A kangaroo is any of several large animals of the Macropodidae, a marsupial family that also includes the wallabies, tree-kangaroos, wallaroos, pademelons and the Quokka, some 63 living species in all. Kangaroos are endemic to the continent of Australia, while tree-kangaroos are found on both Australia and New Guinea.
The term kangaroo is sometimes used in a broader sense to refer to all members of the macropod family, but is generally reserved for the four largest macropods, namely the Red Kangaroo, the Antilopine Kangaroo, and the Eastern and Western Grey Kangaroo of the Macropus genus. Smaller macropods are called wallabies, while some intermediate in size are called wallaroos.
