Inhibition of desmoneme and stenotele nematocyst discharge occurs when Hydra attenuata are fed to repletion. Inhibition can be induced by the application of prey homogenates in the external medium. The onset of inhibition is relatively rapid (<30 s) while the release from inhibition is much slower (>20 min). Inhibition is concentration-depedent. Gel chromatography separation of homogenate shows that the inhibitory substance(s) have a molecular weight greater than 5000. These substances cause… CONTINUE READING
