Tree kangaroos are found only in the rainforests of Australia, West Papua, and Papua New Guinea (PNG). Have some feedback for us? Though often slow moving, even clumsy, in trees, they have evolved other specialisations for their arboreal existence, such as flexible ankle joints and, in some species, the ability to walk bipedally (like humans).This ability to move or rotate the ankle joint is an intriguing feature of their evolution. It is crucial that we understand these animals enough to conserve them. Speak up for species and places through WWF's Action Center.
