The Potoroinae are distributed in Australia and Tasmania. They inhabit steppes, thickets, and forests, living in burrows, crevices, and grassy nests. They are nocturnal animals. Most are herbivorous; some are omnivorous. The Potoroinae reproduce several times a year, each time bearing one young, which the mother carries in her pouch for about four months. Many species are few in number. Some Potoroinae damage orchards and vegetable gardens.
