Koalas are arboreal marsupial herbivores native only to Australia; this means they live in trees (arboreal), like Kangaroos they have pouches in which they carry their young (marsupial), and that they only eat plants (herbivore). They have a bear-like appearance but are actually not related to bears at all; it is a common mistake to call them "Koala Bears". Their closest (but still very distant) relatives are wombats, who are also marsupials, but are burrowing animals. Koalas can be found mostly on the east coast of Australia, from tropical north Queensland all the way south to Victoria, and even as far west as Adelaide. Koalas survive almost solely on eucalypt leaves (which is why they live in eucalyptus trees) from which they obtain 90% of their hydration. In fact, this is where the name "Koala" comes from; it literally means "no drink" in Australian Aboriginal language.
