About the Nose-horned Viper

Vipera ammodytes, commonly known as horned viper, long-nosed viper, nose-horned viper, and sand viper, is a species of viper found in northern Italy, the Balkans, and parts of Asia Minor. Like all other vipers, it is venomous. It is reputed to be the most dangerous of the European vipers due to its large size, long fangs (up to 13 mm) and high venom toxicity. The specific name, ammodytes, is derived from the Greek words ammos, meaning "sand", and dutes, meaning "burrower" or "diver", despite its preference for rocky habitats. Five subspecies are currently recognized, including the nominate subspecies described here.

V. ammodytes grows to an average total length (snout-tail) of 85 cm (33.5 in), although individuals usually measure less than 75 cm (29.5 in). Maximum length also depends on locality, with northern forms distinctly larger than southern ones. In one field study on Golem Grad island (in North Macedonia), for example, females averaged 35 cm., and males at 37 cm.; the largest captured during the study was a male, at 66 cm. long. This indicates some degree of regional or insular dwarfism.
