Borneo is home to countless reptiles. Numerous species of lizards, crocodiles, fresh and salt water turtles, tortoises, snakes and frogs to name but a few. Some of the more famous of the 160 species of snake include the reticulated python, arguably the largest snake in the world with individuals found up to 30ft long. Of the venomous snakes the King Cobra, the longest venomous snake in the world, his cousin the Common or Malay cobra and a large group of pit vipers are numerous in Borneo, although hard to find. The more frequent encounters with reptiles in Borneo occur in lesser populated areas, in the large, sparsely inhabited rivers like the Kinabatangan and the Klias salt water crocodiles can still be found. (

  • Invertebrates


Dwarfing any other animal group in sheer number of species and population sizes, Borneo’s invertebrate species have successfully adapted to the island’s tropical rainforest habitats.

Just one tree in Borneo’s lowland forests was found to contain more than 1,007 species of arthropods. Of the arthropods, Hymenoptera (sawflies, wasps, bees, and ants), Coleoptera (beetles), flies (Diptera) and true bugs (Hemiptera) show the most species and largest population sizes. (WWF)
