Common Brushtail Possum

The common brushtail possum (Trichosurus vulpecula, from the Greek for "furry tailed" and the Latin for "little fox", previously in the genus Phalangista) is a nocturnal, semi-arboreal marsupial of the family Phalangeridae, it is native to Australia, and the largest of the possums.

Like most possums, the common brushtail possum is nocturnal. It is mainly a folivore, but has been known to eat small mammals such as rats. In most Australian habitats, leaves of eucalyptus are a significant part of the diet but rarely the sole item eaten. The tail is prehensile and naked on its lower underside. There are four colour variations: silver-grey, brown, black and gold.

It is the Australian marsupial most often seen by city-dwellers, as it is one of few that thrive in cities, as well as a wide range of natural and human-modified environments. Around human habitations, Common Brushtails are inventive and determined foragers with a liking for fruit trees, vegetable gardens, and kitchen raids.

In New Zealand, where it was introduced in the 19th century, it is a major agricultural and conservation pest.
