What plant is the koala bear partial to?

Answer 1

Koalas are not bears. They are marsupials, unlike bears. Koalas' survival depends on eucalyptus trees, but not on just any eucalyptus tree. While there are hundreds of different eucalyptus species in Australia, koalas feed 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 koalas in the south will be different to those eaten by northern koalas.
