Molluscs drifted on the coast of Okinoerabu-jima in Amami Islands are studied. Drifted shells are collected from ten sites at ebb tide in late January, 2015. The Okinoerabu molluscan fauna is composed of 115 species of shelled molluscs, 32 bivalves and 83 gastropods. The fauna is also dominated by rocky-shore species such as Barbatia fusca, Chama japonica, Nerita albicilla, Cypraea caputserpentis, Conus ebraeusetc. The fauna contains many coral reef elements such as Tridacna maxima, Cypraea annulus, and C.moneta. From the specific composition, the fauna is assigned to tropical marine climate.
