Swimming sea anemones of Puget Sound: swimming of Actinostola new species in response to Stomphia coccinea.
Swimming as a response of the sea anemone Actinostola new species can be elicited as a result of contact with the submarginal surface of another swimming sea anemone Stomphia coccinea. However, Stomphia does not swim as a result of contact with Actinostola. In all other known respects, swimming is caused in both species by the same stimuli, including certain starfishes, a nudibranch, and electrical stimuli. No agent that causes Actinostola to swim has been detected in extracts, rubbings, or dried matter from Stomphia.
