Vestimentiferan tubeworms have no mouth or gut, and the majority of their nutritional needs are provided by endosymbiotic bacteria that utilize hydrogen sulfide oxidation to fix CO2 into organic molecules. It has been assumed that all vestimentifera obtain the sulfide, O2 and CO2 needed by the bacteria across the plume (gill) surface, but some vestimentiferans live in locations where very little sulfide is available in the seawater surrounding the plume. We propose that at least some of these vestimentiferans can grow a posterior extension of their body and tube down into the sea-floor sediment, and that they can use this extension, which we call the "root", to take up sulfide directly from the interstitial water.

Project: Determining growth rate in Tubeworms. Tubeworm growth and condition are a function of their exposure to vent effluent and vary significantly in different environments. Different morphological aggregates of tubeworms are a result of different microhabitat conditions and can be used as indicators of flow. Ridgeia piscesae are capable of both very fast growth rates as well as survival over extended periods with slow growth rates and long lives.

Schultz, Anja. There has been a lot of confusion about the systematic status of vestimentiferan tube worms (=Obturata) in the past. These animals have been switched continuously between the protostomes and the deuterostomes and their rank varied from class to subphylum to phylum. Recent molecular studies supported by some morphological data indicate that Vestimentifera as well as Pogonophora s. str. (also named Perviata) are derived polychaete annelids.
