There is only one main species of koala (Phascolarctus Cinereus), and some disagreement about whether there are two or three sub-species, or indeed, whether there are any sub-species at all.
According to the Australian Koala Foundation (see link below) the generally accepted sub-species are:
3
100,000 Koalas
Koalas, like many mammals, bathe by licking themselves.

Koalas do not have a home in the sense of a single, central location. Their "homes" are always in eucalyptus trees. They do not use tree hollows, nor do they make nests. Koalas nestle in the forks between trunk and branches, and shelter within the branches and leaves. This gives them adequate protection from all kinds of weather. Koalas do have a range of home trees, however - trees that are part of each koala's specific territory.
Adult koalas are simply called koalas.
