ABOUT THIS SPECIES

Blue-tongue skinks are medium terrestrial lizards known for their distinctive bright blue tongue, which is displayed as a defensive signal. They are native to New Guinea, and surrounding islands, inhabiting grasslands, woodlands, and scrublands.

These skinks have stout bodies, short limbs, and smooth overlapping scales, with colouration ranging from brown to grey with banded or blotched patterns depending on the species. They are diurnal and spend much of their time foraging for insects, fruits, and vegetation.

In captivity, Blue-tongue skinks benefit from a well-structured terrestrial setup with hiding spots, moderate humidity, and a basking area to thermoregulate. Their omnivorous diet and calm temperament make them popular among reptile keepers, provided enclosures meet their space and environmental needs.
