Molluscs and bottom sediments were collected by dredging in Sagami Bay off Hiratsuka in September 2016 and 2017. A total of 488 live specimens were collected, belonging to 36 species: 15 gastropods, 2 scaphopods, and 19 bivalves. Nine of them (Umbonium costatum , Phalium flammiferum , Orinella pulchella , Musculus cupreus , Pteria brevialata , Kellia japonica, Moerella jedoensis , Solen strictus , and Pitar noguchii ) were the first record in the investigation that started in 2010. All collected species except Modiolus flavidus , which is a tropical species, were warm-water species. The bottom sediment at around a depth of 5-10 m was medium to very fine grained sand containing 3.4-4.1% mud, and that at around a depth of 20-30 m was fine to very fine grained sand containing 7.0-9.1% mud. Around a depth of 40 m, the bottom sediment was fine to very fine grained sand containing 13.0% mud.
