Tubeworms do not eat. The giant tube worm (Riftia pachyptila) lives in a symbiotic relationship with sulfur-oxidizing bacteria.
The two closely related deep-sea tubeworms Riftia pachyptila and Tevnia jerichonana both rely exclusively on a single species of sulfide-oxidizing endosymbiotic bacteria for their nutrition. Tubeworm larvae have a mouth, and, during the process of finding a place to settle, they eat the bacteria that will remain with them for the rest of their lives. The plume has a large, highly vascularized surface which allows for the exchange of metabolites between R. pachyptila and the environment. Significance: The Giant Tube Worm (Riftia pachyptila) is a very unique species adapted to survive in one of Earth's most extreme and inhospitable environments. of Delware Marine Studies. Riftia pachyptila is a giant tubeworm of typically one to two meters in length that inhabits the volcanic deep sea vents of the Pacific Ocean. The Riftia pachyptila is one of the longest creatures of the Annelida phylum and can grow as long as 8 ft (2.5 m). Mobile (errant): crawl over substrates or swim. The giant tube worm (Riftia pachyptila or tubeworm) are animals without a mouth, gut and legs that depend on microorganisms for food.Giant tube worms are seen everywhere in the pacific ocean where deep sea hydrothermal vents have been revealed.
