Key identifying features
The Algerian Whip Snake (Hemorrhois algirus) is recognized by its slender body typical of whip snakes, combined with a pattern of dark spots, bars, or blotches along a paler background, which can vary considerably between individuals and populations.
Coloration & pattern
The dorsal ground color ranges from pale gray or tan to yellowish-brown, marked with a series of dark brown to blackish spots or short bars that may be more distinct toward the front of the body and less defined toward the tail. Some individuals show a relatively bold, contrasting pattern, while others appear more subdued. The belly is generally pale, sometimes with a light checkered pattern.
Head, eyes & scales
The head is narrow and not strongly distinct from the neck, with large eyes and round pupils characteristic of active, diurnal colubrids. Scales are smooth, giving the body a glossy finish that highlights the contrasting pattern.
Size & body shape
Adults are typically slender and moderately long, consistent with the fast-moving whip snake body plan, with a long tail contributing to overall length and agility.
Range & habitat where you'll see it
The Algerian Whip Snake is found across North Africa, including Algeria and neighboring regions, in dry, open habitats such as rocky terrain, scrubland, and semi-desert edges, often near human settlements and stone structures.
How to tell it apart from look-alikes
Its pattern of dark spots or bars on a pale background, combined with a slender body, helps distinguish it from more uniformly colored whip snakes such as the Black Whip Snake. Compared to the Horseshoe Whip Snake, which also shows blotching, the Algerian Whip Snake typically lacks the diagnostic horseshoe-shaped head marking. Attention to the specific pattern of markings along the body, along with North African range, helps confirm identification.
