✦ Synopsis


Previous work (Loeb, 1972) showed that strobilation could be induced in Chrysaora quinquecirrha (Desor) by subjecting polyps ~o a period of chilling followed by wanning. It is shown here, that the onset of strobilation and the rate at which this process occurs in a population of C. quinquecirrha polyps is positively related to the amount of light received during chilling and in the period following warming. The absence of light during either period delays the onset of strobilation. The intensity of coloration of C. quinquecirrha polyps before strobilation appears to be correlated with the amount of light to which they have been exposed during chilling.
