Discover the Incredible Snakes of Sabah

Sabah is a paradise for wildlife enthusiasts, home to an extraordinary diversity of snakes found nowhere else on Earth. From massive constrictors and brilliantly coloured pit vipers to elusive mountain species and marine snakes, Sabah’s rainforests, rivers, and coastal waters provide some of the best opportunities in Southeast Asia to observe these fascinating reptiles in their natural habitat.

Whether you’re joining a guided night walk, trekking through Kinabalu Park, or exploring Sabah’s lowland rainforests, here are some of the remarkable snakes you may encounter.

🐍 Venomous Species

Sabah is home to several venomous snakes that have adapted to different habitats, from rainforest canopies to mountain forests.

• Sabah Pit Viper (Trimeresurus sabahi)
  Endemic to northern Borneo, this striking bright green pit viper is commonly found in Sabah’s hilly and mountainous forests. It is easily recognised by its vivid red or orange eyes, and spends much of its time resting among vegetation.
• Malcolm’s Pit Viper (Trimeresurus malcolmi)
  One of Borneo’s most sought-after pit vipers, this beautiful species inhabits cool, mossy forests at higher elevations, particularly around Mount Kinabalu. The Malcolm’s pit viper has a predominantly bright emerald to neon-green body often accented by a thin black stripes along its body that provides excellent camouflage among the montane forest vegetation.
• Bornean Keeled Pit Viper (Tropidolaemus subannulatus)
  One of Sabah’s most distinctive venomous snakes, this species displays remarkable sexual dimorphism. Females are much larger with bold black-and-yellow bands, while males are slender with bright green bodies marked by red and white stripes.
• Kinabalu Red-headed Krait (Bungarus flaviceps baluensis)
  A rare montane subspecies of the Red-headed Krait found around Kinabalu. With its vivid red, banded body contrasting against a glossy black body, it is among Sabah’s most striking venomous snakes and can reach up to 1.5 metres in length.

🌿 Non-Venomous Species

Not all of Sabah’s spectacular snakes rely on venom. Many harmless species use camouflage, speed, or constriction to capture their prey.

• Sabah Mountain Slender Slug Snake (Asthenodipsas jamilinaisi)
  Described only recently, this harmless snail-eating snake is frequently documented around Kinabalu Park Headquarters. It is specially adapted to Sabah’s cool montane forests and is a favourite among herpetologists.
• Reticulated Python (Malayopython reticulatus)
  The world’s longest snake species, the reticulated python can grow over six metres long. This powerful constrictor inhabits forests, wetlands, and even rural plantations throughout Sabah.
• Red-tailed Green Ratsnake (Gonyosoma oxycephalum)
  An agile tree-dwelling snake that hunts birds, bats, and lizards high in the canopy. Its colour ranges from brilliant green to yellowish-green, while its distinctive reddish tail gives the species its common name. (But if you ask me, the tail looks more brown than red.)
• Sunbeam Snake (Xenopeltis unicolor)
  This secretive burrowing snake is famous for its iridescent scales, which shimmer with rainbow colours when illuminated by lights. Despite its striking appearance, it is completely harmless to humans.
• Painted Mock Viper (Psammodynastes pictus)
  Often encountered during guided night walks, this small snake mimics the triangular head and defensive behaviour of true vipers. It is rear-fanged and mildly venomous, but its venom is not considered medically significant to humans.

🌊 Marine Snakes

Sabah’s coastal waters are also home to several species of sea snakes, particularly around coral reefs and islands such as Sipadan and Pulau Tiga.

• Yellow-lipped Sea Krait (Laticauda colubrina)
  One of the most recognisable sea snakes, the banded sea krait alternates between land and sea. It is highly venomous but generally docile and rarely aggressive toward divers.
• Olive Sea Snake (Aipysurus laevis)
  A fully marine species commonly found around coral reefs. It is an excellent swimmer and feeds mainly on fish and eels.

Tips for Wildlife Enthusiasts

If you’d like to experience Sabah’s incredible snake diversity, consider joining a guided wildlife or herping tour led by a certified local guide. Night walks in Kinabalu Park, the Danum Valley Conservation Area, the Kinabatangan floodplain, and the Crocker Range are among the best places to spot these remarkable reptiles safely.

Remember to admire snakes from a respectful distance, never attempt to handle them, and avoid disturbing wildlife.
