averaging 7 to 9 inches (0.18 to 0.24 meters). Compared to domestic cats, it features relatively short ears that are rounded at the tips and set further apart from the eyes.
Coat and Markings: The upperparts are a rich golden-brown, patterned with spots and stripes of darker brown, while the flanks are lighter than the back. The underparts are white or grayish-white, distinctly spotted with blackish-brown.
Facial and Tail Details: Distinct facial features include a brown stripe running down the nose to the forehead (bordered by short whitish lines), a short stripe below each eye, and another clear brown stripe originating from the inner eye corner running toward the nose before angling down toward the upper lip. The chin is pure white. Its tail features spots only near the base, with the greater part brown and fading to a silvery-white tip, while the lower parts of its hind legs remain unspotted in brown or gray-brown.
Habitat, Behavior, and Ecological Role
Historically forest-dwellers, these small cats have adapted well to environments where extensive lowland forests have been cleared for agriculture.
Agricultural Strongholds: Under current conditions, they frequently prefer to stay inside dense vegetation areas such as ripening sugarcane fields, cornfields, and rice fields. For instance, a young male recorded near the Amio River in Southern Negros was found with a stomach full of fresh field rats.
Natural Pest Control: Active primarily at night (nocturnal), a typical family uses a home range of about 4 to 5 hectares of ripening sugarcane.
Because a pair and their usual litter of three kittens depend heavily on local rodents, these cats act as an essential biological control agent. Thanks to their presence on Panay and Negros, severe rat infestations on sugarcane and rice crops have historically been minimized. Vocalizations and Habits: During the mating season, the male (tom) emits a much harsher call to its mate compared to domestic cats. As the kittens grow older, they join the parents in hunting, learning to catch rats to sustain the family unit.
Taxonomy, Distribution, and Conservation Status
Taxonomic History: Formerly classified under the genus Felis (as Felis minuta) and later categorized under Prionailurus, modern taxonomists recognize it as part of the broader Sunda leopard cat species complex found across Southeast Asia.
A related subspecies, Prionailurus bengalensis heaneyi, is found on Palawan, though it possesses a paler coat than the Visayan counterpart. Current Distribution: P. j. rabori is rare and restricted primarily to the islands of Negros and Panay.
Due to severe habitat destruction and historical land clearing, it is believed to be locally extinct on Cebu. Threats: Despite acting as 100% rat predators that benefit local farmers, these small cats face heavy hunting pressures as they are frequently killed by locals for bushmeat. Combined with rampant deforestation and agricultural shifts, the subspecies is categorized as Vulnerable on the IUCN Red List, with remaining populations fighting for survival in fragmented forest remnants and protected locations like the Mari-it Wildlife and Conservation Park.
Local Name : Mamag, Mawumag, Malmag, Mago (Bis.)
Size and Proportions: Its body is remarkably small—even smaller than a large rat—with a head and body length shorter than its long, slender tail. The tail is mostly naked, save for a few tufts of hair at the tip, and is dark brown in color.
Coloration: The fur covering its entire body is predominantly a rich reddish-brown, particularly on the upper parts, head, and outer limbs. The throat and chest feature a brighter reddish hue that contrasts with the yellowish-gray underparts.
Enormous Eyes: Its rounded head houses its most striking feature: an immense pair of fixed, forward-facing eyes adapted for specialized night vision. If human eyes were proportionately as large, they would be the size of medium-sized oranges. Because its eyes cannot move in their sockets, tarsiers make up for it by possessing the unique ability to swivel their heads 180 degrees to the left or right.
Elongated Ankles and Leaping Power: True to its name, the tarsier features two greatly elongated tarsal (ankle) bones in its feet. These elongated bones provide an immense and powerful source of leverage, allowing this rat-sized animal to effortlessly clear a distance of 4 to 6 feet in a single jump.
The Philippine tarsier is primarily nocturnal and crepuscular, transitioning between terrestrial and arboreal habits.
Daytime Habits: During daylight hours, it sleeps in dark, deeply shaded spots, clinging vertically to the branches of low trees and dense bushes among thick foliage. When disturbed, it executes rapid leaps from branch to branch, consistently seeking out deep cover.
Where it Lives: It inhabits the edges and interiors of various dense vegetation types, occasionally venturing into thick bushes growing at the edges of abandoned cogonal grasslands.
Diet: As a strict carnivore and insectivore, its primary diet consists of large grasshoppers, beetles, and other insects. It is also known to supplement its meals with small lizards and small snakes, catching prey with swift, agile hand-eye coordination.
Geographic Range and Conservation Status
Distribution: The Philippine tarsier is rare and restricted to specific islands in the southern and central Philippines, most famously Bohol, as well as neighboring islands like Samar, Leyte, and parts of Mindanao.
Legal Protection: Due to historical pressures from the pet trade, habitat fragmentation, and stress-induced mortality in captivity, capturing, collecting, or harming the Philippine tarsier is strictly prohibited under Philippine wildlife protection laws (such as Republic Act No. 9147). Dedicated sanctuaries, particularly in Bohol, continue to protect its dwindling secondary forest habitats.
( C(CLICK PHOTO TO SEE VIDEO RELATED TO TANGALONG CIVET)
Size and Proportions: It measures roughly 0.90 to 1 meter (approx. 3 feet) in total length with a shoulder height of about 0.38 meters (15 inches). Its elongate body is supported by short legs equipped with long, non-retractile claws, and its tail spans less than half of its combined head-and-body length.
Coat and Crest: The fur is long, loose, and coarse. When the animal is excited or threatened, the long hairs along the dorsal median line stand on end, forming a low, bristly crest.
Distinctive Markings:
Head and Face: The snout is naked and truncated, framed by long facial vibrissae (whiskers) that can reach the tips of the ears. The face is grizzled, with eyes distinctly margined in black and lighter markings around the mouth and above the eyes.
Neck Stripes: The sides of the neck feature three striking black lines separated by contrasting whitish-to-grayish interspaces. The uppermost line extends toward the foreleg, while the two lower lines cross the throat to join their counterparts from the opposite side.
Body and Tail: The flanks are heavily mottled and reticulated with varied dark spots and blotches. The tail is marked by black rings with lighter alternating bands below. A defining characteristic is the patch of brilliant reddish-brown hair surrounding the anal/perineal region, which contrasts sharply with the surrounding fur. Overall coat patterns vary remarkably across different specimens found throughout the archipelago.
Habitat, Behavior, and Diet
The Tangalong civet is adaptable and widely distributed across various lowland environments.
Where it Lives: It inhabits the edges of both primary and secondary forests, parang (grasslands mixed with forest vegetation), and well-cultivated agricultural lands close to human settlements, especially farms situated near forest patches.
Nocturnal Habits: Primarily active at night (nocturnal), it follows regular, established trails while foraging. It possesses the unique habit of repeatedly depositing its dung in designated communal spots (latrines) along these pathways. Unlike some arboreal viverrids, it is primarily terrestrial and rarely observed climbing trees.
Diet: It is an opportunistic omnivore. Its natural diet consists heavily of forest fruits (such as wild figs and bananas), supplemented by small animals like birds, mice, and rats. When natural prey is scarce, it occasionally ventures near rural homes to prey on small poultry chicks, though local fears regarding its impact on livestock are often exaggerated.
Geographic Range: In the Philippines, it is distributed across most of the major islands. Regionally, it is also widespread throughout Southeast Asia, including the Malay Peninsula, Borneo, Sumatra, Sulawesi, and neighboring islands.
Historical and Commercial Uses:
Fur and Pelt: Historically, its pelt has been utilized locally to craft unique caps with the tail hanging down (resembling a traditional frontier cap). It has also been explored as a candidate for stock farming to yield fur for coats and jackets.
Civet Secretions: Its perineal glands produce a strong-smelling musk called "civet," which was once a prized fixative base in global perfume manufacturing before being largely replaced by synthetic alternatives.
Bushmeat and Persecution: Rural communities frequently hunt the Tangalong civet for its meat, driven partly by the belief that it threatens backyard poultry.
Current Status: Due to ongoing habitat fragmentation, conversion of agricultural lands, and sustained hunting pressure, sightings in the wild have decreased, prompting local restrictions on hunting to safeguard remaining populations.
( Rusa mariannus) Desmarest 1822
Size and Proportions: It measures roughly 4 feet and 8 inches in total body length, with a shoulder height averaging around 2 feet and 6 inches.
Coat and Markings: Its fur is harsh and of moderate length. The upperparts exhibit a rich reddish-brown coloration, growing darkest along the neck, while the forehead and cheeks feature a lighter reddish-fawn tone. Distinct blackish streaks originate above each eye and merge into a center facial band, separated from a dark moustache-like mark bordering the muzzle by a narrow strip of pale fawn. The breast and belly are a uniform brown, and a distinct red spot marks the tarsal gland.
Antlers and Senses: The male's horns (antlers) are massive, heavily ridged, and feature a strong, long brow antler alongside a short inward-directed tine. Its ears are moderate in size, with the external surface covered in short, close-set hair.
The Philippine brown deer is naturally bound to forest environments, though it shows remarkable adaptability to adjacent ecosystems.
Where it Lives: It inhabits interior regions covered by dense original forests—including lowland dipterocarp forests and mid-mountain forests—ranging up to 1,500 meters above sea level in transition zones toward mossy forests. It also frequents grassland edges, retreating instantly into dense woodland cover when disturbed.
Mineral Seeking (Ash Licking): Following traditional kaingin (slash-and-burn) clearing, when thick layers of plant ash coat the ground, these deer are strongly drawn to lick the ashes to satisfy their biological salt and mineral requirements. Hunters historically exploited this habit by burning large cogonal grass areas to lure them.
Feeding Habits and Night Activity: They are primarily nocturnal or crepuscular, feeding more actively at night. Weeks after a burn, fresh, nutrient-rich shoots of cogon grass sprout from the soil, attracting large numbers of feeding deer.
Rutting and Mating: The breeding season aligns with the dry months in the Philippines, typically running from February to May. During the rut, stags broadcast their presence from prominent vantage points using a distinct dog-like barking sound to attract potential mates—a vocalization easily mistaken from a distance for a domestic dog. Stags grow their first set of velvet-covered antlers after completing their first year of life.
Geographic Range and Historical Introductions
Native Distribution: The Philippine brown deer is exclusively endemic to the Philippines. Historically, it thrived across dense forest strongholds in Luzon, Mindoro, Polillo, Catanduanes, Samar, and Leyte, with distinct subspecies found in Mindanao. However, populations are likely extirpated or extinct on islands like Cebu, Marinduque, and Bohol due to historical pressures.
Global Introductions: Interestingly, during the Spanish colonial era (between the 18th and 19th centuries), specimens were successfully introduced to Guam and the Mariana Islands, where descendant populations still roam today.
Culinary and Hunting Pressure: Highly prized for its delicious meat (venison), the species was historically subjected to rampant, uncontrolled spotlight hunting. Hunters using headlamps or flashlights would spot the glowing eye-shine of deer feeding on newly sprouted cogon patches at night, with single hunters capable of bagging multiple animals in a single outing.
Threats and Protection: Combined with the ruthless destruction and fragmentation of its natural forest habitats, overhunting has drastically depleted wild populations. Consequently, the Philippine brown deer is classified as a Vulnerable to Endangered species and receives strict legal protection under Philippine wildlife conservation laws.
( Hystrix pumila) Gunther 1879
Size and Proportions: It measures between 20 inches and 2 feet in total body length, supported by limbs of roughly equal length and a short tail.
Quills and Spines: The greater part of its body is densely covered in flattened, deeply grooved, and somewhat flexible spines. Moving toward the posterior half of the body and the rump, these spines transform into nearly rigid, strong-grooved quills that taper down toward the tail. At the tip of the tail are unique bristles ending in small capsule-like cups (open or closed) with long bristle tips, alongside a few long, stiffened vibrissae.
Specialized Features and Coloration: Prominent tufts of very long vibrissae emerge below the front base of the ears, while its nose is covered in fine, short hairs and its feet are clad in rough, bristle-like hair. Its prominent upper and lower incisors feature bright orange outer surfaces. The coloration varies from dark drab brown with dirty whitish bases and tips on the anterior spines, to nearly black-tipped markings on the rear quills, a flecked appearance on the sides, and a lighter mix of buff-white on the underparts and breast.
Endemic exclusively to Palawan and Busuanga islands in the Philippines, this species leads a secretive life.
Nocturnal Habits: The Palawan porcupine is strictly nocturnal, spending daylight hours hidden inside deep burrows, rock crevices, or hollow logs before emerging at night to forage.
Clearing and Foraging: It frequently frequents forest clearings, particularly those located near the edges of dense original lowland forests and standing woodland remnants.
Diet and Agricultural Impact: It feeds largely on roots, tubers, bark, and juicy plants. Occasionally, its foraging habits lead it to raid agricultural areas, where it can cause damage to coconut trees by chewing through husks or roots.
Fascinating Defense Strategy: When disturbed or cornered, the porcupine initiates a distinct warning display: it shakes its tail, causing the hollow-tipped quills to rattle together to produce a hissing, rattling sound strikingly reminiscent of an aroused rattlesnake. If this auditory warning fails to deter an intruder, it turns around, presents its rear end, and walks backward toward the threat before executing a sudden burst of speed to drive its sharp, detachable quills into the attacker.
Culinary Value: The meat of the Palawan porcupine is considered tender and delicious by local inhabitants, with a taste often compared to pork.
Threats and Legal Protection: Due to sustained hunting for bushmeat and ongoing habitat loss from agricultural clearing, the Palawan porcupine has become increasingly uncommon and scarce in the wild. Consequently, hunting, capturing, or trading this unique endemic rodent is strictly restricted and protected under Philippine wildlife conservation laws.
( Macaca fascicularis philippensis) I. Geoffroy 1843
Size and Proportions: It measures roughly 17 to 24 inches in head-and-body length, paired with a long tail that roughly matches its entire body length. It features a heavy, stocky frame supported by relatively short, stout limbs and opposable thumbs (with nails adapted for gripping).
Facial Features and Anatomy: Its head features a long nose (though not extending past the upper lip) with downward-facing nostrils, prominent bony ridges surrounding the eyes, naked and pointed ears, and large cheek pouches for storing food. Males possess long, powerful canine teeth, and both sexes feature large, hairless callosities (calloused patches) on their buttocks.
Coat and Coloration: The upperparts display a mummy brown coloration, with individual hairs ringed in blackish-brown. The top of the head is tinged with a distinct chestnut shade, while the sides of the head are a grizzled yellowish-olive. A signature feature is a row of stiff black hairs across the forehead, separated from the naked eye orbits by a narrow line of short brown hair. The underside, inner limbs, and silky chest hairs are pale drab-gray, contrasting with a brown genital region, grayish-black tail, and outer limbs mixed with gray on the wrists, ankles, hands, and feet.
Habitat, Social Behavior, and Diet
Widely distributed across most major and minor islands of the Philippines, these macaques are highly adaptable.
Elevation and Range: They inhabit diverse environments ranging from coastal mangrove seacoasts up to 1,000 meters in elevation, moving through dense forests and agricultural fringes.
Social Structure: They live in complex social groups (troops or bands) typically numbering 6 to 12 individuals or significantly larger. A dominant, large old male acts as the leader of the troop, guiding mothers and their young.
Human-Like Alarm Systems and Escape Tactics: Macaques exhibit remarkably sophisticated reactions to danger. Upon hearing an alarm call a sharp "Kraa!!!" all feeding instantly halts. The troop freezes or executes furtive flights until completely concealed. Minutes later, they will silently relocate to a new tree roughly a hundred meters away before resuming their noisy social and feeding activities.
Diet and Crop Raiding: Primarily frugivorous, they feed on the fruits of numerous forest tree species. However, when their habitat borders human settlements or agricultural clearings, they frequently raid farms, feeding on valuable crops such as corn, camote (sweet potato), ube, bananas, papayas, and cultivated fruits.
Human Interaction and Conservation Status
Historical and Medical Significance: Historically, the Philippine long-tailed macaque has served as an important biomedical research model. Large numbers of various races were exported to the United States and globally during the 20th century, famously playing a crucial role in the development and safety testing of the Salk polio vaccine. They have also been frequently kept as intelligent companion pets in local communities.
Bushmeat and Trade: In rural areas, macaque meat has traditionally served as a source of bushmeat for local inhabitants.
Current Status and Protection: Due to historical overhunting, live-capture for the international pet and lab trades, and the rapid destruction of Philippine forest habitats, wild populations have experienced significant declines. Consequently, capturing, hunting, or trading the Philippine long-tailed macaque is strictly regulated and protected under Philippine wildlife laws.
PALAWAN STINK BADGER
( CLICK PHOTO TO SEE VIDEO RELATED TO PALAWAN STINK BADGER)
Size and Proportions: It measures roughly 15 to 20 inches in body length, paired with a relatively short tail measuring about 8 to 16 inches (though older texts note variation where the tail hair extends past the tip). It is supported by short, stout legs.
Facial Features: Its head is rather long and pointed, featuring a distinct, truncated, pig-like naked snout with downward-opening nostrils at the anterior end and sparse whiskers (vibrissae). Its eyes are small, and its ears are extremely minute, hardly raised above the surrounding skin.
Coat and Distinctive Markings: The upperparts are uniformly dark brown, with hairs fading to gray toward the base. The underparts, neck, and rear regions mirror this dark brown shade, though the fur around the anal area and rear legs lightens slightly. Its most striking signature feature is a clear, triangular patch of silvery-white on the head and neck, which varies in size and intensity among individuals.
Habitat, Behavior, and Diet
Endemic exclusively to the islands of Palawan and Busuanga in the Philippines, this species shares close taxonomic ties with forms found in Java, Sumatra, Borneo, and the Natuna Islands.
Where it Lives: It inhabits deep forest interiors as well as forest patches interspersed among rural clearings. It is frequently encountered along the banks of rivers and creeks amid mixed vegetation, or when crossing between woodland patches and agricultural clearings.
Movement and Foraging: Not known for speed or agility, the Palawan stink badger moves at a very slow, deliberate pace. As it walks, it frequently dips its head close to the ground, using its acute sense of smell to track direction and locate food.
Diet and Ecological Role: As an insectivore, its primary diet consists of earthworms, grubs, beetles, and ground-dwelling insects. In doing so, it serves a beneficial ecological function by helping control insect pests that threaten local trees and farmers' crops.
Infamous Defense Mechanism: When excited, startled, or threatened, it deploys a classic mephitid defense: it turns its rear toward the intruder, approaches closely, and ejects a highly concentrated, intensely foul-smelling fluid from its well-developed anal glands. This pungent secretion lingers persistently in the air for a long time, effectively deterring predators and onlookers alike.
Current Status: Although considered "surprisingly common" in the 1970s, and despite local concerns regarding habitat loss and roadkill, the official global assessment by the International Union for Conservation of Nature (IUCN) lists it as Least Concern due to its stable overall populations and local adaptability.
Threats and Protection: Like many unique Philippine exotic fauna, its populations are facing declines driven primarily by the ongoing loss of its natural forest habitats. To prevent further population depletion, the Philippine government strictly restricts and protects the hunting, capture, and collection of the Palawan stink badger under wildlife conservation laws.
(Cynocephalus volans) Linnaeus 1758
( CLICK PHOTO TO SEE VIDEO RELATED TO PHILIPPINE COLUGO)
Philippine Colugo
( Cynocephalus volans) Linnaeus 1758
Local Name : Philippine Flying Lemur, Kagwang, Kalago, Kolago, Kago, Gagua, Kabal
The Philippine colugo (Cynocephalus volans), also known locally as the kagwang or Philippine flying lemur, is a remarkable mammal slightly smaller than its counterpart in Borneo.
Size and Proportions: It measures about 25 to 27 inches in total length, which includes a tail spanning roughly 9 inches. It features a characteristic dog-like face, long limbs, and a long tail.
The Gliding Membrane (Patagium): Displaying the highest evolutionary development of gliding adaptation among mammals, it possesses a broad, thin, fur-covered membranous skin (patagium).
This web of skin extends gracefully from the neck to the thumbs, between the fingers, from wrists to ankles, between the toes, and out from the tips of the long outer toes all the way to the tip of the tail. Philippine colugo can glide for more than 100 meters from tree to tree. Pelage and Coloration: Its fur is soft, fine, and furry. The head is typically grayish with a distinct white spot between the eyes, while the back leans more brownish. The upperparts range from dark brown to buff with gray, smoky, or brownish-gray hair tips. The shoulder and rump hairs are tipped with whitish-buff, the belly is a brownish-buff, and the membranes underneath are brown (with the posterior membrane lacking fur). Overall coat colors vary widely among individuals.
Comb-Shaped Teeth (Pectinates)The colugo's lower incisors are completely unique in the mammal world. Instead of solid bone, each tooth features fine, comb-like serrations:- The "Toothcomb" Structure: A single tooth can have up to 20 individual tines or "prongs," making it look exactly like a miniature hair comb.
- Grooming: Colugos use these built-in combs to scrape parasites, dirt, and loose fur out of their coats to maintain health.
Habitat, Behavior, and Ecology
Despite being called a "flying lemur," it does not truly fly or belong to the lemur family;
Gliding Ability: While its membrane does not provide upward motile power, it allows the colugo to execute effortless, sweeping glides across wide gaps in the forest canopy.
Nocturnal Habits and Nesting: The Philippine colugo is strictly nocturnal. It spends daylight hours securely hidden inside natural hollows in the trunks of standing dead trees or within cavities in the branches of live trees.
As darkness falls, it emerges and becomes highly active. Diet: It inhabits lowland and interior forests close to seashores, feeding primarily on young shoots, tender leaves, flower buds, and ripening fruits.
Reproduction: Mirroring the behavior of bats, it typically suspends itself from tree branches. Females give birth to a single young, which clings tightly and securely to the underside of the mother's body while she forages through the canopy and navigates the forest safely.
Unlike typical placental mammals that give birth to relatively well-developed young, a colugo mother gives birth to a tiny, highly underdeveloped baby weighing only about 35 grams. Because the infant cannot survive on its own, the mother creates a quasi-pouch somewhat seemingly marsupial pouch.- The Patagium Shield: She folds her patagium (the expansive skin membrane used for gliding) and curls her tail up against her belly.
- Safe Transport: This creates a warm, secure, hammock-like pouch where the baby clings, nurses, and stays safely tucked away for its first six months of life—even while the mother glides between trees.
True Evolutionary IdentityDespite these marsupial-like parenting habits, the colugo belongs to its own entirely distinct taxonomic order called Dermoptera (which translates to "skin wing").- Primate Cousins: Genetic testing has revealed that colugos are actually the closest living evolutionary relatives to primates (the group containing monkeys, apes, and humans).
Endemic Range: The Philippine colugo is exclusively endemic to the southern and southeastern islands of the Philippines, including Samar, Leyte, Bohol, Mindanao, Dinagat, Siargao, and Basilan. Notably, it does not naturally occur in the northern, western, or central island groups.
Commercial Uses and Protection: In parts of Mindanao, its pelt has historically been utilized to craft novelty caps. When properly prepared, its soft, beautiful fur holds potential as a material for women’s coats and wraps. However, because of localized hunting pressures and ongoing woodland habitat degradation, the Philippine government restricts the hunting and collection of the colugo to protect its wild populations.
PALAWAN BEARDED PIG
(Sus ahoenobarbus) Huet 1888
( Sus ahoenobarbus) Huet 1888
Local Name : Pagil, Babuy-ramu, Babuy
Head and Facial Markings: It features a long, narrow head with a greatly elongated nasal portion. The nose, upper lip, and chin are covered in short black hair. A striking signature feature is a distinct lateral band across the face: a band of very large hairs (blackish at the base and ochraceous/yellowish toward the tip) runs in front of the eye, narrows along the side of the nose, passes under each eye, and then widens to spread across the jaw up to the back angle of the lower jaw (mandible). Just behind the snout and in front of this yellow band are two tufts of harsh bristles that curl or frizz backward (giving it a bearded appearance).
Mane and Coat: The throat, eyes, forehead, crown, body, and limbs are predominantly covered in black hair. Beginning at the top of the head and running down the median line of the neck is a prominent mane formed by longer hairs that feature yellowish tips. From between the shoulders continuing down the back, this mane shifts to entirely solid black hairs.
Tail and Ears: The tail is quite large, featuring long black hairs along the median line that grow much longer toward the tip, culminating in a flattened brush-like end. Its small ears terminate in distinct points and are covered in black hair above while remaining nearly naked below. Females share a similar overall coloration to males with only slight variations.
Habitat, Behavior, and Diet
Endemic exclusively to the Palawan faunal region, these wild pigs are adapted to a mix of forest and agricultural habitats.
Where it Lives: The Palawan bearded pig inhabits both original primary forests and secondary growth forests, as well as dense brushlands and parang (grassland-forest mosaics).
Nocturnal Habits: Primarily nocturnal in behavior, they spend daylight hours resting in hidden cover. They are usually only encountered in the deep forest when accidentally flushed or disturbed from their daytime resting beds.
Diet and Crop Impact: Their natural diet consists heavily of fallen forest fruits, particularly wild figs, roots, and tubers. However, when forests border agricultural clearings, they frequently raid farms, feeding on valuable human crops such as corn, camote (sweet potato), ube, gabi (taro), and occasionally ripening rice fields, where large numbers can cause extensive agricultural damage.
Geographic Range and Conservation Status
Native Range: The Palawan bearded pig is found exclusively in the Palawan island group, including Palawan, Busuanga, Culion, Coron, and Balabac. It does not naturally occur on the main Philippine islands further north or east.
Human Use and Threats: Due to its massive size, it has historically served as a prime, highly valued source of bushmeat for local communities.
Conservation Status: Because of intensive hunting pressures for its meat, retaliatory culling due to crop raiding, and the accelerating destruction and fragmentation of its forest habitats, wild populations have experienced sharp declines. Consequently, the Palawan bearded pig is classified as a Vulnerable species and receives legal protection under Philippine wildlife legislation (such as Republic Act No. 9147) to prevent its extinction.

Dugong
( Dugong dugon) Muller 1776
Local Name : Dugong, Duyong
Distinct Anatomy: Unlike whales, the dugong lacks a dorsal fin, features nostrils that are invariably separated, possesses a smooth crescent-shaped tail expanded into broad flukes, and has its two mammary glands (nipples) situated on either side right behind the forelimbs (flippers) rather than near the anus.
Snout and Bristles: Its broad, obtuse snout features a unique vertical median anterior groove accompanied by paired vertical lateral grooves—a structure unlike any whale. The front of its mouth and lower lip are lined with thick, short bristles, while its skin is smooth and sparsely dotted with inconspicuous short bristles.
Teaches and Tusks: Adult males possess enlarged upper incisors that form prominent tusks, whereas females have much smaller tusks that do not pierce the gum. Their cheek teeth continuously erupt from the back of the jaw, pushing older worn teeth forward to replace them.
Coloration: The general color of the upperparts is a uniform bluish-gray to grayish-brown, fading to a lighter whitish-gray on the underparts.
Habitat, Behavior, and Sensory Adaptations
The dugong is the only completely marine mammal that is strictly herbivorous.
Diet and Foraging: Primarily active and feeding at night, it grazes on underwater meadows of green "dugong grasses" (seagrasses) and green seaweeds. It possesses a remarkably keen sense of taste, allowing it to selectively choose green seaweeds while rejecting brown ones, aided by an acute sense of touch in its highly prehensile lips.
Social Habits: Dugongs are rarely seen congregating in large herds, typically traveling alone or in small, loose mother-calf pairs. They emit a strong, distinct species-specific odor.
Senses:
Vision: Their vision is rather poor; their eyes are deeply sunken on either side of the head, restricting their field of view mostly forward and downward.
Hearing: Their sense of hearing, however, is exceptionally acute. When beached in the open air, they wince at squeaking sounds, and while in the water, they are easily startled by sudden noises.
Respiration: They surface to breathe, producing a distinct, audible "buff" sound. Normal dives last between 5 to 10 minutes, though breathing intervals can range from every 2 minutes down to just 14 seconds when excited. Surfacing is rapid: they open their nostrils, exhale and inhale quickly, close their nostrils, and submerge back toward the sea floor.
Geographic Range and Conservation Status
Distribution: Dugongs inhabit shallow coastal waters across the Pacific and Indian Oceans, including the South China Sea. In the Philippines, they occasionally migrate through protected inter-island seas and shallow coastal channels, though their presence in certain local areas is sometimes sporadic.
Human Interaction and Threats: Historically valued as an exceptional source of protein and meat, dugong populations have faced severe global and local pressure.
The animals have inspired ancient sailors legends about mermaids. When a female dugong nurses her young, she sticks her head out of the water and holds the calf with her flippers. From a distance, the dugong looks like a woman breastfeeding a baby, according to a report in Science and Technology Daily.
Conservation Status: Today, experts classify the dugong as Vulnerable to Endangered and continuously declining across its range. In the Philippines, dugongs are fully protected under national wildlife legislation, making it unlawful to hunt, kill, capture, or collect them.
PHILIPPINE PYGMY SQUIRREL
(Exilisciurus concinnus) Thomas 1888
( CLICK PHOTO TO SEE VIDEO RELATED TO PHILIPPINE PYGMY SQUIRREL)
Philippine Pygmy Squirrel
( Exilisciurus concinnus) Thomas 1888
Local Name : Laksoy, Buot, Kagsi, Mindanao Pygmy Squirrel
Size and Proportions: While definitively larger than a standard house mouse, it is roughly comparable in body size to a small rat. It features a moderately long, flattened tail, short and soft fur entirely devoid of spines, four well-developed digits on the forefeet (along with a vestigial thumb/pollex), and strong, fully developed toes on the hind feet.
Coloration: The upperparts display a rich dark reddish-brown hue heavily intermixed with black markings. Underneath, the underfur is slate-black, with the terminal half of individual hairs ringed in black and brownish-orange and tipped with black. The cheeks and sides are a muted buff with subtle reddish tones, while the upperpart underfur features a deep neutral gray. Its hands and feet mirror the back's coloration but appear brighter and more reddish. The tail mixes black and brown above and below, growing darker and more intensely black toward the tip.
Habitat, Behavior, and Diet
Endemic exclusively to the southern and eastern islands of the Philippines—including Mindanao, Basilan, Dinagat, Siargao, Samar, Leyte, and Bohol—this specialized squirrel is a master of the vertical forest canopy.
Canopy Climbing: True to its forest-dwelling nature, it frequently scales towering trees, often spotted high up on the straight, massive trunks of dipterocarp trees. Because of the immense height, it takes a considerable amount of time for a tiny pygmy squirrel to journey from the forest floor up to the canopy branches 30 to 35 meters (approx. 100 feet) in the air.
Camouflage and Observation: Field observations in the dense forests of Mindanao and Samar reveal that while one or two squirrels may be actively scaling a trunk, they are notoriously difficult to spot from the ground due to their minuscule size and the thick, dense network of vines, moss, and climbers clinging to the bark.
Specialized Diet: Unlike nut-eating squirrels, its diet is uniquely tailored to the micro-ecosystems found on tree bark. It feeds primarily on fresh mosses growing on tree bark, as well as insect larvae and small insects that inhabit those damp mossy layers.
Ecological Importance and Conservation Status
Natural Pest Control: By foraging extensively on bark-dwelling insects and larvae, the Philippine pygmy squirrel plays a valuable ecological role in keeping insect populations in check—including species that can damage vital forest trees or act as vectors for diseases affecting humans and domestic animals.
Current Status: While they are difficult to collect or study due to their secretive canopy habits and elusiveness, Philippine pygmy squirrels remain fairly common and abundant in localized areas that still retain healthy, undisturbed stands of dense dipterocarp forests.
PALAWAN COLLARED MONGOOSE
(Urvus semitorquata parva) Veron et al (2015
( CLICK PHOTO TO SEE VIDEO RELATED TO SHORT-TAILED MONGOOSE)
Palawan Collared Mongoose
( Urva semitorquata parva) Veron et al 2015
Local Name : Mangangahas, Water Mongoose
Size and Proportions: It measures roughly 1.5 feet in total length, with its tail accounting for about 11 inches of that measurement. It features an elongate, low-slung body supported by short legs. Each foot possesses five toes, with the first toe being short, free, and slightly palmated (webbed)—an adaptation linked to its semi-aquatic lifestyle. The palms and distal soles are generally naked, while the lower parts of the tarsus and metatarsus are typically covered in hair (though variation exists).
Head and Facial Structure: Its head and ears share a general resemblance to other civets and mongooses, featuring a short, compressed face with a broad, arched frontal region.
Coloration: The upperparts display a yellowish-red hue heavily intermixed with black. The head averages much paler and grayer than the body. Individual dorsal hairs are reddish-brown, banded with black, and tipped with yellow (with the dark bands visible at the surface). The underparts are reddish-brown with short yellow-tipped hairs, the forelegs are dusky, and the hind legs match the brownish-red tones of the back and sides, ending in a brownish-black tail. Crucially, unlike true civets, this mongoose lacks scent glands.
Habitat, Behavior, and Specialized Diet
Unlike many other mongooses that prefer dry terrain, the Palawan collared mongoose is semi-aquatic in habit.
Where it Lives: It is closely tied to freshwater ecosystems, typically found near bodies of water such as slow-moving rivers, streams, and flooded forest floors.
Semi-Aquatic Diet: True to its physical adaptations, it feeds heavily on aquatic and semi-aquatic animals, including freshwater fish, crabs, and crustaceans. It is also an adept hunter of both venomous and non-venomous snakes, showcasing the legendary reptilian combat agility common to mongooses.
Geographic Range: This specific subspecies is strictly endemic to the Palawan faunal region, found exclusively on Palawan Island and nearby Calamianes Islands (most notably Busuanga).
Classification and History
- Name Change: Scientists previously grouped the Palawan mongoose with the short-tailed mongoose.
- DNA Evidence: Modern genetic testing showed it actually belongs to the collared mongoose (Urva semitorquata) family as a distinct regional subspecies.
- Rarity: Very few museum specimens or live sightings exist, making it an elusive animal to study.
- Reclassification: Previous scientific consensus grouped the Philippine mongoose population on Palawan with the short-tailed mongoose (Urva brachyura).
- Genetic Evidence: DNA and morphological analysis showed that Palawan specimens cluster closely with the collared mongoose instead.
- Origin: Researchers concluded that the Palawan and Calamian Island populations likely originated from ancestral stock in Borneo
Human Interaction and Conservation Status
Local Utilization: In rural areas where they occur, their meat is occasionally consumed as a source of local bushmeat by inhabitants.
Population Status and Protection: The current population status of the Palawan collared mongoose remains poorly known, and encountering one in the wild is rare. Because of data deficiencies, potential habitat contraction, and localized hunting pressures, catching, collecting, or hunting this unique semi-aquatic mongoose is restricted by the Philippine government under wildlife protection laws to prevent further population declines.
PHILIPPINE SLOW LORIS
(Nycticebus menagensis) Lydekker, 1893
( CLICK PHOTO TO SEE VIDEO RELATED TO PHILIPPINE SLOW LORIS)
Philippine Slow Loris
(Nycticebus menagensis) Lydekker 1893 Local Name : Kokang, Kokam, Bornean Slow Loris
Size and Body Structure: It possesses a rather heavy, stocky body with a rounded head, a short muzzle, and a short neck that makes the head appear as though it is set directly onto the shoulders. Its limbs are short and well-developed, with flat nails on the hands. Its hind legs feature feet turned sharply inward, giving the animal a distinctively bow-legged appearance.
Coat and Coloration: The general color is a light rufous. Individual hairs are dark at the base, transition to gray, and end in light rufous with very short gray tips. The fur on the upperparts, arms, and legs is thick and soft, forming a fine pelt, while the under-surface fur is thinner and lighter. The region around the genitals is a pale buffy-white.
Facial Markings: Its most striking facial feature involves dark rufous patches around the eyes that extend upward onto the forehead. This pattern forms a distinct heart-shaped mask on the face, where the eyes occupy the two lobes separated by a central white mark that ascends toward the point of the heart on the forehead.
Habitat, Behavior, and Unique Adaptations
The Philippine slow loris leads a secretive, arboreal, and strictly nocturnal life.
Daytime Resting Habits: During the day, it sleeps rolled up tightly into a compact ball of fur, with its head tucked securely between its thighs. It moves with deliberate, slow caution along the upper and lower surfaces of small branches and vines, though it is capable of moving backward just as rapidly as it moves forward.
Behavioral Quirks: When confronted or observed closely, it has a peculiar habit of folding its hands over its eyes, shielding its face as if "ashamed" to look directly at an intruder. Occasionally, individuals are spotted foraging in low plants or bushes near rural farmhouses on the outskirts of villages.
Diet: As an opportunistic omnivore, its diet consists primarily of insects, tree sap, nectar, wild fruits, and berries, playing a dual role in insect population control and seed dispersal.
The Rare Venomous Defense: One of the most extraordinary characteristics of the slow loris is that its bite is toxic—a remarkably rare trait among mammals. The toxin is produced by a brachial gland on its upper arm, which the loris licks, mixing the secretion with its saliva to activate it. This venomous bite serves as a powerful defense against predators, and mothers also apply the toxin to their fur during grooming to protect their vulnerable young.
Geographic Range and Conservation Status
Restricted Range in the Philippines: Unlike other Philippine mammals found across multiple major islands, the Philippine slow loris is restricted exclusively to the southern half of the Sulu Archipelago, ranging from Tawi-Tawi Island south to Sibutu. Related species of slow lorises are widely distributed across South and Southeast Asia, including India, Thailand, Malaysia, Sumatra, Java, and Borneo.
Threats and Legal Protection: Though occasionally targeted for the illegal pet trade due to its docile-seeming appearance, keeping or domesticating them is hazardous due to their toxic bite. Due to severe habitat destruction and historical collection pressures, they are rarely seen in their natural habitat today. Consequently, the Philippine government strictly restricts the hunting, collection, and trading of the Philippine slow loris under national wildlife conservation laws.
(Phloeomys pallidus) Nehring 1890
Northern Luzon Giant Cloud Rat
(Phloeomys pallidus) Nehring 1890
Local Name : Northern Luzon Slender-tailed Giant Cloud Rat, Yutyut, Buut, Letlet
Size and Proportions: It measures roughly 15 inches in body length, paired with a long, heavily furred tail measuring about 12 inches (roughly a foot long, making it slightly shorter than the combined head and body).
Head and Ears: It features short ears that are naked on the inside, with long, scattered hairs extending past the tip for about a third of their length. Its long facial vibrissae (whiskers) are exceptionally long, with the longest hairs reaching back to the ears. A distinct characteristic is the fur on the top of the head and forehead, which naturally stands erect to form a prominent crest.
Coat and Distinctive Coloration:
Head and Crest: The crest on the forehead and crown features a grizzled white distal half and a grayish base. The ears are black and covered in black hairs, the cheeks are gray with gray or black tips, and the eyes are margined with black, matching the tip of the muzzle.
Body and Tail: The anterior region of the body features fur with black terminal thirds and grayish to grayish-brown basal two-thirds. The remaining back, sides, and forelimbs feature longer hairs with white distal thirds. The hind limbs and belly shift to a rich reddish-brown on the shorter hairs and basal sections. The tail is densely covered in deep black to brownish-black hair, with only a few gray hairs near the base (the hair is shorter than the body fur, revealing the underlying scale rings or annuli).
Habitat, Behavior, and Diet
Endemic exclusively to the Northern Luzon highlands of the Philippines, this species is well-adapted to montane forest ecosystems.
Where it Lives: It inhabits forested regions along mountain slopes and steep hillsides. Highly agile despite its size, it is equally at home high up among the canopy branches of tall forest trees and foraging on the forest floor.
Diet and Crop Impact: Primarily herbivorous, its natural diet consists of tender leaves, bark, buds, and forest fruits. However, when forests border agricultural clearings at the base of mountains, giant cloud rats occasionally descend to feed on cultivated crops, particularly maturing bananas planted in clearings near the forest edge.
Human Interaction and Conservation Status
Local Utilization: The meat of the Northern Luzon giant cloud rat is traditionally consumed as a delicacy by indigenous communities and local inhabitants in the northern highlands. Experts note that if properly stock-farmed and managed under sustainable programs, they could serve as an alternative source of protein.
Current Status and Protection: Unlike many other endemic Philippine mammals whose numbers are severely depleted, wild populations of the Northern Luzon giant cloud rat remain relatively stable in remote areas. However, because of localized hunting pressures and the need to protect native biodiversity, capturing, hunting, or collecting this iconic rodent is strictly regulated and protected under Philippine wildlife conservation laws.

( CLICK PHOTO TO SEE VIDEO RELATED TO ORIENTAL SMALL-CLAWED OTTER)
Oriental Small-clawed Otter
(Aonyx cinereus) Illiger 1815
Local Name : Dingguin, Asian Small-clawed Otter
The Oriental small-clawed otter (Aonyx cinereus), also known as the Asian small-clawed otter, is a remarkably small otter species.
Size and Proportions: It measures an overall length of 27 to 31 inches, which includes a tail spanning roughly 10 to 12 inches. It features a long, streamlined body supported by short legs and short, rounded feet. It is the smallest species of otter in the world.
Paws and Claws: The toes are more or less completely webbed, equipped with small claws that do not project past the tips of the digits.
Tail and Fur: Its tail is long, thick at the base, tapering, and slightly flattened. The coat consists of short, dense fur.
Coloration: The upperparts are a uniform chocolate brown (or dark brown with a subtle reddish tinge), while the underparts are a lighter brown, with the chin, throat, and sides of the neck often displaying lighter grayish-white highlights.
Minor variations in pelage color exist among individuals.
Habitat, Behavior, and Diet
The Oriental small-clawed otter is semi-aquatic and deeply tied to freshwater and coastal ecosystems.
Where it Lives: It stays in the immediate vicinity of water, usually along river banks, streams, mangrove swamps, estuaries, and dense vegetation close to waterways.
Nocturnal Habits: While occasionally active during the day or twilight, it is primarily nocturnal in habit, spending daylight hours hiding in dense cover or burrows.
On various occasions, individuals have been documented inhabiting "Nipa" swamps at night. Diet: It feeds on a diverse array of both aquatic invertebrates and vertebrates. Stomach contents analyzed from field specimens commonly yield remnants of freshwater fish and crabs, alongside frogs, rats, and waterbirds.
Reproduction: They breed and raise their young inside secure burrows excavated along the banks of rivers or creeks, typically producing litters of two to three kittens.
Geographic Distribution and Conservation Status
Distribution: In the Philippines, the Oriental small-clawed otter is restricted exclusively to the island of Palawan (including surrounding wetland habitats).
Regionally, the species is also widely distributed across mainland South and Southeast Asia, as well as the islands of Sumatra, Borneo, and Java. Human Interaction: Historically, its pelt has been utilized for crafting small souvenir items like caps and hats, while its meat is occasionally consumed locally by inhabitants in areas where it occurs.
Conservation Status: The wild population of the Oriental small-clawed otter is declining rapidly due to habitat loss, degradation of wetlands, and localized hunting pressures.
Consequently, Philippine wildlife protection laws restrict the hunting, capture, or trade of this vulnerable mustelid.
(Sundasciurus juvencus) Thomas 1908
(Sundasciurus juvencus) Thomas 1908
Local Name : Ananagsing, Bising, Tagsing, Laksoy
Size and Proportions: It features a moderately long, flattened tail (rather than a bushy one) with hairs at the tip noticeably elongated. Its pelage consists of well-defined, woolly underfur intermixed with stiffer, straight overfur. Its ears are small and flattened closely against the head.
Coloration: The middle of the back, sides, and outer sides of the legs are grizzled with a mix of grayish-brown and black, with individual hairs marked by a black ring and black tip. The sides of the body feature a similar grizzled texture intermixed with numerous white hairs. The underparts are pure white, save for the root of the tail, the anal region, and the borders of the abdomen, which display a brownish-red hue. The tail itself is bright brownish-red with a black tip, marked by hairs featuring a broad black ring.
Habitat, Behavior, and Diet
Endemic to the Palawan faunal region, this agile climber is well-adapted to both dense woodlands and human-altered agricultural landscapes.
Where it Lives: It inhabits pristine virgin forests and remnant patches of original lowland forests up to elevations of 1,200 to 1,400 meters in the hills and mountains. It is also frequently found in secondary-growth forest patches near cleared agricultural zones.
Daily Activity and Preferred Foods: Primarily diurnal, it is most active during the early mornings and late afternoons, spending its time leaping among tree branches. Its natural diet focuses heavily on the hard fruits of forest trees, showing a strong preference for the acorns of native oak species, which it gathers directly from branches or the forest floor.
Nesting and Coconut Palm Utilization: They frequently build secure nests in the crowns of coconut palms, tucking them safely into the axils of the leaves. In areas where coconut plantations border forests, large numbers of these squirrels feed on developing coconut fruits, occasionally causing significant agricultural damage.
Cornfield Raiding Tactics: In agricultural clearings established by kaingin (slash-and-burn) farming, these squirrels frequently raid crops like corn and camote (sweet potatoes). When foraging in a cornfield, a squirrel will scamper rapidly across the ground between corn rows, occasionally climbing stalks to strip back the husks of maturing corn ears. If disturbed, it darts down the stalk, leaps to the ground, scales criss-crossing fallen tree trunks on the forest floor, and vanishes back into forest cover.
Indirect Crop Destruction: Interestingly, squirrels often start unhusking a corn ear, disturb it, and abandon it. Once the husk is partially opened and exposed to moisture, it becomes vulnerable to fungal rot. Consequently, they destroy large numbers of corn ears indirectly—abandoning damaged crops to start fresh on a new plant during subsequent visits.
Geographic Distribution and Conservation Status
Distribution: The Northern Palawan tree squirrel is common but local in its distribution, found primarily across the northern regions of Palawan Island and nearby northern islands.
Human Interaction and Status: Locally, their meat is occasionally consumed as an alternative source of bushmeat when conventional sources are scarce. While some individuals are pursued as agricultural pests or captured for the pet trade, wild populations remain relatively stable, with no immediate, severe threats jeopardizing their overall survival status at this time.
VISAYAN OR PRINCE ALFRED'S SPOTTED DEER

( CLICK PHOTO TO SEE VIDEO RELATED TO VISAYAN OR PRINCE ALFRED'S SPOTTED DEER)
(Rusa alfredi) Sclater 1876
Local Name : Philippine Spotted Deer, Usa, Lagsaw
Coat and Distinctive Markings: Unlike its solid-brown cousin, the Visayan spotted deer is strikingly colorful. Its soft, moderately long fur features a rich dark brown upper body background marked by distinct, permanent rows of yellowish-white spots along the back, sides, and rear shoulders. The cheeks and top of the head are a pale brown, while the lower jaw and throat are whitish.
Limbs and Underparts: The neck and front shoulders are a uniform dark brown, the underparts are a creamy yellowish-white, and the limbs are uniform brown on the upper outer portions, fading to pale brown below and whitish on the inner sides.
Anatomy and Dimorphism: Both sexes share a similar coloration pattern. Fawns are born with prominent white spots that persist, fading only slightly into the distinct adult spotted pattern. Its antlers are less massive than those of the Philippine brown deer, featuring a short brow antler and a very short inward-pointing tine, paired with short ears that are nearly naked on their outer surface.
Habitat, Behavior, and Ecology
Where it Lives: The Visayan Spotted Deer historically shared ecological niches and habitat types similar to the Luzon brown deer, inhabiting dense original lowland and mid-mountain forests, as well as forest edges intersecting with grasslands.
Behavior and Diet: Highly secretive and predominantly nocturnal or crepuscular, its habits mirror those of other native deer. It relies heavily on deep forest cover for daytime shelter, emerging to feed on tender forest shoots, grasses, leaves, and fallen fruits. During the dry breeding season, stags utilize distinct vocalizations and scent-marking behaviors to attract mates.
Geographic Range and Conservation Status
Historical vs. Current Distribution: Once widely distributed across multiple central Philippine islands—including Panay, Negros, Cebu, Guimaras, Masbate, and Bohol—habitat destruction and intense hunting pressures have driven it to near-total extirpation across its former range. Today, it is extremely rare and confined almost exclusively to dense mountain rainforests in western Panay Island, particularly around the rugged slopes of Mount Madjaas and Mount Baloy (with small, managed captive-breeding assurance populations established elsewhere).
Threats and Strict Protection: Historically overhunted for its delicious meat, the species was pushed to the absolute brink of extinction. Consequently, the Visayan spotted deer is classified as Critically Endangered on the IUCN Red List, and hunting, capturing, or harming this magnificent animal is strictly prohibited and heavily penalized under Philippine wildlife protection laws.

Mindanao Tree Shrew
(Tupaia everetti) Thomas 1892
Local Name : Mindanao Slender-tailed Tree Shrew, Tarababuey, Klongi, Kologtsuey,
Tarra-Bahbooey
Size and Structure: While superficially resembling a tree squirrel, it features a more elongated snout, relatively large feet, and sharp, well-developed claws adapted for climbing and scratching.
Coloration: The upperparts—including the head, neck, body, tail, and outer limbs—display a dark brown to blackish-brown coloration, created by a fine grizzling effect where blackish and tawny hairs mix thoroughly with standard brown. The snout and sides of the head feature a warmer reddish-brown mix, while the feet are a darker brown than the legs.
Underparts and Markings: The under-surface, including the inner sides of the legs, is a striking orange-rufous (brightest around the chest), though the slaty-gray bases of the hairs show through in certain areas. The underside of the tail matches the upper side with an even mix of light and dark tones, and a signature orange-brown or rusty shoulder stripe marks the flanks, though somewhat ill-defined.
Habitat, Behavior, and Ecology
Endemic exclusively to the southern Philippines, the Mindanao tree shrew thrives in specialized mid-to-low elevation forest environments.
Where it Lives: It is commonly found inhabiting dense secondary-growth forests along agricultural clearings, as well as very thick bamboo jungles situated beside small streams and creeks.
Temperament and Territoriality: Highly energetic and easily excited, it is predominantly arboreal (though frequently foraging on the ground). Unlike social mammals, it is fiercely anti-social and territorial, establishing strict home ranges that individuals actively defend against intruders of the same species.
Diet: As an opportunistic omnivore, its natural diet consists heavily of insects, grubs, and soft forest fruits.
Geographic Range: It is endemic to Mindanao and surrounding island habitats. Notable specimens have been collected from major southern peaks including Mount Apo, Mount McKinley, Mount Todaya, and Mount Malindang in Zamboanga del Norte, as well as on Dinagat Island off the northeastern coast of Surigao del Norte.
Ecological Importance and Conservation Status
Ecological Contributions: By consuming large quantities of insects, the Mindanao tree shrew acts as a natural pest controller. Simultaneously, its consumption and subsequent excretion of forest fruits make it an effective seed disperser, aiding in the regeneration of native flora.
Current Status and Threats: While current wild populations remain relatively stable across protected montane and secondary forests, the ongoing loss and fragmentation of its natural woodland habitats represent the primary long-term threat to its survival.

Golden-capped Fruit Bat
(Acerodon jubatus ) Eschscholtz 1831
Local Name : Giant Golden-crowned Flying Fox, Paniki, Kabog
Size and Proportions: It boasts an impressive wingspan stretching more than 5.5 feet (approx. 1.7 meters), a total body length of about 14 inches, and a robust weight reaching up to 1.2 kilograms (2.6 lbs).
Distinctive Coat and Golden Crown: Its fur on the sides of the face, forehead, above the eyes, and throat ranges from brownish-black to jet black. The top of the head features black hair individually tipped with yellow or buff, creating a striking, distinct golden-yellow crown or cap (giving the species its common name).
Collar and Underparts: The nape is golden-yellow, transitioning to an orange-buff or orange-yellow shade on the back of the neck, and expanding into a complete rufous or chestnut-rufous collar around the underside of the neck. The fur on the undersurface of the body is blackish intermixed with silvery tips.
Habitat, Behavior, and Ecology
Endemic exclusively to the Philippines, this magnificent megabat is a crucial architect of the forest ecosystem.
Colony Life and Roosting: They live in large, highly social colonies—often numbering in the thousands—hanging heavily from the branches of tall trees in dipterocarp forest patches, interior mountain forests, and coastal mangrove swamps on small islands. During the day, dense clusters of sleeping bats resemble giant black bags suspended from the canopy. In many regions, they roost in mixed-species colonies alongside other giant fruit bats like the Malayan flying fox (Pteropus vampyrus).
Diet and Seed Dispersal: As a specialized frugivore, its diet relies heavily on the fruits of various wild fig (Ficus) species. Because they travel long distances nightly to forage and excrete seeds across wide swaths of land, they act as essential seed dispersers and forest regenerators.
Breeding Season: The breeding season typically aligns with the dry summer months in the Philippines, occurring most frequently between April and May. Females typically give birth to a single pup per year, which they carry or leave in nursery roosts.
Geographic Range and Conservation Status
Native Distribution: The Golden-crowned Flying Fox is distributed across major island groups in the Philippines, with historical and current records spanning Basilan, Mindanao, Cebu, Bohol, Siquijor, Negros, Boracay, Samar, Mindoro, Marinduque, Polillo, Mount Banahaw, the Sierra Madre mountain range in Luzon, the Subic Bay Watershed Reserve, and forested areas in Northern Luzon.
Threats and Legal Protection: Historically, giant fruit bats were heavily hunted as a source of bushmeat. Combined with massive deforestation, roost-site disturbance, and hunting pressures, their populations experienced catastrophic global declines. Today, the golden-capped fruit bat is classified as Endangered on the IUCN Red List and is strictly protected under national legislation, such as the Philippine Wildlife Resources Conservation and Protection Act (Republic Act No. 9147), making hunting or capturing them illegal.

PALAWAN BINTURONG
(Arctictis binturong whitei) J. A. Allen 1910
Size and Proportions: It reaches an impressive overall length ranging from 4 feet 3 inches to 4 feet 7 inches, and can weigh as much as 25 kilograms (approx. 55 lbs). It features an elongated body supported by short legs with broad, naked soles and palms.
Head and Tail: Its head is broad at the back and tapers toward a pointed snout, framed by numerous long facial whiskers (vibrissae) that can reach the ears. Its ears are small and rounded, tipped with prominent tufts of long hair. Crucially, it possesses a long, muscular prehensile tail—making it one of the few Old World carnivorans with a tail capable of gripping branches.
Coat and Distinctive Coloration: Its pelage consists of long, coarse, and rough fur. The upperparts are black washed with a reddish-brown or fulvous tint, driven by hairs featuring deep black bases and broad fulvous tips (which impart a warm, tawny wash across the forelegs and larger body sections). The face is dark with white-tipped hairs, the entire neck is circled in black, and the outer ears feature heavy black tufts bordered with white or yellowish-white. The sparse underparts feature crinkled, woolly hair ranging from dark fulvous on the chest to a pale silvery-fulvous across the abdomen and extending down the proximal two-thirds of the tail.
Habitat, Behavior, and Diet
Endemic exclusively to the Palawan faunal region in the Philippines, this unique mammal leads a specialized arboreal life.
Where it Lives: The Palawan binturong inhabits dense vegetation within both pristine primary forests and secondary-growth woodlands, ranging from the lowlands up into hills and lower mountain slopes of roughly 200 meters above sea level.
Arboreal Habits: Highly adapted to life in the canopy, it uses its prehensile tail as a fifth limb to navigate high up among the branches of dipterocarp trees, resting deep within dense clusters of leaves where it remains heavily concealed during the day.
Nocturnal Lifestyle and Eyeshine: Primarily active at night (nocturnal), it is most easily detected in the dark when a flashlight or headlamp beam catches its bright, luminous eyes, which will stare fixedly into the light for brief moments before it retreats into foliage.
The Popcorn Scent: A fascinating characteristic of the binturong is its scent glands, which secrete a musky fluid containing 2-acetyl-1-pyrroline—the exact compound that gives freshly popped popcorn its signature aroma.
Diet: As an opportunistic omnivore, its diet consists primarily of ripe forest fruits (playing a major role in seed dispersal), supplemented by small animals, rodents, birds, and occasionally poultry when forests border rural settlements.
Geographic Distribution and Conservation Status
Distribution: While this specific subspecies (A. b. whitei) is endemic to Palawan Island, broader binturong species are distributed across mainland South and Southeast Asia (from northeast India and Burma to Vietnam and the Malay Peninsula) as well as the islands of Sumatra, Java, and Borneo.
Human Interaction: Historically, its coarse fur has been utilized for making caps and winter clothing wraps, its meat is occasionally consumed locally as bushmeat, and individuals are sometimes regarded as minor pests when they raid rural poultry.
Conservation Status and Protection: Due to accelerating deforestation, habitat fragmentation, and historical hunting pressures, wild populations of the Palawan binturong have experienced notable declines. Consequently, capturing, hunting, or trading the binturong is strictly prohibited and protected under Philippine wildlife conservation laws to safeguard its survival in the wild.

( CLICK PHOTO TO SEE VIDEO RELATED TO CALAMIAN DEER)
The Calamian deer (Axis calamianensis or Hyelaphus calamianensis), often referred to as the Calamian hog deer, is a small species of deer native to the Philippines.
Size and Proportions: It is slightly smaller than the Philippine brown deer (Rusa marianna), measuring an overall length of 4 feet up to 4 feet 7 inches, with a shoulder height ranging from 2 feet up to 2 feet 6 inches. Compared to the stockier hog deer species found on mainland Asia, it features noticeably longer, darker-colored legs.
Coat and Distinctive Markings: The general coloration of its pelage is a rich tawny brown, with stags (males) growing progressively darker as they mature. Distinct light markings appear on the throat just below the jaw, accompanied by a white band delineated by a darker stripe on the snout near the nose. The inner surfaces and bases of the ears, surrounding areas, and the under-surface of the tail are starkly white.
Antlers: A key distinguishing anatomical feature separating it from other native Philippine deer species (which typically feature two-tined antlers) is that male Calamian deer possess three-tined antlers, which they shed and regrow annually.
Habitat, Behavior, and Ecology
Name Origin and Anti-Predator Behavior: The Calamian deer is crepuscular to diurnal in habit (active primarily around dawn and dusk, as well as parts of the day).
Much like other hog deer, it possesses the unique behavioral habit of creeping its head very low to the ground and darting rapidly through dense undergrowth like a wild hog—hence the name "hog deer". This specialized locomotion serves as an evolutionary adaptation to navigate dense foliage and shield itself from avian predators or threats from above. Preferred Terrain: They favor open grasslands, transition zones, open secondary-growth forests, and secondary woodland patches where they can forage for shoots, twigs, and leaves.
Geographic Range and Conservation Status
Restricted Distribution: The Calamian deer is strictly endemic to the Calamian Islands, an island group located north of Palawan in the Philippines.
Its core populations are restricted primarily to Busuanga Island, the Calauit Game and Wildlife Sanctuary, and Culion Island. Threats and Strict Legal Protection: Due to its extremely limited natural geographic range, historical habitat destruction from agricultural expansion, and relentless overhunting for bushmeat and antlers, the species faces a high risk of extinction.
Consequently, the Calamian deer is classified as Endangered on the IUCN Red List, and Philippine wildlife protection laws strictly prohibit hunting, capturing, or collecting this vulnerable deer species.
PHILIPPINE PALM CIVET
( CLICK PHOTO TO SEE VIDEO RELATED TO PHILIPPINE PALM CIVET)
Size and Proportions: While sharing a general body shape with the larger Tangalunga civet (Viverra tangalunga), the Philippine palm civet is distinctly smaller and features slightly longer, more well-proportioned legs. Its tail is long and non-prehensile (shorter than the combined head and body), ending in a triangular head with a pointed nose and long whiskers (vibrissae) that reach back to the ears.
Paws and Scent Glands: It possesses semi-retractile claws well-suited for climbing and well-developed perineal scent glands.
Coat and Distinctive Coloration: Its soft pelage consists of longer, coarser overfur mixed with shorter underfur. The upperparts display a yellowish-brown hue with a golden luster, averaging darker along the middle of the back. The front of the head features a grayish band across the forehead just above the eyes, while the crown and ears are dark brown. The underparts (especially the breast) are a grayish-yellow, the tail is uniformly brownish, and the legs are brown inside and out. Overall coat colors vary noticeably among individuals, even within the same geographic population.
Habitat, Behavior, and Diet
The Philippine palm civet is highly adaptable and comfortable living near human settlements.
Where it Lives: It is commonly encountered in open country, agricultural fields, rural villages, and grasslands situated close to original or secondary forest patches.
Nocturnal Habits and Nesting: Strictly nocturnal, it spends daylight hours sleeping securely inside nests built on horizontal tree branches among dense foliage or tucked deep within bamboo clumps. These nests are neatly constructed from arranged leaves to form a flat resting platform.
Agile Climber: Exceptionally agile and an expert tree-climber, it navigates complex, angled, vertical, and horizontal branches with ease.
Diet and the Origin of "Kape Alamid": As an opportunistic frugivore and omnivore, its diet consists heavily of cultivated fruits (such as papayas and santol) and wild forest fruits like wild figs. They are particularly famous for feeding on ripe coffee berries. After digesting the fruit pulp and excreting the intact coffee beans, the seeds are gathered, thoroughly cleaned, and processed to produce "kape alamid" (known globally as kopi luwak), which ranks among the most expensive gourmet coffees in the world. Additionally, they occasionally prey on young nesting birds and backyard poultry chicks.
Ecological Role, Distribution, and Conservation Status
Geographic Distribution: The Philippine palm civet is widely distributed throughout most of the major and minor island groups across the Philippines.
Ecological Benefits: By feeding on fruits across wide ranges and excreting the seeds intact, it acts as an essential seed disperser for forest regeneration, while also contributing marginally to rodent population control.
Population Status and Protection: Unlike many endangered endemic mammals, wild populations of the Philippine palm civet remain relatively stable and resilient. However, because of occasional persecution as poultry pests and the need to regulate wildlife trade, national wildlife protection laws in the Philippines restrict and regulate the hunting and collection of this species.
Cebu Bearded Pig,
Coat and Mane: Its body is covered in somewhat scanty, coarse hair, ranging from a lighter silvery-brown in larger mature males to a much darker shade in smaller females. A defining characteristic of adult males is a prominent, bristly mane running from the top of the head all the way down the back to the rear end. This long mane often hangs forward over the face, nearly obscuring the eyes.
Snout and Facial Warts: Like other true wild pigs (Sus), it features an elongated snout ending in a flat, circular nasal disc (though slightly shorter than that of the Palawan bearded pig). Its facial warts are relatively small and inconspicuous compared to other warty pig species, occurring only on males where they serve as protective facial padding during aggressive combat and tusking clashes with rival boars.
Habitat, Behavior, and Ecology
Where it Lives: Historically, the Visayan warty pig roamed across a vast altitudinal range from coastal primary and secondary lowland forests up to high-elevation mossy forests reaching 5,250 feet (approx. 1,600 meters) above sea level. Due to extreme lowland deforestation, surviving wild populations are now typically restricted to higher elevations above 2,600 feet.
Adaptability and Hybridization Pressures: While they can occasionally tolerate degraded environments like cogonal grasslands if thick vegetation and brush are available for daytime cover, populations surviving in degraded areas face severe genetic threats from interbreeding with feral domestic pigs, risking the genetic integrity of pure Visayan warty pigs.
Diet and Habits: Highly social and predominantly nocturnal or crepuscular, they root through the forest floor using their snouts to feed on fallen forest fruits, roots, tubers, earthworms, and agricultural crops when foraging near forest edges.
Geographic Range and Conservation Status
Native Distribution: The Visayan warty pig is endemic exclusively to the west-central Philippines. Historically found across six major islands—Panay, Negros, Cebu, Guimaras, Masbate, and Bohol—it was long presumed completely extinct on Cebu and Guimaras. Today, viable wild populations are restricted almost entirely to remote mountain forest remnants on Panay and Negros, with unconfirmed reports suggesting tiny surviving pockets on Masbate.
Threats and Strict Legal Protection: Driven to the absolute brink of extinction by rampant habitat loss, agricultural clearing, and heavy poaching for bushmeat, the Visayan warty pig is classified as Critically Endangered on the IUCN Red List. Consequently, Philippine wildlife conservation laws (Republic Act No. 9147) strictly prohibit and heavily penalize anyone caught hunting, killing, capturing, or trading this endangered native suid.

LUZON BUSHY-TAILED CLOUD RAT
( CLICK PHOTO TO SEE VIDEO RELATED TO LUZON BUSHY-TAILED CLOUD RAT)
Luzon Bushy-tailed Cloud Rat
Size and Proportions: It reaches an impressive total length of about 2.5 feet, with its heavy, plume-like tail accounting for roughly 16 inches of that measurement. It features an elongate body supported by short feet covered in short fur that completely conceals the skin, complete with well-developed tufts of hair surrounding each claw.
Facial Features and Crest: Its face is adorned with very long facial whiskers (vibrissae), supplemented by two elongated vibrissae situated above the eyes and two more located behind them. Its ears are small and almost totally hidden within dense fur. A prominent, distinctive crest on the anterior face and forehead starts short near the nose and lengthens gracefully toward the crown.
Pelage and Coloration: The pelage is dense and long, composed of a soft woolly underfur intermixed with wavy or straight overfur that grows longer and coarser toward the rump. The overall pelage color is predominantly blackish, though variable (sometimes exhibiting whitish or brownish patches on the anterior body or irregular white areas on the underside). The crown crest is brownish-black, neck and shoulder overfur is solid black, the underfur transitions from gray to dark blackish-gray at the base, and the area directly behind the ears is a naked-looking grayish patch lacking overfur.
Habitat, Behavior, and Complex Nesting
Endemic exclusively to the high mountain ranges of Central Northern Luzon (particularly prevalent in the Mountain Province and Cordillera administrative regions), this cloud rat is a true montane specialist.
Where it Lives: It thrives in cold, misty high-elevation forests at roughly 2,000 meters above sea level and higher, inhabiting cold mossy cloud forests near mountain summits, as well as the edges of pine and scrub oak stands. It routinely nests and shelters inside natural holes and cavities in pine tree trunks or deep within hollows among tree roots.
Nocturnal Habits and Diet: Strictly nocturnal, it spends daylight hours resting inside its nest. Foraging entirely in the arboreal canopy, it feeds on fresh forest fruits collected directly from branches (never eating fallen fruits from the ground), alongside tender leaf buds, flowers, and the inner bark of young pine tree shoots.
Master Architect (The Nest): The Luzon bushy-tailed cloud rat constructs an exceptionally large, bulky, and sophisticated spherical nest high up in the top branches of oak or pine trees. The outer platform is built from interwoven cut branches, walled in with a thick, dense perimeter of smaller leafy branches that extend upward to serve as a combined roof and shelter. Inside this fortress is a cozy, insulated chamber thickly lined with a soft mixture of pine needles, hanging mosses, and ferns.
Human Interaction and Conservation Status
Local Utilization and Pelts: Historically, the meat of the Luzon bushy-tailed cloud rat has been highly valued as a traditional delicacy and source of protein by indigenous communities in the Mountain Province. Additionally, its dense, beautiful pelt has occasionally been utilized to craft unique caps, scarves, and winter mufflers. Researchers note that if managed under careful captive-breeding or stock-farming programs, they could theoretically serve alternative agricultural roles.
Threats and Strict Legal Protection: Due to historical overhunting for bushmeat, timber harvesting, and climate vulnerabilities affecting high-altitude cloud forests, populations have experienced severe contractions. Consequently, the Luzon bushy-tailed cloud rat is classified as a threatened species, and hunting, capturing, or collecting this animal is strictly prohibited and penalized under Philippine wildlife conservation laws (Republic Act No. 9147).

PHILIPPINE PANGOLIN
( CLICK PHOTO TO SEE VIDEO RELATED TO PHILPPINE PANGOLIN)
Philippine Pangolin
Palawan Pangolin or Scaly Ant-eater
Size and Proportions: It measures between 26 to 30 inches in overall length, which includes a powerful tail spanning roughly 10 inches.
The Horny Armor Scales: The dorsal surface of its head, neck, body, and the entire tail are heavily covered by broad, overlapping, translucent horny scales made of keratin. Conversely, the belly, chin, sides of the face, and inner sides of limbs lack scales and are sparsely covered with fine, stiff hairs (thickest around the ears).
Anatomy and Adaptations: It features a conical head covered in small scales forming a triangular area, a hairless nose, and a remarkably small, toothless mouth where the upper jaw extends far beyond the lower jaw. Its tiny eyes and ears sit within elongated grooves on the sides of the head, with the ears positioned just behind the eyes featuring a raised, rounded skin fold.
Tail and Limbs: The broad tail is covered above by three rows of scales (with the median row being the largest) and flanked by a single row of strongly keeled folded scales. Its short, muscular forelegs and hind legs possess five digits equipped with powerful digging claws—particularly the enlarged middle claw on the front feet. The general coloration of its skin and scales is a dirty pale yellowish-white.
Habitat, Behavior, and Specialized Diet
Endemic exclusively to the Palawan faunal region—specifically Palawan, Culion, and Busuanga islands—this secretive mammal is uniquely adapted to a specialized diet and lifestyle.
Where it Lives: It inhabits dense vegetation patches and remnant lowland forests located close to cogonal grasslands.
Nocturnal and Burrowing Habits: Primarily nocturnal, it spends daylight hours resting safely inside deep earth burrows or hollow logs. Because of its tiny eyes, it relies heavily on an acute sense of smell and hearing rather than sight.
The Termite Specialist: The pangolin is a strict insectivore specializing in termites and ants. Using its massive front claws, it rips open termite nests (favoring arboreal nests or the bases of termite mounds) and deploys a long, highly extensible, sticky tongue to sweep up thousands of termites and ants. It occasionally consumes stinging red and black ants as well.
Prehensile Tail and Climbing: The horny pad at the underside tip of its powerful tail assists in climbing and anchoring to tree branches. It is frequently observed gripping a branch with its tail and hanging vertically, appearing as though fast asleep. When threatened, it rolls into an impenetrable, tight ball of sharp scales, and can exude a foul-smelling musk from anal glands when heavily startled.
Ecological Benefit: As a voracious consumer of insects, the Philippine pangolin serves as an invaluable natural pest controller, keeping wild termite populations in check and preventing structural forest damage.
Human Pressures and Traditional Trade: Historically, its meat has been consumed as local bushmeat. Tragically, it is also one of the most heavily trafficked mammals in the world due to the illegal international trade driven by demand for its keratin scales, which are falsely prized in traditional Asian pharmacopeias (particularly in China) for medicinal properties, along with its skin used for leather articles.
Conservation Status: Due to rampant poaching, illegal smuggling, and continuous forest habitat loss, wild populations have plummeted. Consequently, the Philippine pangolin is classified as Critically Endangered on the IUCN Red List, and hunting, capturing, killing, or trading this animal is strictly prohibited and heavily penalized under national wildlife protection laws (such as Republic Act No. 9147).

PALAWAN FLYING SQUIRREL
( CLICK PHOTO TO SEE VIDEO RELATED TO PALAWAN FLYING SQUIRREL)
Palawan Flying Squirrel
The Palawan flying squirrel (Hylopetes nigripes), locally known as the tapilak, is a small rodent—significantly smaller than some of the larger giant flying squirrel species found elsewhere in the Philippines—measuring an overall length of about 24 inches, with its long, heavily furred tail accounting for 10 to 12 inches of that measurement.
Head and Pelage: It features a cute, squirrel-like head adorned with very dense, long, heavy fur covering its body and tail, particularly thick along the upperparts.
The Gliding Membrane (Patagium): Well-developed, fur-covered lateral membranes stretch smoothly between its front and hind limbs, forming an efficient aerodynamic parachute for gliding when the limbs are fully extended forward and backward.
Cartilage Spreader and Steering: On the outside of each wrist, the membrane is supported by a stiff cartilage rod that acts as a structural spreader. Embedded within the membrane sheets are specialized muscle fibers that, when contracted or relaxed, allow the animal to expertly steer, shift tension, and change direction mid-air while gliding.
Color Variation: The pelage exhibits remarkable color variation among individuals, ranging from almost pure white or grayish-white to grayish-buff or rich brown, transitioning from uniform coloration to speckled, spotted, or blotched patterns.
Habitat, Behavior, and Diet
Endemic exclusively to the Palawan faunal region, this specialized glider is well-adapted to tropical forest ecosystems.
Where it Lives: It inhabits pristine virgin forests—including lowland dipterocarp forests near the coast—extending upward to elevations of 2,000 meters or higher within mid-mountain forests. It thrives both within large continuous forest blocks and inside forest patches interspersed with agricultural clearings.
Nocturnal Habits and Vocalizations: Strictly nocturnal, it spends daylight hours sleeping securely inside natural tree cavities or tucked into the forks between tree branches. It becomes active at night starting right at dusk after the sun completely sets, remaining active until just before dawn. It moves fast and frequently emits high-pitched, whistling-hissing notes, making it easy for observers to trace its location among the canopy.
Diet: Its natural diet consists primarily of fresh forest fruits, nuts, tender inner bark, young succulent buds, and forest grubs or insects.
Gliding Mechanics: When moving between trees, the Palawan flying squirrel can effortlessly glide as far as 50 meters (over 150 feet). Launching from the highest points of a tree trunk or high canopy branches, it swoops downward across open space, typically landing on the lower portion of a target tree's trunk before scrambling upward.
Geographic Range and Conservation Status
Distribution: The Palawan flying squirrel is endemic to Palawan Island, but historical and field records indicate it may also inhabit nearby smaller island neighbors within the Palawan chain, including Culion, Busuanga, Coron, and Bancalan Island.
Conservation Status: Because of its reliance on primary and secondary lowland forests that face ongoing timber extraction and agricultural clearing, its natural habitats are contracting.
Consequently, it is categorized by the IUCN as Near Threatened, highlighting the need to protect remaining forest cover across Palawan to secure its future.

PHILIPPINE WARTY PIG
( CLICK PHOTO TO SEE VIDEO RELATED TO PHILPPINE WARTY PIG)
Philippine Warty Pig
Luzon Wild Pig
Build and Hooves: It features a stocky, powerful body covered in coarse, stiff hair. Like other wild pigs, it walks on narrow four-toed feet where only the two central toes bear weight, while the two small lateral toes touch the ground only in soft mud or deep soil.
Facial Features and Tusks: It is characterized by a long snout ending in a flat, expanded, mobile disc with centrally placed nostrils, small eyes, and long ears. Its teeth are strong and numerous, featuring well-developed upper and lower canines that sharpen into razor-sharp edges by continuously rubbing against each other.
Coat and Mane: The general body color is blackish. A well-developed crest of long, stiff black hairs runs down the middle of the back (particularly pronounced in adult males). The sides feature sparse silvery-white bristles mixed with black, creating a frosted or whitening effect, while the legs are black, and the short tail ends in a tuft of long black hairs.
Habitat, Behavior, and Social Structure
Endemic exclusively to the Philippines, the Philippine warty pig is adaptable yet increasingly rare.
Where it Lives: It inhabits a wide range of ecosystems, from coastal seacoasts and open parang (grassland-forest mosaics) up to dense primary and secondary mountain forests. Regionally, it has historical and current distributions spanning Luzon, Samar, Leyte, and large forested areas in Mindanao, though it is presumed extinct on Marinduque due to historical overhunting and habitat loss.
Social Habits: They can be solitary, travel in pairs during breeding seasons, or form family groups numbering 7 to 12 individuals—typically consisting of a dominant boar, several sows, and growing piglets.
Nocturnal Foraging and Plowing: While active during the day, they are primarily nocturnal. Using their powerful snouts as living plows, they dig up extensive patches of ground to feed on nutrient-rich grass rootstocks, wild tubers, camote (sweet potato) roots and leaves, and gabi (taro). When forests border agricultural clearings, they frequently raid farms, feeding on corn, rice, cassava, and root crops.
Breeding and Aggressive Defense: Females select secure nesting sites, such as the deep hollows between the massive buttresses of giant dipterocarp trees surrounded by dense brush. Litters average 5 to 8 piglets. Like other wild boars, they are notoriously dangerous and aggressive when cornered, particularly protective sows guarding their young.
Human Interaction and Conservation Status
Culinary Importance and Hunting: Wild pig meat has historically served as a vital source of bushmeat across the Philippines (consumed by most non-Muslim communities). Local trappers frequently hunt them to sell fresh or dried meat in nearby towns.
Conservation Status: Due to intensive hunting pressure, habitat fragmentation, and agricultural conflicts, wild populations of the Philippine warty pig are declining rapidly. Consequently, hunting, trapping, or collecting this native species is strictly restricted and protected under national wildlife conservation laws (Republic Act No. 9147).
