We investigated the mineral coatings of six vent gastropod specimens (one each of the species Lepetodrilus nux, Cantrainea jamsteci, Desbruyeresia armata, Desbruyeresia marisindica, and two specimens of Alviniconcha marisindica from separate vent sites) from four different localities (Iheya North vent field, Okinawa Trough and Myojin-sho Caldera, Izu-Ogasawara Arc in the Pacific Ocean, and Kairei and Edmond vent fields on the Central Indian Ridge) using SEM/EDS and Raman spectroscopy. The resulting data show that the chemical composition of the coatings corresponds to the chemistry of vent fluids at the respective lScientific reportsDiversity of coatings on hydrothermal vent gastropods.PMC127562432021-1Bonk ASmrzka DHryniewicz KChen CLittle CTSBacal PfalseDiversity of coatings on hydrothermal vent gastropods.Shells of hydrothermal vent gastropods are often covered by inorganic coatings whose chemical composition, formation mechanisms, and possible function remain poorly understood.
