The Nose-horned Viper, also called just Horned Viper and, to distinguish from the Rhinocerous Viper of West Africa, the European
Nose-horned Viper, is native to southern Europe (southern Austria through to Turkey) and also parts of Georgia and Syria.
It is also called the Long-nosed Viper. Some of the regional subspecies are called Sand Vipers.
It likes rocky, scrub or sandy habitats. It is highly venomous and grows to just under a metre (some 37 inches).
Usual prey is mice.
