Spanish psammodromus

The Spanish psammodromus, scientifically known as Psammodromus hispanicus, is a diminutive lizard belonging to the Lacertidae family. Its name derives from Greek roots meaning 'sand' and 'to run,' with 'hispanicus' indicating its Spanish origin. This species is notable for its slender, long-bodied form, small pointed head, and a strikingly long, slender tail that can be about 1.5 times its body length. Its scales are keeled and overlapping, giving it a characteristically rough texture. The coloration typically ranges from dark brown to olive-brown or dark red, often adorned with irregular lighter blotches and streaks, while its underside is a pale yellow.

Habitat and Distribution

Found primarily across the Iberian Peninsula, with the exception of the northern coast and the Pyrenees, the Spanish psammodromus also extends its range along the Mediterranean coast of France. Its preferred natural habitats are dry, open Mediterranean environments, including shrubland, temperate grasslands, sandy shores, and even arable land, pastureland, and rural gardens. They can be found at elevations up to 1500 meters, often favoring areas with stone cover and loose, sandy soil.

Biology and Behavior

Spanish psammodromus are diurnal, meaning they are active during the day. Their diet consists mainly of small insects and spiders. When threatened, their primary defense mechanism is to flee rapidly into nearby vegetation. If captured, they may emit a squeaking sound but are not known to bite. Breeding commences in the spring following their hibernation. Females lay clutches of 2 to 8 eggs in warm, moist locations, such as under hay piles or in rotting wood. These eggs typically incubate for around 8 weeks, and females may lay up to two clutches per breeding season. The average lifespan for this species is quite short, usually between 2 to 3 years, with many individuals succumbing after their first mating season. They reach sexual maturity within their first year of life.
