Each koala eats about 25 pounds of eucalyptus tree leaves per day.
Koalas are marsupials; newborn koalas—called joeys—continue to develop in their mothers' pouches.
Koalas have thick woolly fur that protects them from both heat and cold. It also acts like a raincoat.
More than four-fifths of original koala habitat has been destroyed. People are trying to save what is left.
A female koala is pregnant for only 35 days before giving birth; most of the joey's growth and development takes place in the mother's pouch.
Koalas spend as many as 18 hours a day napping and resting.
Koalas smell like cough drops because of their diet of eucalyptus leaves.
