Overview

The Nose-Horned Viper is widely regarded as the most dangerous and most venomous snake in Europe due to its relatively large size, potent venom, and frequent proximity to humans in rocky Balkan terrain.

It is instantly recognizable by the small, soft, upturned scale at the tip of its snout, unique among European vipers.

How to identify it

  • Medium-sized, robust viper with a soft, fleshy horn on the snout tip
  • Grey, brown, or reddish background with a dark zigzag dorsal band
  • Distinct triangular head clearly set off from a narrow neck
  • Vertical, cat-like pupils
  • The nasal horn readily separates it from other European vipers such as the Adder or Meadow Viper

Behavior, diet & reproduction
