Koalas are considered as one of the most popular animals in Australia. People are aware of them and they regard Koalas as one of the cutest animal as well. Koalas are also harmless and peaceful animals of Australia. When koalas are born, they are usually less than an inch long and weigh less than a gram. They emerge from the birth canal directly into the mother’s pouch where they nurse and grow. The joeys don’t even peek out of the pouch for six or seven months, and they cling to their mothers until they reach a year in age, at which point they leave to find their own territory.
