Molluscs drifted on the coast of Okushiri Island are examimed. Drifted shells are collected from eight sites in early May 2012 and late June to early July 2017. The Okushiri mollus can fauna is composed of 75 species of shelled molluscs, one polyplacophor, 28 gastropods and 46 bivalves. The fauna is almost dominated by cold-water species and eurythermal species. The fauna contains seven warm-water species such as Phalium flammiferum, Spondylus cruentus and Solecurtus dunkeri etc. Appearance of warm-water species are attributed to the combination of the Tsushima warm current, which transports warm-water taxa northward and especially the higher trend sea surface temperatures （SSTs） in winter.
