What is the difference between a werewolf and a wolf?

A wolf is the ancestor of the dog, and is found mostly in the wild, and is a real animal. A werewolf is a myth, which is a half-man, half-beast (wolf), where the "werewolf" had hair all over the body, the teeth suddenly became sharp and pointy, and the werewolf only transformed during a full moon. A wolf and werewolf only have two things in common: they both have hair all over the body, and they have sharp teeth.
