Koalas also love to sleep. They can spend up to 19 hours a day sleeping or resting. Koalas are peaceful animals but can be dangerous if bothered. They have very long, sharp claws that help them hang onto trees. They grip the branches so firmly that it is almost impossible to pull them off.
Koalas spend most of their day up in trees but when they are on the ground they can run fast.
When it gets cold, Koalas will curl or roll up to stay warm. Female Koalas have one baby at a time. The baby Koala is very small, about the size of a bean. The baby stays in its mother's pouch where it nurses for about six months before it starts to come out. At a year old the baby is old enough to be on his own.
