This occurrence represents a significant range extension. Transmission electron microscopic observations of the gill tissue revealed dense bacteria in the epithelial cells. A molecular phylogenetic analysis strongly indicated that these bacteria are thioautotrophs closely related to the thioautotrophic symbionts associated with Solemya reidi and Acharax johnsoni. Analysis of carbon and sulfur isotopes of soft tissues of S. pervernicosa proved that this bivalve depends nutritionally on thioautotrophic symbionts. However, it is not clear at present whether the symbiont is transmitted vertically, as with some other chemosynthetic bivalves, or environmentally.}, pages = {27--37}, title = {Solemya pervernicosa Lives in Sediment underneath Submerged Whale Carcasses: Its Biological Significance}, volume = {68}, year = {2009} }
