Desert Mouse

About the Desert Mouse

The desert mouse (Pseudomys desertor), also known as the brown desert mouse, is a species of rodent in the family Muridae. It is endemic to Australia. The first desert mouse specimen was collected by Australian zoologist Gerard Krefft on the Blandowski Expedition in 1856-57, between Gol Gol Creek and the Darling River.

The desert mouse has bright chestnut brown fur above, interspersed with long dark guard hairs which give it a spiny appearance. Its belly fur is a light grey-brown. The tail looks scaly and slightly bi-coloured, with length equal to or shorter than the animal's head-body length. A defining feature of the desert mouse is its pale orange eye-ring, which may be used to distinguish it from the Western chestnut mouse Pseudomys nanus where their habitat overlaps in the northern Tanami Desert.

Typical measurements for the desert mouse are 70–105 mm for head-body length, and 67–103 mm for tail length. Weight is between 15-35 g. Widespread throughout the arid zone of Australia, the desert mouse also inhabits in the north dry savannah region of Queensland. Its preferred habitat ranges from sand dunes with spinifex to rocky hillsides... Wikipedia →
