Description:
We describe the habitat as "hydrothermal vent" ENVO term http://purl.obolibrary.org/obo/ENVO_00000215 for those taxa for which we are confident that the adults live at a hydrothermal vent, otherwise NotDetermined. We are not describing the sampling event habitat per se, thus deviating from the definition of Darwin Core term http://rs.tdwg.org/dwc/terms/habitat
