Tiliqua rugosa is a short-tailed, slow moving species of blue-
tongued skink found in Australia.
Three of the four recognized subspecies are found only in
Western Australia, where they are known collectively by the
common name bobtail. The name shingleback is also used,
especially for T. rugosa asper, the only subspecies native to
eastern Australia. T. rugosa has a heavily armoured body
and can be found in various colours, ranging from dark
brown to cream.
It has a short, wide, stumpy tail that resembles its head and
may confuse predators. The tail also contains fat reserves,
which are drawn upon during hibernation in winter.
This skink is an omnivore; it eats snails and plants and
spends much of its time browsing through vegetation for
food. It is often seen sunning on roadsides or other paved
areas.Apart from bobtail and shingleback, a variety of other
common names are used, including stump-tailed skink,
bogeye, pinecone lizard and sleepy lizard.
T. rugosa has a heavily armoured body and can be found in
various colours, ranging from dark brown to cream.Its total
length seldom exceeds 25 inches, but it is a very heavy-bodied
lizard for its length.It has a triangular head and a bright blue
tongue. Its short, stumpy tail is similar in shape to its head.
This possibly evolved as a defence mechanism against
predators, and has led to the common name of "two-headed
skink". Its short tail also contains fat reserves, which the
lizard lives upon during hibernation in winter. Unlike many
skinks, shinglebacks do not exhibit autotomy and cannot
shed their tails
