The koala is native to Australia, and is a fairly small marsupial. The koala gets it's name from an old Aboriginal word meaning "no drink", because it gets over 90% of it's hydration and fluids from the leaves they eat. A koala drinks only when they're sick, there's not enough moisture on the leaves, or if there's a drought, etc.
Koalas are like humans, and need to have company or be near other koalas, so they all find forests where it is suitable for a fairly big population of koalas to live. Koalas today are found all over Australia.
In Australia, there are over 600 types of eucalyptus, but koalas only eat around 40-50 varieties. Different species of eucalypt grow in different parts of Australia, so koalas in Queensland would have a very different diet compared to koalas in Victoria.
Sometimes koalas will eat from wattle or tea trees, if gum leaves are all dried out. Eucalyptus leaves are very fibrous and low in nutrition, and koalas sleep up to 18 hours a day. Each koala eats around 200-500 grams of leaves everyday.
The koala has a great sense of balance, and it's body is lean and muscular, and quite long. It's arms and legs are basically the same in length, and the koalas climbing strength comes from the thigh muscle joining the shin.
The koalas paws are especially made for gripping and climbing, with rough pads on the palms souls, helping it go grip onto tree trunks and branches. They have long sharp claws to help them climb.
Koalas have thick woolly fur that protects them from high and low temperatures. It also acts like a raincoat when it rains, protecting the fur from too much moisture. Their fur is is normally grey, or brown with a little white and sometimes black.
Koalas use different sounds to communicate with each other. Males make a deep grunting bellow to let others know his position. Females know only really make noises if they have a baby to communicate with them, so they make soft clicking squeaking sound and gentle humming noises to one another as well as gentle grunts to the baby, showing annoyance.
