The koala is one of the few mammals that has a fingerprint similar to a human fingerprint. Two toes on the back paws are joined together which forms a “grooming tool” which the koala uses to comb their fur and get rid of ticks. They have five digits on each paw, the front paws have two opposable thumbs and three fingers. Koalas have large sharp claws which help them in climbing trees. They have a small tail that is mostly hidden by their fur. They have a round head with a large black nose. They have soft wool-like grey fur with patches of white on their stomach, chest and chin and a fringe of white around their ears. The koalas shape is similar to the wombat which is its closest living relative, but the koala has longer limbs. Read on to learn more about these magnificent mammals. They are threatened across their range with significant declines in their population being driven by habitat loss and fires. Here it develops till it is large enough to sit on their back. These animals are marsupials and as a result they will give birth to a live young which is initially raised in a pouch located on their stomach. These animals have adapted to feed exclusively on eucalyptus leaves which are filled with toxins that the koala must work hard to digest.Īs a result of the work needed to digest their food they will spend much of their time resting and may spend up to 20 hours each day sleeping.

A firefighter helplessly watching a bushfire rage through the forest in Queensland, Australia. Throughout the years millions of hectares of habitat (up to 10 million hectares) have been lost and most losses occurred in Queensland and New South Wales regions. Almost 2 million hectares of koala habitat were cleared in Queensland to make way for urbanization and developments. The biggest habitat loss recorded happened in the 1990s. Habitat loss is the biggest threat koalas are facing today. And their habitat is getting even smaller today due mainly to the clearing of eucalypt forests. Their habitat shrunk due to the change in climate in those areas. Habitat Lossįossil remains of koalas suggest that these creatures covered a larger area throughout Australia. This is why injured koalas that are treated by carers are often taken back to their home range when they are better. Most of the time, koalas that are taken out of their ranges adapt quite poorly to new environments, so many do not survive. They stay in their home range or communities for the rest of their lives and will only move if forced. Koalas stay within their range and are very territorial. Males generally have a bigger home range than females and are more active. This is done to make their territory or home range. The rubbing of the scent gland triggers the release of a fluid that is smelly and distinct. Male koalas use this gland to attract mates, they also rub this against the trees. It is located in the middle of the chest. This area is the male koala's scent gland that is often dark, moist, and hairless. Marking TerritoryĪ mature male koala can be distinguished from the rest because of a special area on the chest. The trees are their bedrooms, bathrooms, and backyards. They don’t make holes, nests, or dens, and instead, sleep right on the branches. They live high up on the trees away from most ground predators. They feast on eucalypt leaves but only eat a few species hence their distribution in different areas of Australia depends on the type of eucalypt trees that are abundant in the area. Unlike other animals, they don’t inhabit just one tree but instead, travel from one tree to another within their home range. ![]()
