Koalas (Phascolarctos cinereus ) are herbivores feeding on leaves from eucalypt and non-eucalypt tree species.
Interestingly, a majority of the diet of the koalas comes from a few of the eucalyptus tree species with the examples of the following: Eucalyptus viminalis , Eucalyptus punctata , Eucalyptus ovata , Eucalyptus camaldulensis , and Eucalyptus tereticornis .
Eucalyptus leaves are very toxic, especially to animals , but koalas have a specialized mechanism to go around this toxicity. Koalas have bacterial flora in their stomachs, which comes in handy to metabolize the toxins from eucalyptus leaves. There is only 1 Koala species that exists, Phascolarctos cinereus . However, there appear to be differences in the scientific community’s opinions on whether 3 subspecies of Koalas exist or if these subspecies can only be viewed as races. The koala’s fur varies from light grey to brown depending on their location. Koalas living in the south of Australia tend to have a thick and dark coat, which is sometimes browner. Brown koalas are mostly found in South Australia and Victoria. Those living in north Australia spot a light grey hue, mostly found in Queensland. They tend to be smaller compared to their southern counterparts. Koalas living in Australia’s New South Wales state have a grey-brown color. Koalas are arboreal, meaning they will tend to inhabit forested areas, especially those with eucalyptus trees.
They will only come to land when they need to, like looking for a new place to live or searching for water or safety. Aside from this, koalas will spend most of their lives on trees.
