Based on the results of monitoring macroepibenthic studies in April-October 2019-2022, modern composition of shell-bearing gastropods and bivalves inhabiting the intertidal and upper subtidal zones of Vostok Bay (Sea of Japan) has been studied.The list includes 40 species of Gastropoda and 25 -Bivalvia.Of these, Fluviocungula elegantula (A.Adams, 1861), Liostomia minutissima Golikov in Golikov et Scarlato, 1967 and Odostomia culta Dall et Bartsch, 1906 are new species for the malacofauna of Vostok Bay.Information about the species occurrence, ecology, abundance indicators and distribution is given.A high degree of association of these taxonomic groups and macrophyte thickets was revealed.The peculiarities of the malacofauna in local areas of Vostok Bay with different environmental conditions are discussed.
