Red kangaroos (Macropus rufus) are large animals with extremely long and powerful hind legs and feet.
Their tail is also long and muscular but their front limbs are short.
When moving fast they hop on their hind legs, using their tail as a counterbalance, and when moving slowly they use their tail as an extra limb, taking their weight on their front limbs and tail while hopping their hind feet forwards.
Their fur is soft and reddish brown (greyer in females). They have quite long muzzles and rather large ears, making their heads look a bit like those of deer.
Length: up to 1.4m
Tail length: 1m
Weight: up to 85kg
The Red Kangaroo is mainly active in the cool of the evening or night, and lives alone or in small groups called 'mobs' (although food shortages can cause them to congregate into larger groups).
Membership of these groups is very flexible, and males (boomers) are not territorial, fighting only after females (flyers) which come into heat.
The largest males are dominant, and control most of the matings.
