This photo was taken... in Australia ! There are four species that are commonly referred to as Kangaroos:
1 The Red Kangaroo (Macropus rufus) is the largest surviving marsupial anywhere in the world. Fewer in numbers, the Red Kangaroo occupies the arid and semi-arid centre of the continent. A large male can be 2 metres tall and weigh 90 kg.
1 The Eastern Grey Kangaroo (Macropus giganteus) is less well-known than the red (outside of Australia), but the most often seen, as its range covers the fertile eastern part of the continent.
1 The Western Grey Kangaroo (Macropus fuliginosus) is slightly smaller again at about 54 kg for a large male. It is found in the southern part of Western Australia, South Australia near the coast, and the Darling River basin.
1 The Antilopine Kangaroo (Macropus antilopinus) is, essentially, the far-northern equivalent of the Eastern and Western Grey Kangaroos. Like them, it is a creature of the grassy plains and woodlands, and gregarious.
In addition, there are about 50 smaller macropods closely related to the kangaroo in the family Macropodidae (wallabies, tree-kangaroos, pademelons and several others).
