Koalas stomach and the small intestine have special cellular contents which help koalas to absorb energy from the chewed leaves. 2.

They live alone on trees and eat on their own. During the winter season, koalas sleep in the hunched sleeping posture which helps them against the severe winter of Australia. Its paws are perfectly designed for moving through trees. Like the human genome, the koala genome contains about 26,000 genes. Koalas have the key ability to regulate their body temperature.

Sometimes, Koalas do not get enough food while other times, they are unable to chew the food rightly. Hippo Digestive System Explained.
