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

Distribution and habitat
They inhabit the tropical rainforests of New Guinea and far northeastern Queensland, and some of the islands in the region — in particular the Schouten Islands and the Raja Ampat Islands near the northwestern coast of New Guinea. Although most are found in mountainous areas, several species also occur in lowlands, such as the aptly named lowlands tree-kangaroo. Most tree-kangaroos are considered threatened due to hunting and habitat destruction. Because most of their motion and living involves climbing and jumping from tree to tree, they developed better locomotion. Tree kangaroos thrive in tree tops as opposed to their cousin the kangaroo which survives on mainland in Australia. Two species of kangaroo are found in Australia, Bennett's (Dendrolagus bennetianus) which is found north of the Daintree River and Lumholtz's (Dendrolagus lumholtzi). Tree kangaroos have adapted better to regions of high altitudes. Tree kangaroos have at least fifteen known subspecies living in Papua New Guinea and Australia. Tree kangaroos must find places comfortable and well adapted for breeding as they only give birth to one joey per year. They are known to have one of the most relaxed and leisurely birthing seasons. They breed cautiously in treetops during monsoon season. Their habitats are breeding grounds for danger as they can easily fall prey to their natural predator, amethystine pythons, which also climbs and lives amongst the treetops in the forests. Tree kangaroos are known to be able to live in both mountainous regions and low-land locations.
