Koala Taxonomy

Koalas are mostly nocturnal animals. They sleep for 18-22 hours a day. Sometimes they are sleeping in the night and moving around during the day. Other times, they are sleeping during the day and eating at night.It is hard for them to digest euculyptus leaves. That is why they sleep so much. This way they can conservethe little energy that is obtainted from the toxic, low fibered, leaves.

Koalas are on the verge of extinction. There are very few left on this planet. Scientists think that they will be extinct in the next 5-10 years. If we don't do anything about it, they could be gone sooner. There are less than 100,000 koalas left. When Australia was first descovered there were more than 10,000,000. They have no natural predators, although, their one and only enemy is the human kind. People hunt the koalas for their soft, gray fur, and they cut down the trees that serve as the koala's food and living space.

After the joey has spent 6 months in the little pouch devolping, the mother koala will produce a special substance called pap. Pap is a soft, alternate form of fecal matter that consistis of the bacteria nessicary for the baby koala to digest the poisonous eucalyputus leaves. In order for the joey to start eating leaves, it will need the bacteria in it's intestines, therefore, the joey feeds on pap and milk for a few weeks before leaving the pouch.

Each koala’s ‘home' is made up of several trees called "home trees". They visit these same trees regularly. The area covered by these trees is called the Koala’s "home range". Each koala has its own home range, which overlaps those of other koalas but except for breeding purposes, they do normally not visit another koala’s home trees. The size of each home range depends upon a range of factors including the qualityof the habitat and the sex, age and social position in the population of the Koala.

Koala Taxonomy

Koalas are extreemly picky eaters. They eat priamrily eucaluptus leaves, although have been found, ocasionally, to eat eat friut, bark, and/or flower buds. Koalas will only eat the types and leaves that really look the best.

Koalas are eukaryotic orginisims beucase their cells contain nucleus. They are members of the animal kingdom because they are multicellular, heterotrophs, and the species is capable of locomotion. They have backbones, therefore they are classified as chordates. They are in the mammilia category becuase they are mamals and produce milk to feed their young. Becuase of their pouch, koalas are marsupials. They are part of the diprodontia classification becuase of how their teeth are arranged and because of their fused second and third digits, on its back paw. To be classified in the family Phascolarctidae, different characteristics of the animal, including the number and kinds of teeth, and the number of digits on the feet were taken into account. It is also important to note that the koala is the only extant member of its family. Koalas were classified in their genus and species by examining their urinogenital, spermatozoa, karyotype, and serology, along with the aforementioned traits. The name Phascolarctos cinereus literally means ash-colored, leather-pouched bear (Phascolarctos = leather-pouched bear, cinereus ash-colored). The name "koala" comes from the Aboriginal word meaning "no drink" because koalas get most of their water from the eucalypts leaves that they consume.
