| Abstract: | Following tests for initial responsiveness, the suppressive effect of ingestion ofArtemia salina on the contraction response of the sea anemone,Anthopleura elegantissima, was assessed. During testing, repeated presentations of a water-stream stimulus occurred over a period of 70 min. All subjects also underwent control testing in which the water-stream sequence was presented in the absence of priorArtemia ingestion. Significant suppression of oral disk contraction to the water stream was observed followingArtemia ingestion with and without water exchange during testing. The relationship of this finding to similar results obtained withHydra is discussed. |
