Three-stripe clownfish

Symbiosis of fish and anemone

Clownfish with three strips live in coral reefs alongside anemones where they take refuge in the event of danger. Unlike other fish which are stung by anemones, clownfish secrete a mucus which prevents them from feeling the anemone’s sting. They bring them food in exchange. All born male, their sex changes when a group forms. The larger specimens become females.
