Overview
Radde's mountain viper is a large, robust member of the mountain viper group inhabiting rugged highlands of the Caucasus region. It shares its scientific name with the Armenian viper, reflecting their shared taxonomic identity as regional common names for the same species.
It is venomous, and though bites are medically significant, the snake's remote rocky habitat means encounters with people are relatively infrequent.
How to identify it
- Light gray to yellowish-brown background with dark, well-defined dorsal blotches arranged in a row
- Thick-bodied, powerful build
- Large, triangular head distinct from the neck
- Vertically elliptical pupils
- Adults typically 60-100 cm long
Best identified by its bold blotched pattern combined with its high-altitude rocky range shared with other Montivipera species.
