GROWTH OF HOST AND ZOOXANTHELLAE 113. xanthellae may be limited by available space or physiolog- ical parameters associated with the size of the host cell. Larger host cells contained more zooxanthellae than smaller host cells, and the number of zooxanthellae residing inside of a digestive cell was directly correlated with the relative volume of the cell (Fig. 4). The average number of zoo- xanthellae in each hydroid polyp, including 1-2 mm of stalk, was ± (mean ± SD) X 105 (;i = 15 different colonies). Growth Growth

Growth Growth of a colony of Mvrioneina was surprisingly con- stant. When maintained in the laboratory for 1 week, hy- droids grew an average of ± mm stolon length/d (/( = 15) for each piece of stolon. There was no correlation between growth rate and initial size of the colony (range 1-15 polyps). Both laboratory-maintained and field-moni- tored colonies roughly doubled their number of polyps over an 8-day period (Fig. 5), regardless of colony size. d.
