Koala sleeping. The koala (Phascolarctos cinereus) is relatively sedentary and sleeps for up to 18 hours a day. This is due to its poor diet, which consists mainly of the leaves from a few species of eucalyptus trees. It is arboreal (living in trees) and inhabits the forests of Tasmania and eastern Australia, living alone or in small groups. Photographed in Sydney, Australia.
