Contents

[edit] Description

Attains an average length of 76 cm, with females being larger than males. Occasionally, they may grow as large as 91 cm.[2] This is the only Asian pit viper with large crown scales and smooth dorsal scales.[5]

[edit] Geographic range

Found in Thailand, Cambodia, Laos, Vietnam, northern West Malaysia and on the Indonesian island of Java. The type locality is listed as "Java."[1]

[edit] Habitat

Prefers coastal forests, bamboo thickets, unused and overgrown farmland, as well as forests around plantations.[2]

[edit] Reproduction

This species is oviparous and the eggs are guarded by the female after deposition.[5]

[edit] Venom

This species has a reputation for being bad-tempered and quick to strike. In northern Malaysia it is responsible for some 700 incidents of snakebite annually with a mortality rate of about 2 percent. Remarkably sedentary, it has often been found in the same spot several hours after an accident.[5]
