A heterodont bivalve mollusk Calyptogena magnifica, from the East Pacific Rise and the Galápagos Rift hydrothermal vent areas, contains abundant hemoglobin in circulating erythrocytes. Calyptogena magnifica is a species of giant white clam found clustered around hydrothermal vents at abyssal depths in the Pacific Ocean. Calyptogena spp. bivalve and vestimentiferan species; depend on sulfur bacterial symbionts. Sexes are separate (dioecious) and fertilization is external and non-specific. They are the prey of Blind crabs and, Vent octopus. Deze pagina is voor het laatst bewerkt op 1 feb 2016 om 23:34. The Calyptogena magnifica chemoautotrophic symbiont genome.

Calyptogena magnifica saline was prepared on the basis of average con-centrations of inorganic salts measured in fresh C. magnifica serum by ion chromatography (Sanders and Childress 1991). The Calyptogena magnifica (Bivalvia: Vesicomyidae) symbiont, Candidatus Ruthia magnifica, is the first intracellular sulfur-oxidizing endosymbiont to have its genome sequenced, revealing a … Calyptogena magnifica. mt-II clams from deep sea vents on the Juan de Fuca Ridge (Goffredi et al., 2003, Stewart et al., 2008). waves to move them around. Upload your photos Google image | No photo available for this species. cold seeps also harbor. Unlike typical clams that are found in sediments, these giant clams (Calyptogena magnifica) live on a hard pavement of volcanic rock near hydrothermal vents. No drawings available for this family. Clams As recorders of ocean ridge volcanism and hydrothermal vent field activity. The clam's blood also contains a separate component that binds hydrogen sulfide and transports this essential metabolite to internal symbionts in the gill region. The saline was titrated to pH 7.5 with NaOH before use. However, small tubeworms and Riftia pachyptila mussels (Bathymodious thermophilus) were also found, indicating recent and active colonization (Shank et al., 2012). The hydrothermal vent clam Calyptogena magnifica (Bivalvia: Vesicomyidae) depends for its nutrition on sulfur-oxidizing symbiotic bacteria housed in its gill tissues. The hemoglobin is tetrameric and has a relatively high oxygen affinity, which varies only slightly between 2 degrees and 10 degrees C. The presence of hemoglobin in the clam may facilitate the transport of oxygen to be used in chemoautotrophic hydrogen sulfide metabolism. Chemoautotrophic endosymbionts are the metabolic cornerstone of hydrothermal vent communities, providing invertebrate hosts with nearly all of their nutrition. on 1997/09/02 Fujikura, K., Okutani, T. and T.
