Turbinaria (coral) : ウィキペディア英語版 | Turbinaria (coral)
''Turbinaria'' is a genus of colonial stony corals in the family Dendrophylliidae. Common names for this genus include disc coral, scroll coral, cup coral, vase coral, pagoda coral and ruffled ridge coral. These corals are native to the Red Sea, Indian Ocean, Japan and the south Central Pacific Ocean. ==Characteristics== Members of this genus may be massive, laminar, columnar or foliaceous, but foliaceous is the most common form. They may form plates, discs or tiered structures, usually with the corallites (skeletal cups in which the polyps sit) only on one surface. The coralites have porous walls and may be sunk into the surrounding coenosteum (skeletal tissue), or form tubular raised mounds. The septa (vertical blades in the corallites) are short and arranged neatly and the columella (central point where the septa join) is broad. The coenosteum is dense and heavy. Most species are nocturnal, with the polyps expanding only at night, but ''Turbinaria peltata'' is an exception to this.〔〔
