Blue Tongue Skink
Blue-tongued skinks comprise the Australasian genus Tiliqua, which contains some of the largest members of the skink family (Scincidae). They are commonly called blue-tongued lizards or simply blue-tongues or blueys in Australia. As suggested by these common names, a prominent characteristic of the genus is a large blue tongue that can be bared as a bluff warning to potential enemies. The type of predator/threat that is near will determine the intensity of color present in the tongue. In addition, their blue tongue will produce a response in the prey which will in turn diminish the attack. The tongue can also deform itself and produce thick mucus in order to catch prey. They are relatively shy in comparison with other lizards, and also significantly slower due to their shorter legs.
