Sea animals, like sharks and eels, can get food stuck in their teeth like you do. However, a shark can’t use a toothpick or floss. Many sea animals are also bothered by tiny bugs, or parasites. In the waters of Hawaii, a special fish helps other sea animals with these troubles. This small fish is called the Hawaiian cleaner wrasse. The brightly striped cleaner wrasse picks off parasites and eats them. It also eats the leftover food in sharks’ teeth. Sharks don’t eat the wrasse because they need its cleaning services.
