The koala makes its home in eucalyptus forests in eastern Australia. This mammal is about 75 centimeters long. Few animals could survive there, but the koala's body and habits are a good match for it.
One reason the koala survives is sharp claws and rough pads on its paws, which help it grip smooth tree trunks. It also has a very long gut, which helps it break down tough, poisonous eucalyptus leaves.
The koala is a herbivore, which means it is an animal that eats only plants. Its food includes eucalyptus leaves. To find food, it sleeps up to 20 hours a day in the forks of trees.
Young koalas are called joeys. A newborn joey is the size of a jelly bean and grows inside its mother's pouch for about six months. Koalas get most of the water they need from the leaves they eat.
