They have a distinctive keel on each scale, which gives them a slightly spiny appearance. Extremely variable in colour ranging from dark brown to black, with or without blotchy patches, speckles or narrow bands.
It prefers to live communally in the crevices of rocky outcrops or hollow logs. It is a diurnal omnivore with its diet including insects, flowers, berries, fungi, leaves and young shoots. There is currently research being done on the isolated population that inhabits the southern Mount Lofty Ranges in South Australia. This population is considered vulnerable due to the fragmented (disjunct) distribution of the 'colonies'. There is evidence that at least one of these colonies has totally disappeared. It is more common within suitable habitat along the southeastern coast and ranges of Australia.
Like some other reptiles the species it is viviparous, giving birth to six or more live young in a litter.
