Common brushtail possum

The common brushtail possum is a nocturnal, semi-arboreal marsupial of the family Phalangeridae, it is native to Australia, and the second largest of the possums. Trichosurus vulpecula has large eyes and tall rounded ears. Its fur is short but dense, and its tail is typically long and is covered in long bushy fur. In some subspecies, the fur on the tail is the same length as on the rest of the body. Throughout its range, there is considerable variation in the coat color of Trichosurus vulpecula. Color seems to vary according to habitat, and several subspecies have been identified. Three of the subspecies are typically grey in color: T.v. vulpecula is found throughout southern Australia; T.v. arnhemensis is found in the northern tropical regions of Australia; and T.v. eburacensis is found in Cape York. T.v. johnsoni is found in eastern Queensland, and is typically red in color. The subspecies T.v. fuliginosus, which is found in Tasmania, has black coat coloration. In all subspecies, the underside is lighter in color. A scent gland located on the chest is used to mark territories. The reddish secretions from this gland give the fur around it a brown or reddish appearance. Like most marsupials, the females have a small, forward opening pouch that is used in reproduction.
