|Tiliqua rugosa rugosa| 4, see text 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. Etymology and taxonomy
