Vipera ammodytes
species of reptile

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.
Description
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.
The public source identifies “Vipera ammodytes” as species of reptile. This brief keeps that definition visible, then builds a research path around Vipera, ammodytes and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Vipera ammodytes”, the useful work is to connect “species of reptile” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q583923. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
