A kangaroo is a large marsupial native to Australia. Known for its powerful hind legs, a kangaroo can hop at high speeds and cover great distances. They have a strong tail that helps them balance while moving and can also be used for support when sitting. Kangaroos are herbivores, primarily feeding on grass and leaves. Kangaroos are social animals and often live in groups called mobs. They have a unique reproductive system, where females carry their young, called joeys, in a pouch until they are mature enough to explore the outside world. This adaptation helps ensure the survival of their young in the wild.
