Abstract
IN spite of much work1 neither the mechanism nor the nature of control of the discharge of nematocysts is well understood. These stinging capsules, characteristic of coelenterates, have generally been assumed to be independent effectors2,3, their discharge depending solely on external stimuli, with the animal exerting no control. Some coelenterates, however, seem to be able to modify nematocyst discharge4–8, and we feel that nematocysts should therefore not be considered true independent effectors. Working with the Florida sea anemone, Calliactis tricolor, we have observed a sharp decrease in the number of nematocysts discharged with increased feeding.
