Acanthodactylus is a genus of lacertidlizards, commonly referred to as fringe-fingered lizards, fringe-toed lizards (though the latter common name is also used for the New World lizard genus Uma), and spiny-toed lizards.
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.[citation needed]
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.[citation needed]
Behavior
Every saurian of the genus Acanthodactylus is very aggressive and gets continuously involved in skirmishes with other members of its species.[citation needed] The males strenuously defend the borders of their territories.[citation needed]
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).[citation needed]
