About Blue-throated keeled lizard

The Blue-Throated Keeled Lizard

The blue-throated keeled lizard, scientifically known as Algyroides nigropunctatus and sometimes referred to as the Dalmatian algyroides, is a distinctive species of lizard found within the Lacertidae family. This lizard is notable for its characteristic keeled, V-shaped scales that adorn its flanks, tail, and back, setting it apart from many other lizard species. Males are particularly striking during the breeding season due to their vibrant blue throats, a feature that is less pronounced or absent in females.

Distribution and Habitat

This species is naturally distributed across Italy and the Balkan Peninsula. Its adaptability allows it to inhabit a diverse range of environments. Preferred natural habitats include Mediterranean-type shrubby vegetation, rocky outcrops, and open fields. Additionally, the blue-throated keeled lizard has successfully adapted to human-modified landscapes, being found in arable land, pasturelands, plantations, rural gardens, and even urban areas, demonstrating a degree of resilience in its ecological niche.

Physical Characteristics and Behavior

Adult blue-throated keeled lizards can reach a total length of up to 25 cm (9.8 inches), making them relatively large compared to other members of the Algyroides genus. The body color typically ranges from light brown to rusty brown, complemented by a white to yellowish belly. A defining feature are the rows of black dots present on the back, though these may be less prominent in females outside the mating period. These lizards exhibit a preference for climbing and are generally easily frightened, which contributes to their infrequent presence in captivity, partly due to their protected status.

Diet and Reproduction

The diet of the blue-throated keeled lizard consists of insects, worms, and other small invertebrates, which they actively forage for within their varied habitats. Reproduction involves the laying of two to four eggs, with evidence suggesting that females may be capable of producing eggs in both early spring and early autumn. A notable behavioral aspect during mating is the male's tendency to bite and hold onto the female's neck, a behavior observed in other Algyroides species.
