The secret to longevity in tubeworms

...e seep where the worm lives. These chemoautotrophs use energy from hydrocarbons to reduce sulfate to sulfide, which L. luymesi absorbs through its unique "roots," extensions of its body that it tunnels into the sediments. However, current measurements of sulfide and sulfate fluxes in the water near the v...
