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 simplyblue-tongues 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. Blue tongue skinks belong to the genus Tiliqua, in which they comprise a number of species and sub-species. These animals are found in the wild throughout much of New Guinea and Australia. While animals are still exported from their countries of origin in New Guinea, all blue tongue skins of Australian origin are captive bred, mostly in the United States, Europe, and Japan. In nature, blue tongue skinks are found in a wide variety of habitats. Animals hailing from AustraliaÍs interior deserts are adapted to a harsh desert lifestyle, while those species from more northern ranges are used to a more tropical environment. These animals get their common name from the bright blue tongues that they possess and display when startled or during territorial disputes. As pets, they rank high on the list as a result of their gentile demeanor, appearance, and ease of care.
