Overview
The Persian ratsnake is a small to medium colubrid closely related to the Aesculapian and Italian ratsnakes, all placed in the genus Zamenis. It is restricted mainly to forested and shrubby habitats around the southern Caspian Sea.
It is a shy, harmless species to humans and is not medically significant. Its inconspicuous coloration and secretive habits mean it is more often encountered by researchers and reptile enthusiasts than by the general public.

- Base color olive-brown to grayish-tan
- A broken or dashed dark line running down the center of the back, sometimes reduced to a series of spots
- Pale, unmarked underside

Diurnal and largely terrestrial, though capable of climbing into low shrubs. It is a calm species that relies on flight rather than aggression when disturbed.
