Another tiny marsupial is the Long-nosed Potoroo. This species reaches only 1.3 kg in weight! They range in colour from red-brown on the west coast to grey on the east coast, with paler fur on the belly. Most individuals have a white tip at the end of their tail. Long-nosed Potoroos are found in Tasmania and on Flinders Island and Bruny Island. The potoroo can still be found on the east coast of the mainland, but its range has decreased. Their preferred habitat ranges from moderately dry grassy woodland to wet dense scrub. The Potoroo forms a system of tracks or 'runways' under the scrub to move around undetected by predators. Potoroos are nocturnal, spending the hours of daylight in thick vegetation.
Like the Bettong, Potoroos eat seeds, roots, bulbs and insects. However, their favourite treats are underground fungi which they dig up using their strong forepaws. Occasionally, potoroos will venture into gardens and dig up seedlings in a search for worms, insects and fungi. Masked owls, eastern quolls, feral cats and dogs regularly prey on potoroos. The Potoroo has the longest gestation period of any macropod, despite its relatively small size. Gestation is 38 days, followed by another 4 months in the pouch.
