Length at first maturity / Size / Weight / Возраст
половая зрелость: Lm ?  range ? - ? cm Max length : 200 cm TL самец/пол неопределен; (ссылка 99941); наибольший вес (опубликованные данные): 650.00 g (ссылка 99323)
Depth range based on a locality (Ref. 7675); to be replaced with a better reference. The tube length and diameter can measure up to 3 m and 5 m, respectively; but the length of the worm in the 3 m tube is only 1 m (Ref. 99323). Abyssal (Ref. 19). It lacks a functional digestive system and derives its nutrition from vent plumes through an endosymbiotic relationship with chemoautotrophic bacteria stored in a specialized organ called a trophosome (Ref. 99323).
Life cycle and mating behavior
половая зрелость | размножение | нерест | Eggs | Fecundity | Larvae
Spawning is intermittent, not continuous and lasts an hour; release of gametes are propelled upward by withdrawal of the worm into its tube. Neutrally buoyant sperm bundles are expelled forcefully enough to be dispersed over a field of tubeworms; the sperm bundles swim and attach to females, somehow mediating a spawning response in the female; fertilization occurs internally immediately before spawning or externally (within the vestimental chamber?) just after release of the eggs; accumulated eggs are forcefully ejected into the water column where, negatively buoyant, they spend a short period near the site of release; advective conditions of the turbulent, warm-water vent environment disperse gametes and developing larvae away from the adult population.
