What does the koala eat and how does the koala get its food?

Koalas feed almost exclusively on eucalyptus leaves. They live in eucalyptus trees and eat only a few types of gum leaves from which they get all nutrients and water requirements. They also occasionally eat the gum tree blossoms. Two of the koala's digits on their forelimbs act as opposable thumbs, enabling koalas to reach out and grasp the leaves they want.

While there are hundreds of different eucalyptus species in Australia, koalas eat from only about 60 of the species, consuming about half a kilogram of eucalyptus leaves every day. Koalas will not eat all types of eucalyptus, feeding on just 14 species as their primary food source, specifically, the subgenus Symphyomyrphus. Preferred eucalyptus species vary depending on their locality, so that the species eaten by Victoria koalas will be different to those eaten by north Queensland koalas. Koalas have been known to also eat the buds, flowers and bark of these particular species, while dirt also seems to supplement mineral deficiencies. Koalas have been seen feeding in eucalypt trees such as Manna Gum, Swamp Gum, Blue Gum, Forest Red Gum and Grey Gum
