Hermatypic corals of Urasoko Bay, Ishigaki Island, were listed in systematic order. A total of 234 species belonging to 59 genera and 16 families were recorded from field studies carried out during 1994-1996. Although Urasoko Bay is a very small bay with an area of only 2.6 square-km, the number of hermatypic coral species found in the bay sums up to approximately 70 percent of that found in the whole Yaeyama Islands, and 63 percent of that in the entire Japanese waters. High species diversity (richness of species) observed in such a small bay is considered to be caused by the two factors: compactly aggregated diverse coral reef topography and diverse physico-chemical environmental conditions
