Harran fringe-toed lizard
The Harran fringe-toed lizard (Acanthodactylus harranensis) is a critically endangered lizard species endemic to southeastern Anatolia, specifically known from the ancient ruins of Harran, Turkey. It is characterized by its relatively large, stout body, a tail longer than its body, and distinctive dorsal stripes or spots. This species inhabits rocky areas with sparse steppe vegetation and is threatened by increasing tourism and habitat degradation.

About Harran fringe-toed lizard
The Harran fringe-toed lizard, scientifically known as Acanthodactylus harranensis, is a species of lizard belonging to the family Lacertidae. It is endemic to southeastern Anatolia, with its known range exclusively within the ruins of the ancient city of Harran in Turkey. This species was formally described in 2005 and takes its name from its type locality.
Description and Habitat
This lizard is characterized by its relatively large and stout body, measuring between 76.5 to 94.8 mm in snout-to-vent length. Its tail is notably long, exceeding 1.5 times its body length. The dorsal coloration typically features irregular longitudinal dark and light stripes, though juveniles may display a pattern of spots. The Harran fringe-toed lizard inhabits rocky environments, including the ancient university ruins at Harran, where the terrain consists of hardened grey sand interspersed with sedimentary rock and sparse steppe vegetation. They are often observed running on the ground or taking refuge within the roots of plants like Peganum harmala, at elevations around 400 meters.
Ecology and Conservation Concerns
The Harran fringe-toed lizard is oviparous, meaning it reproduces by laying eggs. Unfortunately, the species is facing significant threats and is listed as Critically Endangered on the IUCN Red List. Its extremely small total range, estimated at just 3.6 square kilometers, combined with ongoing habitat degradation, makes it highly vulnerable. Major threats include rising tourism, continued archaeological excavations at the ancient site, and overgrazing, which collectively impact its limited habitat. Population estimates suggest fewer than 1,000 adult lizards currently inhabit the ruins.
