Characteristics

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 opportunities and natural shelters.

Behaviour

Primarily diurnal and fossorial species, digging burrows in sand and soil. Territorial and solitary outside breeding season. Excellent digestion capable of storing energy during periods of scarcity.

Reproduction

Oviparous: mating in spring, egg-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 impermeable skin and highly efficient kidneys. Capable of going several months without food by drawing on fat reserves. Communicates through hisses and throat inflations.

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.
