Mosor rock lizard

The Mosor rock lizard (Dinarolacerta mosorensis) is a flattened lizard characterized by a long head and slender tail, typically reaching about 7 cm in snout-to-vent length. Its dorsal surface is brown, greyish-brown, or olive-brown with dark mottling, while its underparts are unspotted and yellow or orange in adults. This species inhabits high-rainfall limestone outcrops and karst regions above the treeline in southern Croatia, Bosnia and Herzegovina, and Montenegro.

Key Facts

  • The Mosor rock lizard has a flattened body with a long head and slender tail.
  • Adults measure approximately 7 cm in snout-to-vent length, with a tail about twice that length.
  • Its dorsal coloration is brown to olive-brown, often with darker mottling, and its underparts are typically yellow or orange.
  • The species is found in high-rainfall areas, typically on limestone outcrops and karst regions above the treeline.
  • Females lay a single clutch of about four eggs annually.
  • Its conservation status is assessed as 'vulnerable' due to habitat decline.

About Mosor rock lizard

The Mosor Rock Lizard

The Mosor rock lizard, scientifically known as Dinarolacerta mosorensis, is a species of lizard belonging to the Lacertidae family. This reptile is recognized for its flattened body, characterized by a long head and a slender tail which is roughly twice the length of its body. Adults typically measure around 7 centimeters in snout-to-vent length. Its dorsal coloration varies from brown to olive-brown, often adorned with darker mottling and speckling, while its underparts are generally unspotted and present as yellow or orange in mature individuals.

Habitat and Distribution

This lizard species is primarily found in the high-rainfall regions of southern Croatia, Bosnia and Herzegovina, and Montenegro. Its preferred habitat consists of limestone outcrops and karst landscapes situated above the treeline, though it also inhabits juniper-clad slopes, open woodlands, and areas surrounding springs. The Mosor rock lizard is typically found at elevations ranging from 450 to 1,900 meters.

Reproduction and Conservation

Female Mosor rock lizards lay a single clutch of approximately four eggs per year. These eggs are retained within the female for about five weeks post-mating and hatch approximately two and a half weeks later. Juveniles are quite small upon hatching, measuring less than 3 centimeters. The Mosor rock lizard faces threats, notably from logging which contributes to the decline of its habitat. Consequently, its total area of occupancy is less than 2,000 square kilometers, and it is generally uncommon within its range. The International Union for Conservation of Nature (IUCN) has assessed its conservation status as 'vulnerable'.
