Living Among Stingers

Clownfish and sea anemones share a famous mutualism, a partnership in which both benefit. Anemone tentacles carry stinging cells that paralyze most fish, but clownfish live among them safely, protected by a special mucus coat. When moving into a new anemone, a clownfish touches it gently at first, a process called acclimation.

Clownfish defend their anemone from fish such as butterflyfish that nibble tentacles. Their waste and food scraps provide nutrients, and their swimming moves water around the host. Clownfish lay eggs on rock beside the anemone, where tentacles help protect them. Only about ten anemone species host clownfish.

In each group, the largest fish is the female, and the next largest is the breeding male. If the female dies, the largest male becomes female, a change called sequential hermaphroditism.
