The boodie (Bettongia lesueur), also known as the burrowing bettong, 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. This animal, first collected during an 1817 French expedition of the west coast, was named after Charles Lesueur, an artist and naturalist who accompanied a previous French expedition. B. lesueur is known by many common names, including the tungoo, Lesueur’s rat-kangaroo, and the short-nosed rat-kangaroo.
