Scelarcis perspicillata

The Moroccan rock lizard, scientifically known as Scelarcis perspicillata, is a species of lizard belonging to the Lacertidae family. Its precise taxonomic placement has seen it assigned to various genera over time, including Teira, Podarcis, Lacerta, and its current classification within Scelarcis. This agile reptile is native to northwestern Africa, predominantly found in Morocco and Algeria, and has also established an introduced population on the island of Menorca in Spain, where it was first recorded in 1928.

Description and Habitat

Scelarcis perspicillata is characterized by its medium size and a rather flattened body, typically reaching a snout-to-vent length of about 6 cm, with a tail that is roughly 1.7 times its body length. Its coloration exhibits variation across its range; individuals in Morocco are often greyish-brown, frequently featuring two broad, pale stripes along the back. In contrast, those found in Menorca tend to be buff, grey, or greyish-green, densely covered with dark, net-like markings. A distinctive feature across all populations is the presence of a transparent 'window' in the lower eyelid, which aids in identification. The tail is notably fragile and is often a striking bluish color, particularly in younger specimens. The underparts are typically white or bluish. Occasional entirely dark individuals have also been documented.

The natural habitats of the Moroccan rock lizard are diverse, encompassing Mediterranean-type shrubby vegetation, rocky terrains, and coastal areas. They have also demonstrated a remarkable ability to adapt to urban environments, where they can be found on walls, cliffs, boulders, and around human structures. Their agility allows them to readily climb and navigate these varied landscapes.

Behavior and Reproduction

Behaviorally, Scelarcis perspicillata is an active species, frequently observed climbing on various surfaces such as rocks, walls, cliffs, boulders, and even tree trunks. They forage both on the ground and on rocky outcrops. The fragility of their tails is a notable trait, with individuals often found possessing regenerating tails. Reproduction involves females laying small clutches, typically consisting of one to three eggs. These eggs are relatively small, measuring between 12 to 17 mm in length and 6 to 8 mm in width.

While detailed information regarding their lifespan, diet specifics beyond foraging habits, and natural predators is not extensively detailed in historical accounts, their presence in varied natural and human-altered landscapes highlights their adaptability. The species is not considered venomous.
