Description
The Centralian blue-tongue is of a very robust build, short body and slender tail, and is among the largest 1% of species in the family Scincidae. Both the forelimb and hindlimb have five digits.Colouring
The skink is predominantly pale brown to grey in colour with a series of nine or more orange-brown bands along the length of the body and tail. These darker coloured bands are much wider than the paler grey-brown interspaces but are at their narrowest along the mid-dorsal region of the skink. There is a distinguishing black stripe surrounding the eye and extending to just above the ear, and upper-hind areas of limbs are also black. The skink is pale cream to white on the underside.Distribution
The geographical distribution of the blue-tongued skink lies throughout the far north-west corner of New South Wales and South Australia, and centrally throughout Western Australia, the Northern Territory and Queensland. In general, habitats include a variety of arid and semi-arid stony and red sandy spinifex vegetated areas.Behaviour
Like many other reptilian species, the blue-tongued is a fairly sedentary terrestrial creature. It is a ground-dwelling, diurnal species and displacements are relatively short (less than 20 metres) and on average the total distance travelled each day can fall between 122 and 245 metres.Diet
Analyses of stomach contents have shown that the blue-tongue feeds on a combination of seeds, insects, livestock dung and some vertebrate and invertebrate material such as that of bird or other reptilian remains (i.e. fragments of bone, loose feathers).Reproduction
Along with the other five species of the same genus, the Centralian blue-tongued skink is a viviparous species – it bears between two and 10 live young in a single litter.Threats
The geographical location of the skink sees one of its major threats to be ingestion of the invasive and toxic cane toad, but it is also under pressures from other anthropogenic processes such as fire and habitat fragmentation. However, the species is still currently listed as least concern.References
