Alviniconcha is a genus of deep water sea snails, marine gastropod mollusks in the family Provannidae.[1] These snails are part of the fauna of the hydrothermal vents in the Indian and Western Pacific Ocean.[2] These and another genus and species within the same family (Ifremeria nautilei) are the only known currently existing animals whose nutrition is derived from an endosymbiotic relationship with a member of bacteria from phylum Campylobacterota (formerly Epsilonproteobacteria) and Gammaproteobacteria, occurring as endosymbionts within the vacuoles of Alviniconcha ctenidia (or molluscan gills).[3] All species of Alviniconcha are thought to be foundational species found near hydrothermal venting fluid supplying their bacterial endosymbionts with vent derived compounds such as hydrogen sulfide. These snails can withstand large variations in temperature (5 - 33 °C),[4] pH, and chemical compositions.
