Characteristics A separate window opensReferences

These are the waters in the vicinity of Kita-Daitojima Island (one of the Daitojima Islands), located about 360 km east of Okinawa Island. A raised atoll island formed by a raised coral reef, like Minami-Daitojima Island, Kita-Daitojima is surrounded by seas that are very deep. 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).
