Gray kangaroos are slightly smaller, and the wallaroo is smaller still. Those are the three main types of kangaroo, but technically wallabies and pademelons are part of the kangaroo family, and there are several different types of them.
The kangaroo is a marsupial from the family Macropodidae (macropods, meaning large foot). In common use the term is used to describe the largest species from this family, especially those of the genus Macropus : the red kangaroo , antilopine kangaroo , eastern grey kangaroo , and western grey kangaroo . Kangaroos are endemic to Australia . The Australian government estimates that 34.3 million kangaroos lived within the commercial harvest areas of Australia in 2011, up from 25.1 million one year earlier. As with the terms  wallaroo  and  wallaby , kangaroo refers to a polyphyletic grouping of species.
