Each day an adult Australian koala bear eats about 2.5 pounds of eucalyptus leaves, and a baby koala eats about 1.5 pounds. Koala bears are very picky eaters; mostly they only eat eucalyptus trees and not much else. Koalas eat the moist, tender tips of eucalyptus leaves. A meal gives a koala all of the food and water that it needs. Koalas can be as tall as 33 inches and weight as much as 20 pounds.
