The brown-eared woolly opossum is an arboreal marsupial with a dense coat and a long, grasping tail. It lives in South American forests.
It has a broad head, pointed snout, and long, dense fur. The back and sides range from reddish brown to pale brown, while the underside may be yellowish white or gray. Its prehensile tail is furred mainly near the base.
It is solitary, nocturnal, and arboreal, resting in hollow trees by day. Fruit makes up most of its diet, with invertebrates and small vertebrates also recorded.
