BLUE-TONQUED SKINK
Cyclodomorphus casuarinus
DESCRIPTION
Blue-tonqued Skink (Cyclodomorphus casuarinus) is a distinctive lizard known for its vibrant blue coloration on the underside of its tongue, which is used as a warning signal to potential predators. This skink typically has a robust body with smooth, shiny scales that can vary in color from brown to gray, providing excellent camouflage in its natural habitat. Behaviorally, it is known to be a ground-dwelling species that prefers to hide under leaf litter or rocks, and it is often seen basking in the sun during the day.
FUN FACTS
