The Lumholtz’s tree kangaroo is only one of the 12 species of kangaroo that have taken to the trees. Besides the Lumholtz’s, there is one other in Australia and ten in New Guinea (they keep finding more species). They don’t look so much like the more familiar roos but somewhat like a lemur.

They reside in dense forests and their front feet are well-suited to the trees and give them the ability to climb down a tree backwards. The hind feet are not especially adapted for climbing but their long tails (which grow up to 36.5 inches (93 cm) in length) help them stay balanced. They can use their hind legs to spring from branch to branch and they can even walk on the ground instead of hop (not many species of roos can do this) if they choose. They can be found sleeping together in small groups in the trees.

The tree kangaroo is not an uncommon animal, but they are difficult to spot. They are nocturnal and not much is known about how they mate. They give birth to one offspring at a time. Their favorite foods are grass, leaves and fruits.
