Zusammenfassung
Symbiosis, the cohabitation of two or more different organisms, is represented across species as well as phyla. A unique symbiosis has developed in the marine environment between the phylum Cnidaria and members of the Division Dinophyta ("zooxanthellae"). The relationship is one of mutualism, as both organisms benefit from the relationship. Although cnidarians, such as sea anemones, hard and soft corals, scyphozoans, and hydrocorals, comprise the majority of hosts that take part in this symbiosis, some nudibranchs and sponges also contain endosymbiotic dinoflagellates. Alternatively, some cnidarians may contain chlorophyte endosymbionts. The symbionts are usually held with vacuoles inside the host endoderm cells (Glider et al., 1980; Trench, 1987), but they have also been found within the epidermis and mesoglea of some cnidarians.
