Snake-tailed fringe-toed lizard description

KingdomAnimalia
PhylumChordata
ClassReptilia
OrderSquamata
FamilyLacertidae
GenusAcanthodactylus (1)

Owing to its superficial similarity to its larger congener, Acanthodactylus boskianus, the snake-tailed fringe-toed lizard was only officially described in 1980 (2). As its name suggests, this species has a particularly long tail (3), and, in common with other Acanthodactylus species, the toes are fringed with scales adapted for running over loose sand (4) (5). Like other lacertids, the body is long and cylindrical, and the legs are well developed (4). The basic body colour is grey, with seven dark stripes running down the back and sides (2), and a tail tinged red in immatures (3).

Also known as
Arnold’s fringe-fingered lizard.

Snake-tailed fringe-toed lizard biology

There is very little information available on the biology of the snake-tailed fringe-toed lizard. However, this diurnal lizard reportedly lives in burrows excavated out of hard sand. Remaining concealed for all but a few hours of the day, the burrows not only act as a shelter from predators but also provide refuge from extreme temperatures (6).
