Report Text About Koala

The koalas that live in southeastern Australia are larger than those that live in northeastern Australia. They also have thicker, darker fur. The southeastern koalas range from 9 kg to 14 kg, while the northeastern ones are about 6 kg to 7 kg.
 A koala’s closest living relative is the wombat, another marsupial that lives in Australia. Koalas are believed to have evolved from large koala-like animals that lived in Australia millions of years ago. The oldest koala-like fossils that have been found are about 25 million years old.

One of the things that make koalas so special is that they’re so highlyadapted to their habitat. The only place they live is in sub-tropical andtemperate forests. But not just anyforests—they live only in eucalyptus tree forests. That’s because just about the only thing koalas will eat is eucalyptus leaves. But not justany eucalyptus leaves either! Of the 600 species of eucalyptus trees in Australia, koalas eat the leaves of only about 50 of them. And even out of these, they will have just a few favorites that they eat most of the time. Koalas in different regions eat different kinds of eucalyptus leaves.

Out on a Limb

Imagine having your favorite food at your fingertips anytime you wanted it. That’s what life is like for koalas. They live high in the tops of the eucalyptus trees that they feed on. It sure is convenient. It also keeps them safe from predators, such as wild dogs or even pet dogs. Koalas are well adapted for treetop life. They have a great sense of balance. Plus, they have built-in “climbing tools” like sharp claws and rough paws. Koalas are able to jump from branch to branch or tree to tree. But they’ll also climb backward down to the ground in order to move to a different tree.
