What is the grizzled tree-kangaroo?
The grizzled tree-kangaroo (Dendrolagus inustus) is a furry, long-tailed mammal native to tropical rainforests on the island of New Guinea (split between Indonesia and Papua New Guinea). Like most tree-kangaroos (genus Dendrolagus), it lives in trees and eats leaves, fruit, and bark. It is a member of the macropod family Macropodidae and carries its young in a pouch like other marsupials. The tree-kangaroo is uncommon and threatened by hunting and habitat loss. It is found in foothill forests of northern and western New Guinea and is indigenous to some of the offshore islands.
