Kangaroos are the multicellular animals and they are complex one because they are mammals. As we all know they are the only large animals to use hopping as a means of locomotion and they also hop really fast. The comfortable hopping speed for red kangaroo is about 20–25 km/h (13–16 mph), but speeds of up to 70 km/h (44 mph) can be attained, over short distances, while it can sustain a speed of 40 km/h (25 mph) for nearly. They are also adept swimmers ,and often flee into waterways if threatened by a predator. From the picture we can see kangaroos have large, powerful hind legs, large feet adapted for leaping, a long muscular tail for balance, and a small head.

A large male can be 2 meters (6 ft 7 in) tall and weigh 90 kg (200 lb). The second one is eastern grey kangaroo which is the most common one .The last two kinds of kangaroos are The western grey kangaroo and The antilopine kangaroo. For eating kangaroos are autotroph and they have chambered stomachs similar to those of cattle and sheep They regurgitate the vegetation they have eaten, chew it as cud , and then swallow it again for final digestion.
