This species is a very large kangaroo with short, red-brown fur, fading to pale buff below and on the limbs. It has long, pointed earlobes and a squared-off muzzle. Females are smaller than males and are blue-gray with a brown tinge, pale gray below, although arid zone females are colored more like males. It has two appendages with small claws (much like arms); two muscular legs, which are used for jumping; and a tail, which is often used like a third leg for balance.
Red kangaroo\\\\\\\'s legs work much like a rubber band. The male Red kangaroo can leap in full force approximately 9.14 m in one leap.
Males grow up to 6 feet tall and weigh up to 187 lbs . Females grow up to 3.6 ft tall and weigh up to 77 lbs . Tails can be up to 3 ft long.
The Red kangaroo is mainly active in the cool of the evening or night, and lives alone or in small groups called mobs. Membership of these groups is very flexible, and males (boomers) are not territorial, fighting only after females (flyers) come into heat. The largest males are dominant and control most of the matings.
