Reproduction

The koala usually mates on February to November. So they can mating anytime except for December and January. Because it's too cold. After mating, the koala pregnancy lasts about 30 days.  When the young koala is ready to be born, the female sits on a branch. It is born without hair. Koalas are marsupials(=Any Australian animal that carries its young in a pocket of skin on the mother's stomach). The still developing koala must make a journey to it's mother's pouch after it's born.  To do so, it has strong arms that grasp it's mother's fur as it makes it's way to the safety of her pouch. The baby koala is called a Joey.  The Joey then attaches its mouth to it's mother's breast and get food from her.  The baby remains in the pouch for about 5 months.  The pouch is important in keeping the baby koala safe. After the 5 months in the pouch, the koala will get out of the pouch. It only goes back into the pouch if it feels unsafe or for sleeping. When the koala is 8 months old, it doesn't goes to the pouch anymore.[2]

Koala eat only eucalyptus leaves. In Australia, eucalyptus trees are 80% of all trees on Australia. Eucalyptus leaves has Alcohol inside. So Koala sleeps 20 hours each day. And eucalyptus has Alcohol so they don't drink water. Sometimes they drink water. They sit down the tree and then, they take a sleep. Because it's safe when they are sleeping. Most Koalas are sleep at daytime and they get started move at night. when koalas get up, they eat first. Sometimes koalas are eat sand, because they remove the poisons which is from eucalyptus leaves through eat sand. Koala does cry. In spring Koala cry very noisy.[3]
