Blue tongue skinks are a genus of diurnal, terrestrial lizard found throughout Australia and parts of Indonesia. All Tiliqua species can be easily recognized by their triangular heads, heavy torpedo-shaped bodies, short legs, and distinctive blue tongue.
Most subspecies of blue tongue skink have a blue or bluish tongue. This unique color reflects UVA light, which blue tongue skinks can see, but humans can't!
