Diet: Psammodromus algirus preys mainly on terrestrial arthropods, specifically Orthoptera, Formicidae, Coleoptera, Hemiptera, and Araneae.

Conservation status: Psammodromus algirus is threatened by habitat loss.

 Ppsammodromus algirus commonly reaches a snout-to-vent length (SVL) of about , occasionally 9 cm. The tail is 2–3 times the body length. Dorsal colouration is usually metallic brownish with a pair of conspicuous white or yellowish stripes on both sides.
