The giant tube worm, Riftia pachyptila (phylum Vestimentifera), is known only from four widely separated sulfide-rich deep-sea hydrothermal vent systems. The association between the vent tubeworm Riftia pachyptila and its endosymbiont Candidatus Endoriftia persephone has become a model system for symbiosis research in deep-sea vestimentiferans, while markedly fewer studies have investigated symbiotic relationships in other tubeworm species, especially at cold seeps. The Candidatus Endoriftia persephone is a facultative R. pachyptila symbiont and has been shown to be a mixotroph, thereby exploiting both Calvin Benson cycle and reverse TCA cycle (with an unusual ATP citrate lyase) according to availability of carbon resources and whether it is free living in the environment or inside a eukaryotic host.
