Viperinae

Viperinae

The Viperinae, or viperines, are a subfamily of venomous vipers found in Europe, Asia and Africa. They are distinguished by their lack of the heat-sensing pit organs that characterize their sister group, the Crotalinae. Currently, 12 genera and 66 species are recognized. Most are tropical and subtropical, although one species, Vipera berus, even occurs within the Arctic Circle.
