Appearance
The spiny-footed lizard's coloration and the pattern of its spots are extremely variable. As result, zoologists have from time to time classified such variations as separate species.Naming
The following three subspecies are recognized, including the nominotypical subspecies:⤷ ''Acanthodactylus erythrurus atlanticus'' Boulenger, 1918 - Morocco
⤷ ''Acanthodactylus erythrurus belli'' Gray, 1845 - Algeria and Morocco
⤷ ''Acanthodactylus erythrurus erythrurus'' - Iberian Peninsula

Behavior
The spiny-footed lizard, like other members of the genus ''Acanthodactylus'', may defend itself aggressively and bite tenaciously, if one tries to catch it. Individuals are continuously involved in skirmishes with other members of the species and the males strenuously defend the borders of their territories.Habitat
Though the spiny-footed lizard prefers dry and sparsely vegetated regions, it is not restricted to arid terrain, and it is not uncommon to find it in other environments.Reproduction
''A. erythrurus'' is oviparous. The number of eggs in a clutch varies from three to seven. The average total length of a sexually mature adult of the species is 18 to 20 cm .References:
