Contraction may be a means of producing a low oxygen concentration in the coelenteron, resulting in lower metabolic rates and in savings of energy or carbon regardless of the external oxygen level (Sebens, 1987b).
Virtually all zooxanthellate cnidarians appear to expel some of their symbiotic dinoflagellates from their coelenteron on a daily basis (e.g., Reimer, 1971; Hoegh-Guldberg et al., 1987), whereas mass expulsion of zooxanthellae has been attributed to severe osmotic or thermal stress (Goreau, 1964; Jokiel and Coles, 1977, 1990; Jaap, 1979; Glynn, 1983).
Amoebocytes were extracted from the mesenteric filaments, located at the base of the coelenteron, by making an incision into the center of the pedal disc and excising the filaments into a sterile 15-ml plastic centrifuge tube (Smith and Hutton, 1995).
