Anemones in which there is no significant difference in activity in SS2 are grouped together in the bottom portion of the figure.

This anemone had a 20-min dark period, the only dark period longer than 7 min (Table I). This specimen was the only one to show significance in the TCNN alone. It is interesting that the only anemone having a long dark treatment was the only anemone not to show a significant change in SS2 burst rate resulting from the change in irradiance. The frequency of activity in the TCNN, SSI, and SS2 is higher in zooxanthellate anemones than in apozooxan- thellate individuals (P < , Duncan's Multiple Range Test). This may be manifested in the greater responsive- ness of the zooxanthellate anemones in behavioral studies (unpub. results), and also be related to the greater effect the dark treatment had on the burst rates, because all of the zooxanthellate anemones showed a significant effect of the treatment, whereas only three of the apozooxan- thellate anemones did. The burst rates in the three conducting systems were tested for correlat
