The boodie (Bettongia lesueur), also known as the burrowing bettong, or Lesueur's rat-kangaroo, is a small marsupial.Its population is an example of the effects of introduced animals on Australian fauna and ecosystems.Once the most common macropodiform mammal on the whole continent, the boodie now only lives on off-lying islands and in a newly introduced population on the mainland at Shark Bay. [15], B. lesueur is very vocal, communicating through grunts, hisses, and squeals. [14], The contraction of the distribution range in Southwest Australia during English settlement has been difficult to determine, Guy C. Shortridge searched unsuccessfully for the species south of Perth in 1909, and Charles M. Hoy obtained a skull that might have been collected at the sub-fossil site at the Margaret River Caves systems located within the Leeuwin-Naturaliste National Park. Test your knowledge of mammals by taking this quiz. MORE READING. Kangaroo rats forage at night and transport food in their cheek pouches to store either in the burrow or in shallow pits nearby.

The fast gait (or bipedal hop) is characteristic of the macropodiforms and uses only the hind limbs, with the forelimbs held close to the body and tail acting as a counterbalance. [5], Once present in all mainland states except Victoria, the burrowing bettong survived as three remnant populations on small offshore islands. Banner-Tailed Kangaroo Rat (D. spectabilis) 4. As pastoral leases spread over the grasslands, livestock grazing reduced vegetation cover, shrinking their habitat. The giant kangaroo rat measures about 13 inches from nose to tail when full grown, and this includes a 7 inch long tail, which has a characteristic tuft of fur on the end, and weighs a little over 5 ounces. As it foraged, it mixed organic matter into the soil, spreading fungi and seeds. Another notable feature of kangaroo rats are their fur-lined cheek pouches, which are used for storing food.
