Shingleback

Tiliqua rugosa, most commonly known as the shingleback skink, shingleback lizard, bobtail lizard, and the two-headed skink (often simply shingleback or bobtail); is a short-tailed, slow-moving species of blue-tongued skink (genus Tiliqua) endemic to Australia. Three of its four recognised subspecies are found in Western Australia, where the bobtail name is most frequently used. The fourth subspecies, T. rugosa asper, is the only one native to eastern Australia, where it goes by the common name of the eastern shingleback. Apart from bobtail and shingleback, a variety of other common names are used in different states, including two-headed skink, stumpy lizard, stumpy-tailed lizard, pinecone lizard, bogeye or boggi, and less commonly: sleepy lizard. The Noongar Aboriginal people refer to T. rugosa as yoorn in their language. T. rugosa has a short, wide, stumpy tail that resembles its head and may serve the purpose of confusing predators.
