Those animals which were collected hourly for 24 hour periods and had their lateral ciliary activity assessed showed a diurnal ciliary rhythm (Fig. 1). For June 10 and 21 the activity appeared to be independent of tidal cycles, but rose and fell in coordination with the daily rise and fall of the water temperature and the sun. For August 23 no ciliary rhythmicity was observed, and the water temperature remained fairly constant. To examine environmental influences more closely, groups of animals were collected between June 6 and July 27, on 16 different occasions at different tidal periods, and their beating rates were plotted against the tidal period and nperature at which they were collected (Fig. 2). Examination of these figures reveals that a linear regression with a correlation coefficient of can be plotted.
