Eryx somalicus, known commonly as the Somali sand boa, is a species of small snake in the Boidae family.

The basic colour of the dorsal surface is some shade of brown with about thirty transverse or semi-oblique whitish bands, sometimes with dark margins.

[4] The Somali sand boa is endemic to Somalia and possibly occurs in neighbouring areas of eastern Ethiopia.

They mostly hide by day under stones, in crevices or in shallow burrows, but may emerge onto the surface in overcast conditions.

They feed on mammals, lizards and birds, usually lying in wait hidden in the sand with just their eyes and snout above the surface.
