Reef corals are symbioses that consist of an animal partner and dinoflagellate algae commonly known as zooxanthellae. This delicate association functions only within a very narrow range of environmental conditions in shallow tropical seas (Wells 1957). The symbiosis is thought to have developed as a means of coping with very low concentrations of nutrients in tropical marine waters (Muscatine and Porter 1977). This association provides benefits to both partners. The zooxanthellae are primary producers and supply their coral hosts with photosynthetic products vital to meeting their energetic requirements. In return, the zooxanthellae receive living space and nutrients in the form of waste metabolic products from the host. The tight cycling within the symbioses facilitates the high productivity and calcification rates observed in corals (Falkowski et al. 1984).
