There are 4 sub-species that commonly referred to as kangaroo,
The red kangaroo is the largest of all kangaroos, the largest mammal native to Australia, and the largest surviving marsupial. It is found across mainland Australia, avoiding only the more fertile areas in the south, the east coast, and the northern rainforests. This species is a very large kangaroo with long, pointed ears and a squared-off muzzle. It has two forelimbs with small claws, two muscular hind-limbs, which are used for jumping, and a strong tail which is often used to create a tripod when standing upright.
|Eastern Grey Kangaroo|
The eastern grey kangaroo (Macropus giganteus) is a marsupial found in southern and eastern Australia, with a population of several million. It is also known as the great grey kangaroo and the Forester kangaroo. Although a big eastern grey male typically masses around 66 kg. and stands almost 2 m tall, the scientific name, Macropus giganteus (gigantic large-foot), is misleading, as the red kangaroo of the semi-arid inland is, at 85 kg, larger.
|Western Grey Kangaroo|
The western grey kangaroo is one of the largest kangaroos in Australia. It weighs 28–54 kg and its length is 0.84 – 1.1 m with a 80–100 cm tail, standing approximately 1.3m tall. It exhibits sexual dimorphism with the male up to twice the size of female. It has thick, coarse fur with colour ranging from pale grey to brown; its throat, chest and belly have a paler colour. It feeds at night, mainly on grasses but also on leafy shrubs and low trees. It has a nickname stinker because mature males have a distinctive curry-like odour.
