What do koala's ears look like?

When a koala is first born, it resembles a kidney bean. Less than 2cm long, it is hairless, earless and blind.

Most of a joey's (baby koala's) development takes place in the mother's pouch. As it grows, it begins to actually look like a koala. By the time the young koala is old enough to crawl out of its mother's pouch, it is a miniature replica of its parents.
