Bush Viper Scientific Name
The bush viper (Atheris squamigera) inhabits Central and Western Africa with a geographic range that extends from Kivu province Kamanyola to the Takamanda Forest Resort in Cameroon.
Other common names for this reptile are variable bush viper, green bush viper, leaf viper, and Hallowell’s green tree viper. Like any viper, a major identification of the species is that venomous toxin.
The bush viper is a venomous reptile in Africa. The snakes typically prefer low and thick flowering bush and rainforests. A solitary creature, the bush viper is arboreal and terrestrial. Their colors make for exceptional camouflage. They blend into their ecosystems and ambush prey.
Bush vipers are predators, sinking their fangs into prey while dangling from a tree limb. The viper’s diet is primarily small mammals and reptiles like lizards, toads, and birds. For the hunt, the bush viper uses two hollow front fangs.
When they bite, prey gets injected with a hemotoxic venom that cripples its defenses. With a weight of between four to eight pounds, the snakes are extremely quick, capable of taking out prey in milliseconds after remaining still for long periods.
These vipers go by many common names that include the African viper, variable bush viper, green viper, tree viper, rough-scaled viper, green bush viper, and leaf viper.
