36 Types of Snakes in the Philippines: From Harmless Ratsnakes to Deadly Cobras
October 12, 2026
Step off a trail in Palawan or wade into a rice paddy in Luzon, and there is a fair chance a snake is somewhere nearby, whether you notice it or not. The types of snakes in the Philippines range from a blind, worm-like burrower small enough to hide in a flowerpot to a reticulated python that can outweigh a grown man. Herpetologists have documented at least 112 species of terrestrial snakes across the archipelago, and 74% of those species are endemic to the islands, found in 41 genera with 12% of those genera unique to the country.
That isolation has produced snakes found nowhere else on Earth, from spitting cobras to a family of burrowing elapoids that evolved separately for tens of millions of years. This guide walks through 36 species and species groups that represent the full range of Philippine snake life, sorted by the families and habitats where you’re most likely to run into them.
1. Brahminy Blindsnake (Flowerpot Snake)
The Brahminy blindsnake, Indotyphlops braminus, is often mistaken for an earthworm until someone notices its smooth, shiny scales and forked tongue. It rarely grows past 15 centimeters, spends nearly its entire life underground, and reproduces without a mate, which is how it has hitchhiked in potted plants to nearly every warm region on the planet. Blind snakes are named for their reduced, vestigial eyes, a trait that suits a species that hunts ant and termite larvae by scent rather than sight. Gardeners across the islands sometimes confuse it with the insects in the Philippines it actually feeds on.
2. Common Mock Viper
The common mock viper, Psammodynastes pulverulentus, earns its name by flattening its head and striking in a viper-like bluff whenever it feels cornered, despite carrying only a mild, rear-fanged venom that poses little threat to people. It belongs to its own small family, one that iNaturalist’s regional checklist lists as containing just a single Philippine species. Coloration varies from reddish-brown to nearly black, letting it blend into leaf litter on forest floors and plantation edges alike. It behaves a bit like the harmless, defensively-bluffing garter snakes familiar to many North American readers, minus the live-bearing habits.
3. Reticulated Python
Few Philippine snakes inspire as much awe, or as many exaggerated stories, as the reticulated python. Reticulated pythons are the only pythons that inhabit the rainforests of the Philippines, and as the longest snake species in the world they may reach more than 25 feet in length and weigh more than 300 pounds. Primarily nocturnal, they kill rats, birds, pigs, and goats by constriction rather than venom, wrapping prey in muscular coils until breathing stops. Most individuals encountered near villages are far smaller than the record-breakers, and this non-venomous species plays an important role in controlling rodent populations across the same lowland rainforest habitats found throughout Southeast Asia.
4. Oriental Whipsnake
Slender, fast-moving, and almost impossibly thin for its length, the Oriental whipsnake (Ahaetulla prasina) hunts by day among the branches of shrubs and forest edges, relying on binocular vision from horizontally slit pupils to judge distance before striking at lizards and frogs. Non-venomous snakes that inhabit the Philippines include long slender whip snakes such as the Oriental whip snake, alongside wolf snakes, bronzebacks, and flying snakes. Its green or brown coloring lets it disappear against foliage almost instantly once it stops moving. Similar whipsnake lineages turn up among the diverse reptiles in India, underscoring how widely this arboreal hunting style has spread across South and Southeast Asia.
5. Philippine Cobra
The Philippine cobra, also called the Philippine spitting cobra or northern Philippine cobra, is a stocky, highly venomous species of spitting cobra native to the northern regions of the Philippines, where it is known locally as ulupong. It can eject venom accurately toward an intruder’s eyes as a defensive tactic long before striking, causing intense pain and potential injury if untreated. Clinical reports describe the bite as producing rapid, severe symptoms rather than gradual ones. Neurotoxicity is the predominant clinical feature of Philippine cobra envenomation, and respiratory paralysis often develops rapidly, in some cases within 30 minutes of the bite.
Important Note: Snakebite from any Philippine cobra species is a medical emergency requiring immediate transport to a hospital equipped with antivenom. This article is for identification and educational purposes only and is not a substitute for professional medical or emergency guidance.
6. King Cobra
The king cobra (Ophiophagus hannah) is the longest venomous snake on the planet, and Philippine specimens are no exception to its reputation for size. This large, powerfully built snake can reach up to 5.5 meters in length and 9 kilograms in weight, varying mainly olive-green or black with pale yellow cross bands along the body. Unusually among elapids, its diet leans heavily on other snakes, which it locates and overpowers using size and a surprisingly fast strike. Despite the fearsome build, king cobras generally avoid confrontation and retreat when given the chance, saving aggression for nest defense. Comparable size records among the world’s other dangerously large snakes in Africa rarely approach what this species can achieve in Philippine forests.
7. Northern Philippine Cobra
“Northern Philippine cobra” is simply the geographic name herpetologists use for the same species covered above, Naja philippinensis, emphasizing that its natural range is restricted to Luzon and neighboring northern islands rather than the whole archipelago. That distinction matters clinically, since the country’s only cobra antivenom was developed against this specific population’s venom. This WHO Category 1 venomous snake of medical importance produces a venom dominated by three-finger toxins, which make up roughly two-thirds of the total venom proteins, alongside a substantial share of phospholipases A2. Farmers working rice paddies in Luzon report the majority of documented bites, a pattern tied to the snake’s preference for irrigated lowland habitat.
8. Southeastern Philippine Cobra (Naja samarensis)
Also called the Samar cobra, Naja samarensis fills the ecological role of its northern cousin but across an entirely different part of the country. The Philippines has two endemic cobra species: the Philippine cobra distributed in the northern Philippines, and the Samar cobra found in the southern Philippines. Its venom proteome is dominated even more heavily by three-finger toxins than the northern species, and current treatment options are limited. Both the Philippine cobra and Samar cobra are WHO Category 1 medically important venomous snakes, yet Philippine cobra antivenom is the only antivenom available in the country despite uncertain neutralization capacity against Samar cobra venom. That antivenom gap makes avoidance and rapid hospital transport especially critical in the Visayas and Mindanao regions where this cobra lives, a concern that echoes debates around venomous snake management seen with venomous snakes in South Carolina and other regions where antivenom stock is limited.
9. Equatorial Spitting Cobra
The equatorial spitting cobra (Naja sumatrana) is primarily a Sundaic species shared with Malaysia and Indonesia, reaching the southernmost fringes of the Philippine archipelago near Borneo. Like its northern relatives, it can spray venom defensively toward a perceived threat’s face rather than relying solely on a bite. Coloration in this species tends toward uniform black or dark brown, distinguishing it from the more patterned northern cobras at a glance. Anyone who has read about the defensive spitting behavior of snakes in Egypt, where certain cobra species share this same trick, will recognize the strategy immediately.
| Species | Primary Range | Key Trait |
|---|---|---|
| Philippine Cobra (N. philippinensis) | Northern Luzon and nearby islands | Only species with a dedicated antivenom |
| Southeastern Philippine Cobra (N. samarensis) | Visayas and Mindanao | No species-specific antivenom available |
| Equatorial Spitting Cobra (N. sumatrana) | Southernmost islands near Borneo | Predominantly dark, uniform coloring |
10. Long-glanded Coral Snake (Maticora intestinalis)
Small, secretive, and rarely seen, the long-glanded coral snake carries venom glands that make up an unusually large share of its body. Long-glanded coral snakes reach an average adult length of only 0.3 meters, yet their elongated venom glands extend posteriorly for about one-third of the body length. That anatomy lets a relatively short snake deliver a disproportionately large venom dose. Its warning coloration of black, red, and cream bands plays the same predator-deterrent role as the mimicry seen in America’s milk snakes, which famously copy coral snake patterns without carrying any venom themselves.
11. Asiatic Coral Snake (Hemibungarus/Calliophis spp.)
The Philippines hosts its own endemic branch of Asiatic coral snakes in the genus Hemibungarus, a group found nowhere outside the archipelago. Endemic Philippine snake genera include Hemibungarus, represented by three species, alongside additional coral snake diversity in the wider genus Calliophis. Both Asiatic and long-glanded coral snakes share small heads not distinct from the body, a slender cylindrical form with a short tail, and small eyes with round pupils. These snakes are secretive burrowers that surface mainly at dusk, and encounters with people are uncommon compared with cobras, though bites should still be treated with the same urgency applied to any coral-snake relative found among venomous snakes in Florida and the southeastern United States.
12. Yellow-lipped Sea Krait (Laticauda colubrina)
Banded in bold black and pale blue-gray, the yellow-lipped sea krait spends much of its life moving between land and sea, coming ashore on limestone islets to digest meals, mate, and lay eggs. This species is capable of producing up to ten times the lethal dose of venom required to kill, though its docile temperament and small, rear-positioned fangs mean bites on people are rare. It hunts almost exclusively for eels among coral reefs and rocky crevices, using a paddle-shaped tail for propulsion. Divers around Palawan and the Visayas frequently photograph this species basking on rocks near the same reefs that shelter the region’s crabs, a habitat overlap shared with many crabs in the Philippines.
13. Common Sea Snake
“Common sea snake” is an umbrella term applied to several fully marine species in the genus Hydrophis that never leave the water and have even lost the enlarged belly scales terrestrial snakes use for traction on land. Unlike sea kraits, these true sea snakes give birth to live young at sea rather than returning to shore to lay eggs. Sea snakes must surface to breathe air, though some can remain underwater for up to eight hours, dwelling among mangroves, rivers, lakes, and streams, with a few found in the open ocean. Paddle-like tails and laterally compressed bodies make them strong swimmers but nearly helpless if stranded on dry land.
14. Wolf Snake
Wolf snakes get their name from a mouthful of enlarged front teeth that resemble a small canine’s bite, an adaptation suited to gripping slippery lizards and skinks. The banded wolf snake is a common, wide-ranging species that spends most of its time on the forest floor, feeding on small lizards. Several wolf snake species in the genus Lycodon share a banded black-and-white or black-and-yellow pattern that causes them to be mistaken for venomous kraits, despite being completely harmless. That mimicry strategy parallels defensive coloring documented among snakes in Alabama, where similar banded patterns confuse predators and people alike.
15. Bronzeback Snake
Bronzeback snakes, typified in the Philippines by species such as Dendrelaphis pictus, are lithe, fast-moving daytime hunters that glide through low branches searching for frogs and lizards. Their name comes from a metallic bronze or olive sheen along the back that catches sunlight as the snake moves. Unlike thicker-bodied colubrids, bronzebacks rely on speed and agility rather than constriction, often escaping into dense vegetation the instant they sense a threat. Their slender build and arboreal habits echo the general body plan seen in many snakes in Minnesota and other temperate colubrids, though the Philippine species tolerate far more humidity and heat.
16. Flying Snake
Despite the name, snakes in the genus Chrysopelea don’t truly fly; they flatten their bodies into a concave, wing-like shape and glide from tree to tree, sometimes covering considerable horizontal distance during a single jump. This gliding behavior helps them move efficiently through the forest canopy without descending to the ground, where predators and prey competition are more intense. Their diet includes lizards, bats, and small birds, captured with a mildly venomous bite that poses no real danger to people. The Philippines shares this genus with much of tropical Asia, making flying snakes a recognizable feature of rainforest snake communities throughout the region.
17. Philippine Pit Viper (Trimeresurus flavomaculatus)
Trimeresurus flavomaculatus is one of several Philippine pit vipers whose venom has drawn increasing scientific interest for its effects on blood clotting rather than just neurotoxicity. The Philippines has a high diversity of venomous snake species, though there is minimal information on their envenomation effects, evidenced by the small number of case reports and the absence of specific antivenoms apart from one against the Philippine cobra. Venom from this species and the related Trimeresurus mcgregori was shown to clot human plasma and isolated human fibrinogen in coagulation studies, a finding with real implications for how bites are treated. Like most pit vipers, it hunts nocturnally using heat-sensing pits between the eye and nostril, a specialized sense also found in rattlesnake species across the Americas.
18. Wagler’s Pit Viper (Tropidolaemus wagleri)
Wagler’s pit viper is arguably the most photogenic venomous snake in the Philippines, sporting vivid green, yellow, or blue coloring depending on sex and region, with females noticeably bulkier than the slender males. People often encourage this beautiful pit viper to live in temples and courtyards, considering its presence a sign of good fortune, a cultural tolerance rarely extended to other venomous snakes. It ambushes prey from low branches, remaining motionless for hours before striking at passing rodents, frogs, or birds. Bites cause significant local swelling and pain, though fatalities are uncommon compared with elapid envenomation.
19. Boiga angulata
Boiga angulata belongs to the cat snake genus, a group of nocturnal, mildly venomous colubrids named for their vertical, cat-like pupils that expand dramatically after dark. This particular species is endemic to the Philippines and tends to favor forest edges and disturbed lowland habitat rather than deep primary forest. Like its cat snake relatives, it hunts small vertebrates using a slow-acting venom delivered through rear fangs, making it a low risk to people who avoid handling it. Its slim, laterally compressed body helps it move confidently along thin branches while searching for sleeping birds and lizards, a foraging style shared with several snakes documented in Iowa’s snake population that similarly raid nests under cover of darkness.
20. Philippine Cat Snake (Boiga philippina)
Boiga philippina is the Philippines’ most widely recognized cat snake, identifiable by a boldly patterned body of dark blotches on a lighter background and those characteristic slit pupils. It is almost entirely nocturnal, spending daylight hours coiled in tree hollows or dense foliage before emerging to hunt geckos, birds, and their eggs after dark. Its rear-fanged venom is potent enough to subdue small prey quickly but is not considered medically significant to healthy adult humans. Homeowners in suburban Luzon occasionally find this snake raiding chicken coops at night, drawn by the same easy prey that also attracts many nocturnal hunters.
21. Gervais’ Worm Snake
Gervais’ worm snake belongs to the blind snake family and shares the same earthworm-like body plan, reduced eyes, and fully subterranean lifestyle as the Brahminy blindsnake described earlier. It is typically placed within the genus Ramphotyphlops, a group whose taxonomy has shifted repeatedly as researchers untangle the many superficially similar blind snake lineages across Southeast Asia. Diet centers on ant and termite larvae, located by chemical cues rather than sight, since the eyes are reduced to little more than dark spots beneath translucent scales. Its total harmlessness to people places it firmly among the least dangerous entries on this list, more curiosity than concern.
22. Philippine Gray-tailed Ratsnake
The Philippine gray-tailed ratsnake is a mid-sized colubrid in the ratsnake group, favoring lowland forest and agricultural edges where rodents are abundant. Its coloring runs from olive-brown to gray along most of the body, with a distinctly duller tail that gives the species its common name and helps distinguish it from more vividly patterned relatives. Like other ratsnakes, it relies purely on constriction to subdue prey and poses no venom risk to people, though it may bite defensively if cornered. Farmers generally welcome its presence since a single adult can account for a meaningful dent in a local rodent population over time.
23. Maren’s Bronzeback Snake
Dendrelaphis marenae is a more recently documented bronzeback species, distinguished from its widespread relatives by subtle differences in scale counts and coloration that took herpetologists years to formally separate. Like other bronzebacks, it is fast, slender, and almost entirely diurnal, foraging through low vegetation for frogs and small lizards during daylight hours. Its restricted known range highlights how much remains to be documented among Philippine colubrids, even in a genus as familiar as Dendrelaphis. Species like this underscore why island-by-island surveys keep turning up previously overlooked snake populations across the archipelago’s more remote islands, much as new surveys periodically refine species lists for snakes in Maine and other well-studied regions.
24. Red-tailed Green Ratsnake
Gonyosoma oxycephalum, the red-tailed green ratsnake, is one of the more strikingly colored non-venomous snakes in the Philippines, combining a vivid green body with an orange or rust-red tail tip. This semi-arboreal, constricting snake hunts rodents and birds, climbing confidently through the mid-canopy in search of nests. Juveniles often display a browner, more mottled pattern that shifts to the adult green coloration as they mature. Despite an intimidating defensive display involving a flattened neck and loud hiss, this species relies purely on bluff and constriction rather than venom.
25. Mountain Smooth-scaled Ratsnake
True to its name, the mountain smooth-scaled ratsnake inhabits cooler, higher-elevation forests where temperatures rarely reach the sweltering lows shared by lowland species on this list. Its scales lack the pronounced keel found in many other Philippine colubrids, giving the body a glossier, smoother appearance under light. This species preys on small rodents and occasionally amphibians, using constriction in the same manner as its lowland ratsnake relatives. Because it favors remote montane forest, encounters with people remain uncommon, and much of its natural history is still poorly documented compared with more accessible lowland species.
26. Paradise Tree Snake
The paradise tree snake, Chrysopelea paradisi, is the most colorful of the Philippines’ gliding snakes, marked with rows of green or turquoise spots along a black body that make it a favorite subject for wildlife photographers. Like its flying snake relatives, it launches from high branches and flattens its ribs outward to slow its fall, steering with subtle body undulations as it glides toward a lower perch. Its diet includes lizards, small birds, and bats snatched during brief, opportunistic pursuits through the canopy. The species is mildly venomous but poses essentially no threat to people, who are far more likely to see one gliding overhead than to be bitten.
27. Philippine Whip Snake
Ahaetulla philippina is the Philippine-endemic member of the whipsnake group, distinguished from the more widespread Oriental whipsnake by subtle differences in scalation and range restricted to the archipelago. It shares the same extraordinarily thin body, horizontally slit pupils, and daytime hunting habits that make whipsnakes such effective ambush predators of tree frogs and lizards. Bites deliver a mild, rear-fanged venom suited to subduing small prey rather than defending against larger animals, including people. This species tends to occupy slightly denser forest interior than its more generalist Oriental relative, making it a less frequent visitor to gardens and farmland in regions with cooler climates by comparison.
28. Philippine Vine Snake
Vine snakes in the genus Ahaetulla take camouflage to an extreme, with a body so slender and a head so pointed that a motionless individual is easy to mistake for an actual vine or twig hanging among the foliage. This resemblance is more than passive; the snake often sways gently to mimic vegetation moving in the wind, closing the distance on unsuspecting lizards before striking. Excellent binocular vision, unusual among snakes, lets it judge distance precisely for what is essentially an ambush hunt from a stationary position. Non-venomous to humans for all practical purposes, it is one of the more harmless entries among the archipelago’s arboreal specialists.
29. Dog-toothed Cat Snake
Boiga cynodon earns its common name from noticeably enlarged front teeth that give the mouth a toothier profile than most other cat snakes in the region. It is one of the larger species in the genus, capable of exceeding two meters, and favors forest edge habitat where it hunts birds, bats, and smaller reptiles after dark. Like other Boiga species, its venom is mild and rear-delivered, built for subduing prey rather than defending against something as large as a person. Its size and boldly blotched pattern occasionally lead to confusion with venomous pit vipers, despite the two groups having little in common beyond superficial coloring.
30. Philippine Yellow-spotted Pitviper
This is another common name applied to Trimeresurus flavomaculatus, the same species profiled earlier in this guide, with “yellow-spotted” referring directly to the pale flecking scattered across its otherwise olive or brown dorsal scales. That pattern provides effective camouflage against lichen-covered bark and leaf litter, letting the snake ambush passing rodents and frogs from a nearly invisible coiled position. As with other Philippine pit vipers, heat-sensing facial pits allow it to strike accurately at warm-blooded prey even in complete darkness. Hikers in Luzon’s forested mountains are advised to watch footing and handholds carefully, since this species’ coloring blends in exceptionally well with the surrounding terrain, a caution echoed by guides covering snakes in Montana‘s own rocky, well-camouflaged species.
31. Keeled Pitviper
“Keeled pitviper” describes several Philippine species in the genus Trimeresurus whose dorsal scales carry a raised ridge, or keel, running down the center of each scale, giving the skin a rough, textured feel rather than the smooth finish seen in many colubrids. This scale structure likely aids in shedding water quickly in the humid montane forests these vipers favor, though its full ecological function remains an open question for researchers. Like its pit viper relatives, it is arboreal, nocturnal, and equipped with heat-sensing facial pits used to locate warm-blooded prey in total darkness. Bites cause localized swelling and pain and should be treated with the same urgency given to any of the country’s venomous pit vipers, a precaution that also applies to keeled species among snakes in Arkansas and similar humid regions.
32. Triangle-spotted Snake (Cyclocorus)
The triangle-spotted snake belongs to Cyclocorus, one of five snake genera found nowhere on Earth outside the Philippines. Cyclocorus lineatus and its relative C. nuchalis have been noted to feed on skinks, eggs, and other snakes, an unusually varied diet for a relatively small, secretive colubrid-like species. This lineage forms part of an entirely endemic Philippine radiation of elapoid snakes that originated between 35 and 25 million years ago, long before many of the archipelago’s islands took their current shape. Its scientific significance far outweighs its size, making it a favorite subject among researchers studying the genus in detail.
33. Stripe-lipped Snake (Hologerrhum)
Hologerrhum philippinum, the stripe-lipped snake, is named for a pale line running along the upper jaw that stands out against otherwise dark coloration. Like its relative Cyclocorus, this genus is restricted entirely to the Philippines and is now classified within the family Cyclocoridae, a lineage recognized only in the last decade as distinct from other colubrid-like snakes. Hologerrhum includes two species and is restricted to islands of the Luzon Pleistocene Aggregate Island Complex, one island of the West Visayan complex, and a single island in the Romblon group. That narrow, island-specific distribution makes habitat loss on any one of those islands a genuine conservation concern for the entire genus.
34. Philippine Burrowing Snake (Oxyrhabdium)
The genus Oxyrhabdium contains two burrowing species built for life beneath leaf litter and loose forest soil rather than out in the open. Oxyrhabdium contains two species, Oxyrhabdium leporinum and O. modestum, occurring across the Luzon, Mindanao, and Western Visayas island complexes, the Babuyan Island Group, and the islands of Camiguin Sur, Lubang, Mindoro, and Siquijor. Their diet leans heavily toward earthworms and soft-bodied invertebrates, a specialization reflected in their narrow, slightly upturned snouts suited to pushing through soil. Like their Cyclocoridae relatives, these snakes are harmless to people and rarely seen except when disturbed during gardening or construction work. Details of the genus’s range come from recent taxonomic research that has reshaped how scientists classify this entire endemic group.
35. Philippine Mountain Snake (Myersophis)
Myersophis alpestris is the only known species in its genus, a rare, poorly studied burrower restricted to high-elevation habitat. The genus Myersophis currently includes a single, poorly known species, making it one of the least-documented snakes anywhere in the Philippines. Nothing is known of the diet for Myersophis alpestris, though researchers estimate it to be an earthworm specialist based on skeletal similarities to Oxyrhabdium. Its rarity in collections and near-total absence from casual sightings reflect both its secretive burrowing lifestyle and the difficulty of surveying the remote mountain forest it calls home.
36. Waray Dwarf Burrowing Snake
Described only in 2020, the Waray dwarf burrowing snake, Levitonius mirus, is a genuine scientific surprise: a miniature burrowing species so distinct that researchers created an entirely new genus to classify it. Levitonius mirus has a maximum total length of just 172 millimeters and is currently the smallest known species in the entire superfamily Elapoidea, a group that also contains cobras, coral snakes, and mambas. Molecular data show Levitonius is most closely related to Myersophis and Oxyrhabdium, sharing multiple skeletal characteristics, and appears to be fossorial with a diet likely specialized on earthworms. It was found only on Samar and Leyte islands, a reminder that even now, new snake species continue turning up in the corners of the Philippine archipelago that researchers have only recently begun to explore in detail.
Thirty-six species barely scratch the surface of what actually lives across more than 7,000 islands, but they cover the groups most people will actually encounter: constrictors, mildly venomous colubrids, medically significant elapids, marine kraits, and the strange, ancient radiation of burrowing snakes found only in this one archipelago. Anyone spending real time outdoors here, whether hiking Luzon’s mountains or diving reefs near Palawan, benefits from learning to tell a harmless bronzeback from a cobra at a glance. For a broader look at how this list fits into the country’s full snake fauna, the overview at Philippine snake species is a useful companion read, and travelers comparing biodiversity across regions may also find it interesting to see how snake diversity here stacks up against places like Kansas or Utah, where far fewer species share the landscape.
