Stichodactyla is a genus of sea anemones, of the family Stichodactylidae. They are host anemones, which maintain a relationship mutualistic with other animals, in their case with crabs of the genus Mithraculus, shrimp of the genus Periclimenes , and with various species of clownfish, of the genus Amphiprion, establishing a relationship of coexistence. In this way, crabs and fish protect themselves from their predators between the stinging tentacles of the anemone, and the anemone benefits from the cleaning of its oral disc and tentacles as a result of the continuous movements of the animals.
