Fish with 555 Teeth

Did you know, we have two sets of teeth over our lives? We sometimes call the first teeth: 'baby teeth.' 人的一生有兩組牙齒，第一組叫做乳牙。 Kids have 20 baby teeth. As you grow up, you lose your baby teeth and get new 'adult' teeth. 成長過程中，牙齒會慢慢掉光，長出來的新牙齒叫做恆齒。 Do you have all your adult teeth yet? Adults have 32 teeth… well, most of the time. Some animals have many teeth, some have a few, and some have none. But I know about a fish that has 555 teeth! 有一種魚有555顆牙齒！ Yeah! Really! 555!
