Geographic range

The approximately 40 species in the genus Acanthodactylus are native to a wide area in North Africa, southern Europe and Western Asia; across the Sahara Desert, to the Iberian Peninsula, and east through the Arabian Peninsula, to Afghanistan and western India.[2]

Habitat

Though lizards of the genus Acanthodactylus prefer dry and sparsely vegetated regions, they are not strictly tied to an arid terrain; so it is not uncommon to come across them in various environments.

Description

Members of the genus Acanthodactylus possess the following combination of traits:[2]

The coloration and pattern of spots of Acanthodactylus is extremely variable, so it is unsurprising that zoologists have, at one time or another, classified every variety as a separate species.

Behavior

Every saurian of the genus Acanthodactylus is very aggressive and gets continuously involved in skirmishes with other members of its species. The males strenuously defend the borders of their territories.

Reproduction

Acanthodactylus are oviparous. The number of eggs in a clutch ranges from 3 to 7. The total length of a sexually mature adult of the genus is, on average, 18 to 20 cm (7.1 to 7.9 in).

Classification

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Acanthodactylus.
