How many legs does a koala have?

A koala has 18 claws.

Although koalas have five digits on each of its four paws, they do not have five claws on each foot or hand. Each hand, or front foot, has five claws. However, there is no claw on the big toe of the hind foot. The second and third toes are fused together, but retain both claws, meaning that they have four claws on each hind foot.
