Abstract: The sea anemones Anthopleura elegantissma, Metridium senile, and Corynactis californica are observed to engage in interspecific aggression. This aggressive behavior is elicited only thru tentacle contact. The receptors that detect interspecific antagonists are located only on the tentacle tips in Anthopleura and Metridium, while Corynactis detects from the sides of its tentacles. Each species of anemone exhibits an aggressive behavioral pattern peculiar to its own species.
