Inhibition of nematocyst discharge correlated with feeding in a sea anemone, calliactis tricolor (leseur)

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. Access through your institution Buy or subscribe This is a preview of
