|Cunningham's skink basking in the sunlight|
Cunningham's skink has a distinctive keel on each scale, which gives it a slightly spiny appearance. It is extremely variable in colour, ranging from dark brown to black, with or without blotchy patches, speckles, or narrow bands.
E. cunninghami prefers to live communally in the crevices of rocky outcrops or hollow logs.
Cunningham's skink 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 E. cunninghami is viviparous, giving birth to six or more live young in a litter.
Habitat fragmentation can affect a species population by disrupting core processes. One such process is inbreeding avoidance (avoiding inbreeding depression). The impact of habitat alteration (deforestation) on inbreeding was studied in the rock-dwelling Australian lizard Egernia cunninghami. Such populations in deforested areas experience potentially inbreeding-enhancing factors such as reduced dispersal and increased relatedness. However, active avoidance of close kin as mates was observed, as indicated by the substantially lower relatedness in actual breeding pairs compared to potential ones expected if there were random mating. This finding, as well as heterozygous excesses in immature lizards from disturbed (as well as undisturbed) habitats indicted that E. cunninghami maintains outbreeding in the face of increased accumulation of relatives.
