Doria's tree kangaroo (Dendrolagus dorianus), the heaviest tree-dwelling marsupial in the world, is, despite appearances, closely related to the well-known kangaroos that can be found on the plains of Australia. Like the ground kangaroos, Doria’s tree kangaroo has a long, well-furred tail, strongly developed hindquarters, and females have a forward-opening pouch in which the newborn infants develop. Its fairly long fur is a shade of brown, with the fur on the neck and back growing in a reverse direction, thought to stop water running over the face of the tree kangaroo as it sits with its head lower than its shoulders. The large feet bear cushion-like pads covered with roughened skin, and some of the nails are curved. This, along with the tail which helps the tree kangaroo balance and brace itself when climbing, makes this species adept at living in the trees. The scientific name of Doria’s tree kangaroo, Dendrolagus (Say it: DENN-DROH-LAGG-uss), is derived from Greek words ‘dendron’, meaning tree, and ‘lagos’ meaning hare.
