The grey kangaroo, sometimes known as the great grey, is one of the best-known of all kangaroo species, along with the similar-sized red kangaroo. Its closest relative is the western grey kangaroo (Macropus fuliginosus). In total there are 55 species of kangaroo, wallaby & wallaroo belonging to the family Macropodidae (from a Greek word meaning 'big feet'). They are all similar animals but differ in size & build, from the large red and grey kangaroos to the rabbit-sized rat kangaroos. In general, a wallaby is simply a small species of kangaroo, having hind-feet measuring less than 25cm.
