Note
Coral bleaching involves the loss of symbiotic dinoflagellates (zooxanthellae) from reef corals and other cnidarians and may be a stress response of the host, algae or both. To determine the roleof zooxanthellae in the bleaching process, aposymbiotic sea anemones from Bermuda (Aiptasia pallida) were infected with symbionts from other sea anemones (Aiptasia pallida from Florida, Bartholomea annulata and Condylactis gigantea).
