Indicative values: they vary by subspecies, sex and region.

Habitat and distribution

Arid and semi-arid environments: deserts, steppes, rocky and sandy areas with sparse vegetation. Prefers areas offering digging possibilities and natural shelters.

Behaviour

Mainly diurnal and burrowing species, digging burrows in sand and earth. Territorial and solitary outside the breeding season. Excellent digestion capable of storing energy during periods of scarcity.

Reproduction

Oviparous: mating in spring, laying of 4 to 30 eggs in summer in burrows or protected cavities. Natural incubation of 4 to 5 months depending on environmental temperature.

Peculiarities

Exceptionally resistant to dehydration thanks to waterproof skin and highly efficient kidneys. Able to go several months without eating by drawing on its adipose reserves. Communicates by whistling and throat puffing.

Threats and conservation

Currently stable species. Although locally captured for the pet trade and hunted for meat, these pressures remain moderate and the species maintains viable populations.
