Kangaroos are the largest living marsupials from the family Macropodidae. There are four species commonly referred to as the kangaroo: the red kangaroo, the eastern grey kangaroo, the western grey kangaroo, and the antilopine kangaroo.

Kangaroos are grazing herbivores, which means their diet consists mainly of grasses. They can survive long periods without water.

Kangaroos live and travel in organized groups or "mobs," dominated by the largest male. Male kangaroos are called boomers, bucks or jacks; females are does, flyers, or jills, and the young ones are joeys. The collective noun for kangaroos is a mob, troop or court.
Did You Know?
Kangaroos are the only large animals to use hopping as a means of locomotion.
Because of its long feet, a kangaroo cannot walk normally.
To move at slow speeds, a kangaroo will use its tail to form a tripod with its two forelimbs. It then raises its hind feet forward, in a form of locomotion called "crawl-walking."
Usually, female kangaroos give birth to one joey at a time. Newborns weigh as little as 0.03 ounces at birth - as small as a lima bean! After birth, the joey crawls into its mother's pouch, where it will nurse and continue to grow and develop. Red kangaroo joeys do not leave the pouch for good until they are more than eight months old. Gray kangaroo joeys wait until they are almost a year old.
