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.
