vipera aspis atra-sottospecie del sopraceneri

Vipera aspis atra is a venomous viper subspecies found in France, Switzerland and Italy.

The Viperidae are a family of venomous snakes found all over the world, except in Antarctica, Australia, Ireland, Madagascar, Hawaii, various other isolated islands, and above the Arctic Circle. All have relatively long, hinged fangs that permit deep penetration and injection of venom. Four subfamilies are currently recognized. They are commonly known as vipers or viperids.
