The koala(考拉) is possibly one of the best known Australian animals, and is found in four states: Queensland, New South Wales, Victoria and South Australia.
The word “koala” comes from an Australian word meaning “no drink”. Sometimes people call them “koala bears” but koala is not a bear. It belongs to a special group of Australian mammals, called marsupial(有袋类). Female marsupials have a pouch where the baby animals live after they are born.
Koalas have soft, thick, gray or brown fur on their backs. The fur on the stomach is white. The Koala in the south have thicker fur than those in the north because of the cold winters. However, the koalas in the northern part live in warm to hot weather most of the year, so they have thinner fur.A koala has a large nose and round ears. Koalas don’t have tails. Adult koalas weigh between 7kg and 14 kg.
Koalas spend nearly all their time in the trees. They sleep most of the day, but feed and move from tree to tree mainly at night.The reason koala sleep for much of the day is because their food, eucalyptus(桉树) leaves, are so hard that they need a lot of energy(能量;精力)to digest. Sleeping saves energy.
Each koala has a home made up of several trees that they visit regularly. They normally do not visit another koala’s home trees except that a male is looking for a female to mate with.
