Main Ref.	Andersen, A.C., S. Hourdez, B. Marie, D. Jollivet, F.H. Lallier and M. Sibuet, 2004
Remarks	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).
