Physical Description Of Kangaroo.


Kangaroos are not greatly bothered by predators, but when pursued by dogs, for instance, often head for water, standing submerged to the chest, and attempting to drown the attacker by holding him underwater. Another defensive tactic is to get their back to a tree and kick at their adversary with their clawed hind feet, sometimes with sufficient force to kill a man.
Kangaroos have large, powerful hind legs, large feet adapted for leaping, a long muscular tail for balance, and a small head. Like all marsupials, kangaroos have a pouch called a marsupium in which their young complete their development after birth.
Kangaroos are the only large animals to use hopping as a means of locomotion. The comfortable hopping speed for Red Kangaroos is about 20–25 km/h (13–16 mph), but they can hop as fast as 70 km/h (43 mph) over short distances. This fast and energy-efficient method of travel has evolved less in response to the danger of predators, but more because of the need to regularly cover large distances in search of food and water.
