Baby Tree Kangaroo Joey, Taronga Zoo, Sydney, New South Wales, Australia

Locomotion
Tree-kangaroos are slow and clumsy on the ground. They move at about walking pace and hop awkwardly, leaning their body far forward to balance the heavy tail. But in trees they are bold and agile. They climb by wrapping the forelimbs around the back of a tree and hopping with the powerful hind legs, allowing the forelimbs to slide. They are expert leapers; 9 metres (30 ft) downward jumps from one tree to another have been recorded, and they have the extraordinary ability to jump to the ground from 18 metres (59 ft) or more without being hurt.
