Overview
Darevsky's Viper is a small member of the true adder group found in isolated highland meadows of the southern Caucasus. It is named after herpetologist Ilya Darevsky and is one of the rarest European vipers.
Its extremely restricted, fragmented range in volcanic upland habitat places it among the most threatened viper species, with ongoing habitat conversion posing a significant risk.
