Ailurops – Bear cuscuses

This genus consists of two species of arboreal marsupials that inhabit forests in Indonesia and some nearby islands. The two marsupial species of this genus tend to live in pairs or groups of three to four. They are the largest members of the suborder Phalangeriformes (one of three suborders of Diprotodontia).

They are arboreal, slow-moving animals and spend most of the day resting or sleeping, with little time devoted to feeding, grooming, and social interaction. Their primary food source is leaves with very low nutrient levels, and rest periods may be necessary to digest the cellulose. Hunting has dramatically reduced the number of animals in this genus.
