How to Identify the Transcaucasian Sand Viper (Identification Guide)

Key identifying features

The Transcaucasian Sand Viper is identified by its sandy to pale brown coloration, a distinctive upturned or slightly raised snout tip, a broad triangular head clearly wider than the neck, and rough keeled scales suited to arid, sandy habitats.

Coloration & pattern

The base color typically ranges from pale sandy tan to light gray-brown, closely matching desert and semi-arid substrates. A row of darker, often irregular blotches or a wavy dorsal stripe runs along the back, providing camouflage against sand and sparse vegetation. The coloration overall tends to be lighter and less contrasted than in forest-dwelling relatives.

Head, eyes & scales

The head is broad and triangular, clearly distinct from the neck, a typical viper trait. A notable feature is the slightly upturned snout, which can appear raised or pointed at the tip. Eyes have vertically elliptical pupils. Scales are keeled, giving a rough surface texture that aids in blending with sandy terrain.

Size & body shape

This is a moderately stout snake for its length, with a body shape adapted to burrowing and moving through loose sandy substrates, and a short tail that tapers quickly.

Range & habitat where you'll see it

Found in arid and semi-arid regions of the Transcaucasus, this species favors sandy plains, dry steppe, and sparsely vegetated desert edges, often partially burrowing into loose substrate.

How to tell it apart from look-alikes

The upturned snout combined with pale sandy coloration helps distinguish this species from other regional vipers that tend to have more contrasted patterns or lack the raised snout feature. Broad triangular head shape and keeled scales further separate it from nonvenomous snakes in the same arid habitats.
