Abstract
Molluscs drifted on the coast of Yoron-jima in Amami Islands are studied. Drifted shells are collected from fifteen sites at ebb tide in late June, 2013. The Yoron molluscan fauna is composed of 102 species of shelled molluscs, 38 bivalves and 64 gastropods. The fauna is also dominated by rocky-shore species such as Barbatia fusca, Chama japonica, Strombus luhuanus, Cypraea caputserpentis, Conus flavidus etc. The fauna contains many coral reef elements such as Tridacna crocea, T.maxima, Cypraea annulus, C.moneta and C.mappa. From the specific composition, the fauna is assigned to tropical marine climate.
