Read the passage and answer the question.

Most people refer to koalas as koala bears, but they are not bears at all. They are actually marsupials and are in the same family as the kangaroo. Koalas live in eucalyptus forests in eastern and southeastern Australia. Adult koalas are one of only three mammals that can survive on a diet of eucalyptus leaves. These leaves contain 50% water, requiring them to seldom drink water since they obtain it through the leaves.

Since the koala is a marsupial, the baby crawls into the mother’s pouch as soon as it is born. Baby koalas are called “joeys.” When they are born, they are blind, hairless, and less than one inch long. Joeys remain in their mother’s pouch for the next six months, after this, they ride on their mothers’ backs until they are almost one year old. At that time the joey is able to live independently.

According to the passage, which statement is true about new-born koalas?
