Kangaroo is any kind of marsupial belonging to the order Kangaroo, mainly distributed in mainland Australia and parts of Papua New Guinea. Some of them are unique to Australia. Different types of kangaroos live in a variety of natural environments in Australia, from cool rain forests and desert plains to tropical areas. Kangaroos are the mammals that jump the highest and farthest. "Kangaroo" sometimes refers to all marsupials. The word was derived from Guugu Yimidhirr, an Australian Aboriginal language, and the word kangaroo was later named by Joseph Banks on James Cook's first sailing trip.
