Red Kangaroo
The Red Kangaroo (Macropus rufus) 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.

Description Red Kangaroo

This species is a very large kangaroo with long, pointed ears and a squared-off muzzle. Males have short, red-brown fur, fading to pale buff below and on the limbs. Females are smaller than males and are blue-grey with a brown tinge, pale grey below, although arid zone females are coloured more like males. 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.

he Red Kangaroo's legs work much like a rubber band. The males can leap over 9 metres (30 ft) in one leap.

Males grow up to a body length of 3 metres (9.8 ft) long and weigh up to 135 kilograms (300 lb). Females reach a body length of up to 1.1 metres (3 ft 7 in) long and weigh up to 35 kilograms (77 lb). Tails can be from 0.9 to 1 metre (3.0–3.3 ft) long. The average Red Kangaroo stands approximately 1.5 metres (4 ft 11 in) tall. Accounts of sizes greater than this are not uncommon, with some large males reportedly reaching approximately 2 metres (6 ft 7 in).

The Red Kangaroo maintains its internal temperature at a point of homeostasis about 36 °C (97 °F) using a variety of physical, physiological, and behavioural adaptations. These include having an insulating layer of fur, being less active and staying in the shade when temperatures are high, panting, sweating, and licking its forelimbs. The Red Kangaroo's range of vision is approximately 300°, due to the position of its eyes.

The Red Kangaroo ranges throughout central Australia. Its range encompasses scrubland, grassland, and desert habitats. It prefers open grassland and prefers areas with scattered trees for shade. The Red Kangaroo prefers to eat grasses. It also includes significant amounts of shrubs in its diet. It can go long periods of time without water, as long as it has access to green plants, since it has the ability to take moisture out of plants.

At times, red kangaroos congregate in large numbers; in areas with much forage, these groups can number as much as 1,500 individuals. Red kangaroos are mostly crepuscular and nocturnal, resting in the shade during the day. However, they sometimes move about during the day. Most of their active period is spent in grazing. Like most kangaroo species, they are mostly sedentary, staying within a relatively well-defined home range. However, great environmental changes can cause them to travel far. The Red Kangaroo is too big to be subject to significant non-human predation. They can use their robust legs and clawed feet to defend themselves from attackers with kicks and blows. However, dingoes and eagles will kill and eat joeys. Joeys are thus protected in their mother's pouch. The Red Kangaroo did have major predators that are now extinct. The Thylacine, considered by palaeontologists to have once been a major natural predator of the kangaroo, is now extinct. Other extinct predators included the Marsupial Lion, Megalania, and the Wonambi.

he Red Kangaroo lives alone or in small groups called 'mobs' (although food shortages can cause them to congregate into larger groups). Each mob is usually made up of 2 to 10 kangaroos, but sometimes a mob can have up to several hundred kangaroos. Membership of these groups is very flexible, and males (boomers) are not territorial, fighting only over females (flyers) that come into heat. The largest males are dominant, and control most of the matings. When male kangaroos fight, they may appear to be "boxing". They usually stand up on their hind limbs and attempt to push their opponent off balance by jabbing him or locking forearms. If the fight escalates, they will begin to kick each other. Using their tail to support their weight, they deliver kicks with their powerful hind legs.

Kangaroos are adept swimmers, and often flee into waterways if threatened by a predator. If pursued into the water, a kangaroo may use its forepaws to hold the predator underwater so as to drown it.
