Great desert skink


The great desert skink, also known commonly as Kintore's egernia, is a species of skink, a lizard in the family Scincidae. The species is endemic to the western half of Australia. It is a burrowing lizard and extremely social.

Etymology

The specific name, kintorei, is in honor of Algernon Keith-Falconer, 9th Earl of Kintore, a British politician who was a colonial governor of South Australia.

Description

The great desert skink is a medium-sized skink, reaching an average snout-to-vent length of 19 cm. It has smooth, small, glossy scales and is mostly rust-coloured on the top of the body, with the belly a vanilla color. It has relatively large circular eyes and a short snout.

Distribution and habitat

L. kintorei is native to the southwestern quarter of the Northern Territory, and dispersed slightly throughout most of Western Australia. As the common name suggests, it is a desert reptile, living in burrows. The burrows can extend up to 12 meters in length, and can have as many as 20 entrances.

Behaviour

Researchers have recently made a stunning discovery with regard to L. kintorei — out of over 5,000 species of lizards documented, this species has been said to have "unique" behavior among them. Individuals of the great desert skink appear to work in cooperation with one another to build and take care of their burrows, even digging out specific rooms for use as a defecatorium. Mates are faithful to one another and always mate with the same lizard, although 40 percent of males have been documented to mate with other females. The tunnels are mostly excavated by adults, while juvenile lizards contribute small "pop" holes to the system. DNA analysis has shown that immature lizards live in the same burrow with their siblings, regardless of age difference. The study, carried out in the Uluru-Kata Tjuta National Park, also revealed that all immature lizards were full siblings in 18 of 24 burrow systems. Researchers have confirmed that the lizards are family-based and keep the juveniles in the tunnel system until they mature.
