Abstract
Observations on fine structure, metabolic enzymes and stable isotope ratios of several species of Pogonophora from a wide range of habitats suggest that members of this enigmatic phylum of worm-like deep-sea animals use internal chemoauto -trophic bacteria as part of their nutrition, allowing them to exploit scarce nutrient and energy resources.
