Asp Viper

The Asp Viper is a European viper found predominantly in France, Italy, Switzerland, and parts of Spain and Germany. It is closely related to the Common Adder but is generally regarded as having somewhat more potent venom.

It is venomous and bites can require medical attention, though fatalities are rare in areas with modern healthcare access. It is a well-known component of European herpetofauna, occupying much of the same range historically associated with folklore about vipers.

• Stout body with strongly keeled scales
• Coloration variable, typically gray, brown, or reddish with a dark, often broken or blotched zigzag pattern
• Snout tip is often slightly upturned, a feature that can help distinguish it from other European vipers
• Broad triangular head distinct from the neck
• Vertical elliptical pupils
• Adults typically 0.5-0.75 m

Found in dry, rocky, sunny habitats including hillsides, vineyards, forest clearings, and stone walls across France, Italy, Switzerland, and parts of Spain and Germany, from lowlands to subalpine elevations.

Diurnal, often seen basking on rocks or stone walls in sunny weather. Feeds on small mammals, lizards, and occasionally birds. Generally retiring but can be defensive if disturbed. Reproduction is viviparous, with females giving birth to litters typically of 5-15 young.
