Multiple symbiotic partnerships are common in scleractinian corals, but not in octocorals: Comment on Goulet (2006)

analyzed data on 442 coral species from 43 studies and found that 340 species (77%) hosted Symbiodinium from only one clade. We compiled data from the same sources, but to avoid inflating the species count excluded coral species reported only to the generic level ('sp.' or 'spp.'), except where they could be unambiguously assigned to a single species not otherwise represented in the dataset. We also did not include T. L. Goulet et al. (unpubl.), for which no details were provided in Goulet (2006; see her Table Our analysis contained 307
