Koala paws (Phascolarctos cinereus). The koala has five fingers per paw to assist climbing. It is one of the few mammals that has fingerprints similar to human fingerprints. The koala is an arboreal (tree-living) marsupial and feeds mainly on the leaves from a few species of eucalyptus trees. It inhabits the forests of Tasmania and eastern Australia, living alone or in small groups. Photographed in Australia.
