Very little information is available on the biology of the leopard skink (2).
Ctenotusspecies are known to be active solely during the day time, but the leopard skink is unusual within its genus as it also remains active at night to forage. This remarkable behaviour is believed to be due to its dietary preference for termites, which are nocturnal and occur in higher numbers in the cooler temperatures of the evening (4) (8). Between 70 and 90 percent of this species’ invertebrate diet is made up of the water-rich insect, and the leopard skink’s ability to exploit this food source by adapting to the constraints of low night-time temperatures also lowers the risk of predation by birds. Although this species remains more active during the day time when temperatures are high, foraging primarily takes place at night (4).
Ctenotus skinks respond rapidly when disturbed, retreating quickly from the source into a burrow, if available. Many skink species are able to shed their tails as an escape mechanism from predators, and it is possible that the leopard skink also displays this behaviour when captured. Skinks are oviparous, laying eggs instead of giving birth to live young (9).
