In my garden..... also known as shingle back or stumpy tail...

Stump-tailed skink (Tiliqua rugosa) is a large lizard (30-35 cm) found in Australia. It has a heavily armored body and can be found in various colors ranging from dark brown to cream. The skink, also known as the shingleback, bobtail, pine-cone lizard, bog-eye or sleepy lizard has a short, stumpy tail, and moves rather slowly. Male and female shinglebacks stay together for about eight weeks during the breeding season, then separate. They sometimes reunite the following year. The female produces live young, one or two at a time. The young emerge and eat their afterbirth immediately.
