Exposure of the acontium to an illumination of 40klx in 6×10^<-4>M eosin solution in sea water was sufficient to cause the nematocyst explosion, while the sensitization weaker than that tends to result in capsule extrusion without explosion. Nematocysts in isolation were found insusceptible to photodynamic activation. The results were understandable along the line of the chloride ion hypothesis of nematocyst response, though some additional explanation seemed necessary as to the effect found of Cl-poor media which facilitate the explosion response to a photodynamic stimulus.}, pages = {83--91}, title = {The Physiological Mechanism of Nematocyst Responses in Sea Anemone : VIII.
