| Abstract: | Total fatty acid compositions of colonies of two hermatypic, reef-building corals collected during the day-time over a depth range of 21 m were determined to assess the effect of depth-related environmental factors upon the lipid content of these organisms. No systematic changes were found, suggesting a steady-state balance between algal and animal lipogenesis in these symbiotic partnerships. Stephanocoenia michelinii, a day and night feeder, contained lipids indicative of external dietary sources such as copepods, whereas Montastrea annularis, a night feeder, did not. |
