Description

Tropidolaemus wagleri or Wagler's Pit Viper is an arboreal species living in trees. This species is widely distributed in Thailand, Indonesia, West Malaysia, and the Philippines and inhabits wet areas such as swamps, mangroves and lowland forest. Usually found near water, this species can be identified by their markedly triangular head. A young viper is all green with spots of white and red that are sometimes arranged in pale crossbars and the body colour changes as they mature. An adult female has a black body with yellow cross bands, black post-ocular stripe and banded belly and can grow up to 100cm long while the adult male body is green, with a black border and many greenish yellow crossbars on its back and can grow up to 75 cm long. This species preys on small animals especially birds, frogs, lizards, mice and other rodents. All pit vipers are known to be venomous. However, Wagler's Pit Viper is generally not considered to be aggressive.
