The vestimentiferan Paraescarpia echinospica is widely distributed in the cold seeps and methane seeps of the western Pacific Ocean, and relies on their endosymbiont bacteria as a source of energy and organic carbon. It's gutless and depends entirely on its endosymbiotic sulfide-oxidizing chemoautotrophic bacteria for nutrition. Its mechanisms of host–symbiont cooperation in energy production and nutrient biosynthesis and utilization have recently been documented through a study of its endosymbiont genome and metaproteome.
