The size of a patch of tube worms surrounding a vent can span tens of metres, and individuals can reach a length of 3 m (9 ft 10 in).

Pełniejszy materiał źródłowy / excerpt

Riftia is a monotypic genus of polychaete annelid worms in the Siboglinidae family, which contains the sole species Riftia pachyptila, commonly known as the giant tubeworm or giant beardworm. R. pachyptila is found in association with geologically active regions of the deep sea. Riftia worms are sessile and are found clustered together in large colonies around deep-sea hydrothermal vents in the East Pacific Rise and the Galapagos Rift. The size of a patch of tube worms surrounding a vent can span tens of metres, and individuals can reach a length of 3 m (9 ft 10 in). R. pachyptila has the fastest growth rate of any known marine invertebrate, and have been known to colonize a new site, grow to sexual maturity, and increase in length to 4.9 ft (1.5 m) in less than two years. Adult Riftia worms lack a digestive system and rely on their symbiotic relationship with chemotrophic sulfur-oxidising bacteria to provide them with energy. The hydrothermal vent habitat in which Riftia lives provides a natural ambient temperature ranging from 2–30 degrees Celsius (36–86 °F) and emits large amounts of chemicals such as hydrogen sulfide that are utilised by the tube worm for bacterial chemosynthesis.

DNA-DNA Solution Hybridization Studies of the Bacterial Symbionts of Hydrothermal Vent Tube Worms ( <i>Riftia pachyptila</i> and <i>Tevnia jerichonana</i> ). The giant tube worm, Riftia pachyptila (phylum Vestimentifera), is known only from four widely separated sulfide-rich deep-sea hydrothermal vent systems. This invertebrate is nourished by intracellular, chemoautotrophic bacterial symbionts which reside in a specialized trophosome tissue. The symbiont has not been cultured independently and is believed to be acquired de novo by host larvae of each generation. In the current study, R. pachyptila symbiont DNA was purified from the two most distant sites on the basis of its difference in d…
