Chemosynthic clams host sulfide-metabolizing bacteria in their gills. The bacteria produce food and enzymes for clam to live and grow.
Other bacteria metabolize methane to SCO2 which can combine with Ca2+ from sea water to make CaCO3. Carbonate crusts are found in many places, commonly associated with faults. Areas with carbonate crusts are likely fossil vent sites.
