The diet of a koala consists largely of eucalyptus leaves. Koalas consume over two pounds of these leaves in a day. These mammals have an extended stomach that works to keep them safe from the poison in eucalyptus leaves.
Koalas are found in the eastern part of Australia, an area that is abundant in eucalyptus trees. Koalas spend a large part of the day sleeping, being known to sleep for as many as 18 hours. These mammals consume most of their food during the nighttime. Koalas can live for up to 20 years in the wild. The average height of a koala is between approximately 23 and 34 inches, and the average weight is roughly 20 pounds.
