Kowari.
The kowari, also known as the bushy-tailed marsupial rat is a small carnivorous marsupial native to the dry grasslands and deserts of central Australia.
The kowari is 16.5–18 cm long, with a 13–14 cm tail. Its diet consists mainly of insects and spiders, but probably also small lizards, birds or rodents. It is known as a voracious predator. It lives in underground burrows.
It is coloured ashy-grey, and its distinguishing feature is the brush of black hairs on the end of its tail. Found in stony desert areas of the Lake Eyre drainage basin, in north-eastern South Australia and southwestern Queensland.
