It is still a commonly held misconception (outside their native Australia) that Koalas are bears due to their similarity in appearance. However koalas are in fact marsupials - animals whom carry their young in a pouch. Koalas are found exclusively in eastern and southern Australia.
The koala is a herbivore, meaning that it eats only vegitation, and it's diet consists almost entirely of eucalyptus leaves. Interestingly, koalas are one of very few mammals (other than primates) that have 'human-like' fingerprints.
