The black rock skink (Egernia saxatilis) is a species of large skink native to Eastern and Southern Australia from central New South Wales to Grampians National Park in Victoria. A large, dark colored skink, up to 135 mm from snout to base of the tail, the black rock skink is the first reptile discovered to have a "nuclear family" structure where the parents form a pair and care for their offspring for more than one year. The black rock skink is a viviparous skink meaning females give birth to live offspring instead of laying eggs. They defend their home range and families against conspecifics for up to several years.
