Mountain brushtail possum

The mountain brushtail possum, also called the southern bobuck, Trichosurus cunninghami, is a nocturnal, semi-arboreal marsupial of the family Phalangeridae that is native to southeastern Australia. It was not described as a separate species until 2002, when morphometric differences led to the earlier mountain brushtail possum being split into this southern form and the northern short-eared possum, although genetic divergence may not support the split. Bobucks weigh 2.5 to 4.5 kg, den in tree hollows by day and forage at night, and depend in mountain country mainly on Acacia species, especially silver wattle. They keep the same home range for life, mate in autumn, and may be the longest lived marsupial species.
