Trophosome is an organ found in the coelomic cavity of the giant tube worm, Riftia pachyptila. Symbiotic bacteria in the trophosome oxidize sulfur found in the tube worm's environment and produce organic molecules that the worm can use as an energy source.[Ref 1] This process is known as chemosynthesis.
