Hexacorallia

Cold-water corals build up reef structures or coral gardens and play an important role for many organisms in the deep sea. Climate change, deep-sea mining, and bottom trawling are severely compromising these ecosystems, making it all the more important to document the diversity, distribution, and impacts on corals. This goes hand in hand with species identification, which is morphologically ...

Introduction to the Octocorallia. Although commonly called "soft corals," the Octocorallia are not close relatives of the Scleractinia, or "true corals" living today.Unlike true corals, which have hexaradial symmetry, octocorals have eightfold radial symmetry -- count the tentacles on the polyps of this Muricea, from the Bahamas.Sea anemones constitute a large group of the Hexacorallia (Barnes, 1974; Borradaile et al., 1977).They are solitary polyps and are considerably larger and heavier than the polyps of hydrozoans (Figs 5.1 and 5.15).Most sea anemones range from 1.5 to 5.0 cm in length, with a diameter varying from the size of a dime to that of a half dollar.However, there are species of Goniactinia, Edwardsia and ...Jan 9, 2013 · The diversity of zoanthids described or observed during this study is comparable to levels of diversity found in shallow water tropical coral reefs, symptomatic of the lack of biological exploration and taxonomic studies of the diversity of seamount hexacorals.
