Characteristics A separate window opensReferences

These are the waters in the vicinity of Minami-Daitojima Island (one of the Daitojima Islands), located about 400 km east of Okinawa Island (directly to the south of Miyazaki Prefecture). A raised atoll island formed by a raised coral reef, its coats is a sheer precipice. The seas around the island are very deep, reaching depths of 1000 m about 2 km from shore. In these waters live high concentrations of rayed wheel limpet, a species distributed in few locations in Japan, and Tectarius (Echininus) spinulosus, a species that might not be recorded elsewhere, can be seen here too (Kurozumi, personal communication).
