The koala is small and cute. It spends most of its lifecycle (生命周期) in the trees. It eats, sleeps and nurses (养育) its baby there, and it only comes down to the ground if necessary. The koala is loved by many people for its small size and cartoon-like feature.
A mother gives birth and raises only one baby koala at a time. During the mother’s lifecycle, she will produce up to six baby koalas. A newborn baby koala does not look like an adult because it is born blind with undeveloped features.
After the baby koala is born, it makes its way to the mother’s pouch (育儿袋) and lives inside. Then it develops its eyes, legs and fur. In fact it lives in the mother’s pouch for about six months.
At last the baby koala gets out of its mother’s pouch, and the mother carries her baby on her back. Some baby koalas want to use the safety of the pouch longer than necessary, but their size is too big for them to climb back inside. When the next baby koala is born, it is time for last season’s baby to say goodbye.
