Their heavy coat helps protect them from both hot and cold weather as well as helping to keep them dry in the rain. Koalas in the southern areas of Australia have adapted to the colder temperatures with thicker, heavier fur and they are larger than koalas from warmer regions.
Koalas stay in their eucalyptus trees. Their thick fur is partially waterproof, although it does not protect them in a particularly heavy downpour.
Winters are relatively mild in Australia. Koalas have thick fur so they don't need anything to prepare for colder weather.
They have fur.
The koala's fur acts like an insulator and a raincoat, keeping them warm in winter, cooler in summer and stopping the rain from saturating the animal.
Koalas have thick fur which serves two main purposes. The fur has two layers. Koalas have a dense undercoat, and on top is longer, coarser fur that grows out through the undercoat. The undercoat keeps the koala warm in winter and cooler in summer, while the outer, fluffy layer protects them from rain.
Koalas live in exactly the same place during winter as they do in summer, and that is in eucalyptus trees. Despite the changing seasons, koalas do not need to change where they live, as they are well equipped physically for cold winter nights and hot summer days.
Koalas are mammals, and most mammals have skin, either with or without fur or hair. In the case of the koala, the fur has particular functions. The koala's fur helps to keep it cool in summer and warm in winter. Its outer layer is partially waterproof, so that when rains do come, the koala does not become saturated.
A koalas skin is covered with fur. Koalas have a woolly light to dark grey fur with brown and white patches and a cream belly.
Koalas have woolly light to dark grey fur with brown and white patches and a cream belly. Southern koalas are darker in colour than their northern counterparts and have longer fur.
Not any more. Koalas were once killed for their fur, as koalas fur was in high demand overseas. Koalas are now protected by law, and it is illegal to hunt them for any reason.
Koalas in the north have woolly light grey fur. The difference between the northern koalas and those found in the south is that southern koalas have darker grey fur tinged with brown.
