Koala
Koala, an Australian marsupial (animal that suckles its young in a pouch). The koala lives in trees and feeds almost entirely on eucalyptus leaves. Its sturdy, tailless body is about 24 inches (60 cm) long. The koala has large, rounded, shaggy ears. Its fur is mostly ashy gray. The koala has strong claws which it uses for climbing. The large toe of each foot and the first two fingers of each forepaw are opposable. Since the early 1900's, the number of koalas has greatly decreased, mainly because of loss of habitat.
