Biology     Glossary (e.g. epibenthic)

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 Maturity | Reproduction | Spawning | 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.
