Koalas are natives of Australia. However, they aren’t found all over the continent. The habitat of koala bears spans (横越) over eastern regions of Australia that include states like Queensland, New South Wales and Victoria and also in the state of South Australia.
Koalas are found where are enough forests of eucalyptus(桉树) trees. The association of koalas and eucalyptus trees is due to the fact that these animals feed on the leaves of eucalyptus trees. But that’s not all. In addition, the trees also serve as the homes of the koalas.
Koalas grow around 27 to 36 inches tall and weigh 5 to 9 kilograms on average. Male kaolas are larger than the females. Life expectancy can stretch up to 17 years.
Like many other animals, the habitat of koala bears is fast decreasing due to deforestation and quick urbanization(都市化). However,efforts by some scientists and animal lovers have successfully introduced these creatures back in certain parts of Australia.
