Vipera

Genus of snakes

Vipera is a genus of snakes in the subfamily Viperinae of the family Viperidae. The genus has a very wide range, being found from North Africa to just within the Arctic Circle, and from Great Britain to Pacific Asia. The Latin name vīpera is possibly derived from the Latin words vivus and pario, meaning "alive" and "bear" or "bring forth"; likely a reference to the fact that most vipers bear live young. 21 species are recognized as being valid. Like all other vipers, the members of this genus are venomous.
