Animal’s Behaviour

The Orange-Eyed Crocodile Skink is a species of terrestrial, semi-aquatic skink. They are a shy, crepuscular species – most active at dawn and dusk – and spend the rest of their time burrowed or well hidden under leaf litter or in hides. They are fast runners; good climbers and very efficient swimmers who are known to soak in water.  They are able to regenerate their tails if severed in an attack. Females have two ovaries but only the right oviduct and produce only a single egg at a time. The egg is large and the young are comparatively large at hatching. The Crocodile Skink has the distinction of being the only species of lizard known to vocalize when in distress, startled or in defense of offspring.  Juveniles will play dead if captured. The Crocodile skink was largely unknown in captivity until 1994.
