A koala bear has a short chubby body covered with gray fur, a round head, large hairy ears, a large nose and small dark eyes. Although they resemble teddy bears, they are actually not "bears" at all but marsupials.
In the wild, koala bears are exclusively found in eastern and southeastern Australia. In addition to their other physical characteristics, they have sharp claws and opposable fingers that help them climb trees. Their diet consists of eucalyptus leaves.
As with all marsupials, koala bears have a marsupial pouch where the cub lives for about six months. After leaving the pouch, the cub rides on the mother's back for another six months. Koalas spend most of their lives in trees, rarely going on the ground.
