What are some interesting facts about koalas?

Koalas are native to Eastern Australia where their favorite food, leaves from the Eucalyptus tree, are most common. Although koalas are often referred to as "koala bears," they aren't actually bears at all. Rather, they are marsupials, which means "pouched mammal."

Koalas spend the majority of their lives in trees, rarely coming down for any purpose. They sleep for an average of 18 hours a day, eating mostly at night. They get most of their moisture from the leaves in their diet and don't need to drink much water. Because of their exclusive diet of eucalyptus leaves, koalas naturally smell like cough drops.
