The ursine tree-kangaroo (Dendrolagus ursinus) is a long-tailed, furry, bear-like mammal found only in tropical forests on the island of New Guinea (in Indonesia).

Compared to terrestrial kangaroos, the limbs are short, with broad feet, well-roughened soles and curled claws for climbing.

[2] The ursine tree-kangaroo is nocturnal, solitary and lives mainly in trees, though it can descend to the ground where its gait is bipedal, hopping rather clumsily on its hind legs.

Being a marsupial, a tiny neonate is born about thirty days after conception, and wriggles through the fur of the mother's abdomen to the pouch.

The two main threats it faces are habitat destruction as forests are cleared to provide farming land, and hunting by indigenous peoples for food.
