is closely related to Trichosurus vulpecula, with its most distinguishing feature being its geographic range. It is found in the Northern Territory of Australia, as well as in the extreme northern part of Western Australia. It is also found on Barrow Island (Nowak, 1999).
The Northern Brushtail Possum is able to live in a variety of habitats, including residential areas, forests, and areas without trees that offer caves and burrows for shelter. The most common of these is wooded areas.
The body length is between 35 cm and 55 cm. The tail adds an additional 25 cm to 40 cm. Females weigh between 1500 g to 3500 g and males weigh between 2000 g and 4500 g. The coat is typically grey in color; however, it can also be reddish brown, copper, or chocolate brown. The fur is shorter and less dense than that of the closely related T. vulpecula (Kerle, 1991). The tail is prehensile and covered with fur. The underside is hairless. The tail of theis less hairy and thinner than the tail of T. vulpecula (Kerle, 1991). The ears are long and oval.
Gestation lasts between 17 and 18 days. The pouch period lasts 4 to 5 months. There is generally one offspring per birth. Weaning takes between 6 and 7 months. Individuals reach sexual maturity around age 1 and breed continuously throughout the year. Conception takes place before fully weaning the pouch young. If the pouch young is lost, the female returns to estrus in about 10 days (Nowak, 1999).
The expected lifespan is 11 to 13 years.
is a nocturnal and solitary species. It is arboreal and most commonly nests in tree hollows. This species is an expert climber because of its moist palms and soles, which lead to strong adhesion (Ganslosser, 1990).
Males may occupy a territory of up to 10 acres and females, up to 5 acres (Ganslosser, 1990).has been known to partake in den sharing and to have a certain amount of tolerance for other individuals (Kerle, 1991)
eats a variety of foods. The most common are leaves, buds, flowers, and fruits. It has been documented that, occasionally, birds are eaten (Nowak, 1999).
The Northern Brushtail Possums negatively affect the human populations that they live around in a number of different ways. They often damage flowers, fruit trees, and buildings. They also adversely affect regenerating forests. These animals are also known to carry diseases that are harmful to humans and livestock (Nowak, 1999).
