Siboglinid (IMAGE) UiT The Arctic University of Norway Caption This image shows a chemosymbiotic worm (Siboglinidae) from Bjørnøyrenna crater field. The siboglinids are dependent on microbes for their nutrition. This successful symbiosis relies on the microbes to convert the methane to organic material that provides energy for the worms.
