This paper presents a check list of marine mollusks collected at Flexeiras beach, Itacuruçá Island, Rio de Janeiro state, Brazil. A total of 41 species, belonging to 36 genera and 28 families were identified. Bivalves showed the highest species richness. Our results suggested that the presence of rock fragments in sandy beaches enhances environmental heterogeneity and enable the settlement and recruitment of both sandy beach and rocky shore organisms increasing the biodiversity.
