Kangaroo's are marsupials. They are animals with pouches. Like the koala, who is also a marsupial, they give birth to their baby before it is fully formed. The kangaroo's baby is about a inch long and is completely bald and blind.
Kangaroos have very long and powerful hind legs and feet for hopping and leaping.
Those are the main ways the kangaroo gets around. With these extremely strong back legs the kangaroo can bound up to 40 miles an hour in great leaps. They travel in herds of up to 100 kangaroos and the one who is the most experienced is the one that is usually the leader. Their tail is used as balance. Kangaroo's are found in Australia, Tasmania, and New Guinea.
