...Peter R. Girguis; James J. Childress SUMMARY The hydrothermal vent tubeworm Riftia pachyptila is a dominant member of many hydrothermal vent communities along the East Pacific rise and is one of the fastest growing metazoans known. Riftia flourish in diffuse hydrothermal fluid flows, an environment...

...Bruce Shillito; Nadine Le Bris; Stéphane Hourdez; Juliette Ravaux; Delphine Cottin; Jean-Claude Caprais; Didier Jollivet; Françoise Gaill SUMMARY The shrimp Mirocaris fortunata is a hydrothermal vent species that is found at most vent-sites along the Mid-Atlantic Ridge. This endemic species...

... of Biologists Limited 2005 2005 hydrothermal vent development embryo pressure vessel polychaete temperature tolerance H 2 S environmental condition Organisms living in the hydrothermal environment are subject to great instability on various spatial and temporal scales( Haymon et al., 1993...

...Audrey M. Pruski; Aline Fiala-Médioni SUMMARY Symbiotic associations between marine invertebrates and sulphur-oxidising bacteria are a common feature in communities from sulphide-rich environments,such as those flourishing in the vicinity of hydrothermal vents. While the bacterial endosymbionts...

...Roy E. Weber; Stephane Hourdez; Francis Knowles; Francois Lallier SUMMARY Deep-sea hydrothermal vents probably provide the harshest physico-chemical conditions confronting metazoan animals in nature. Given the absence of information on hemoglobin (Hb) function in hydrothermal-vent vertebrates...

... ; N =5). This level is close to the oxygen content of 240±9μmol l -1 ( N =4) that we determined for deep waters surrounding the hydrothermal vent fields. The oxygen consumption rates( R ; expressed in μgO 2 h -1 ) were related to the shrimps mass ( M ; expressed in mg dry mass) following...

...P. R. Girguis; J. J. Childress; J. K. Freytag; K. Klose; R. Stuber SUMMARY Intracellular symbiosis requires that the host satisfy the symbiont's metabolic requirements, including the elimination of waste products. The hydrothermal vent tubeworm Riftia pachyptila and the hydrocarbon seep worm...

...) of the hydrothermal vent tubeworm Riftia pachyptila to acquire a general overview of nitrogen metabolism in this symbiotic organism. There were striking differences between the symbiont-containing trophosome tissue and other host tissues. High concentrations of ammonia, creatinine and, in particular, urate were found...

...Raymond W. Lee; Jonathan J. Robinson; Colleen M. Cavanaugh ABSTRACT Symbioses between chemoautotrophic bacteria and marine invertebrates living at deep-sea hydrothermal vents and other sulfide-rich environments function autotrophically by oxidizing hydrogen sulfide as an energy source and fixing...

...Shana K. Goffredi; James J. Childress; Nicole T. Desaulniers; Francois H. Lallier ABSTRACT Deep-sea hydrothermal vents are home to a variety of invertebrate species, many of which host chemosynthetic bacteria in unusual symbiotic arrangements. The vent tubeworm Riftia pachyptila (Vestimentifera...

...Shana K. Goffredi; James J. Childress; Nicole T. Desaulniers; Raymond W. Lee; Francois H. Lallier; Doug Hammond ABSTRACT Riftia pachyptila is the most conspicuous organism living at deep sea hydrothermal vents along the East Pacific Rise. To support its large size and high growth rates...
