Other names for shingleback lizards (Tiliqua rugosa) include sleepy lizard, bobtail, pinecone lizard, boggi, double-headed lizard, and stumbly lizard. The Shingleback’s skin is exceedingly rough and bumpy, as its name implies.
The colour and pattern of their scales varies with the region, but they are commonly brown to red-brown, with white, yellow or cream markings. Their tongue is dark blue, broad and fleshy.
