The Armadillo Lizard is a lizard endemic to desert areas of southern Africa. The natural habitat of this lizard is scrub and rocky outcrops. It is diurnal. It hides in rock cracks and crevices. It lives in social groups of up to 30.
The Armadillo Lizard possesses an uncommon antipredator adaptation, in which it takes its tail in its mouth and rolls into a ball when frightened.
Males are territorial, protecting a territory and mating with the females living there. The female gives birth to one or two live young; the species is one of the few lizards that does not lay eggs. The female may even feed her young, which is also unusual for a lizard.
It can live up to 25 years in captivity, or slightly more in rarer cases.
