Riftia tubeworm
)
WebSpecies colonizing new deep-sea hydrothermal vents along the East Pacific Rise show a distinct successional sequence: pioneer assemblages dominated by the vestimentiferan tubeworm Tevnia jerichonana being subsequently invaded by another vestimentiferan Riftia pachyptila, and eventually the mussel Bathymodiolus thermophilus. Riftia pachyptila, commonly known as the giant tube worm and less commonly known as the Giant beardworm, is a marine invertebrate in the phylum Annelida (formerly grouped in phylum Pogonophora and Vestimentifera) related to tube worms commonly found in the intertidal and pelagic zones. R. pachyptila … See more R. pachyptila was discovered in 1977 on an expedition of the American bathyscaphe DSV Alvin to the Galápagos Rift led by geologist Jack Corliss. The discovery was unexpected, as the team was studying … See more Isolating the vermiform body from white chitinous tube, a small difference exists from the classic three subdivisions typical of phylum See more A wide range of bacterial diversity is associated with symbiotic relationships with R. pachyptila. Many bacteria belong to the phylum Campylobacterota (formerly class Epsilonproteobacteria) as supported by the recent discovery in 2016 of the new species Sulfurovum … See more In deep-sea hydrothermal vents, sulfide and oxygen are present in different areas. Indeed, the reducing fluid of hydrothermal vents is rich in sulfide, but poor in oxygen, whereas sea water is richer in dissolved oxygen. Moreover, sulfide is immediately oxidized by … See more R. pachyptila develops from a free-swimming, pelagic, nonsymbiotic trochophore larva, which enters juvenile (metatrochophore) development, becoming sessile, and subsequently acquiring symbiotic bacteria. The symbiotic bacteria, on which … See more The discovery of bacterial invertebrate chemoautotrophic symbiosis, particularly in vestimentiferan tubeworms R. pachyptila and then in vesicomyid clams and mytilid mussels revealed the chemoautotrophic potential of the hydrothermal vent … See more Unlike metazoans, which respire carbon dioxide as a waste product, R. pachyptila-symbiont association has a demand for a net uptake of CO2 … See more
