Blue Tongue Skink

Tiliqua scincoides

Blue tongue skinks are chunky, personable lizards known for their distinctive bright blue tongue used as a startling defense display against predators. This species complex includes several subspecies from Australia and Indonesia, each with different care requirements - particularly regarding humidity. Northern blue tongue skinks from Australia prefer drier conditions around 30-40% humidity, while Indonesian species like Merauke and Irian Jaya require higher humidity at 60-80%. These robust lizards have smooth scales, stumpy legs, and expressive faces that give them almost dog-like charm and personality. Blue tongue skinks are excellent handleable pets that tolerate interaction well once tame, though they may huff, hiss, and display their blue tongue when initially startled.
