It has long dense brown fur with black ears and a pale brown or cream nonprehensile tail. It has large and powerful claws and a stocky build that gives it a bear-like appearance.
It is mostly solitary and nocturnal.
Its diet consists of various leaves, buds, flowers and fruits. The gestation period is about 30 days, after which, the single young remains in the mother's pouch for up to 10 months.
