There is a definite hierarchy or pecking order within each family. Their diet consists mainly of insects, gum leaves, herbage, and berries. The insects they eat may be found in decaying wood of fallen trees or other debris. The Cunningham's skink may, also, hunt small mammals and frogs. These Skinks may enjoy fruits and flowers as well.
Juveniles eat small crickets, grasshoppers, moths and flies.
In captivity, they may be fed dog food, fruits and vegetables, and whatever insects can be caught. Juveniles may be fed crickets, finely chopped cat food, mashed bananas and apples. The juvenile stage is normally carnivorous, whereas, the adult is omnivorous in nature. The ritual chasing and biting display is an important part of the courting behavior. Gestation is six weeks.
