Corliss and colleagues explored Galápagos Rift hot springs with the submersible Alvin and found animal communities that appear to get their entire energy supply from chemosynthesis by sulfur-oxidising bacteria rather than photosynthesis.
As reported in: Corliss, Dymond, Gordon et al. (1979). Submarine Thermal Springs on the Galápagos Rift. Science. doi:10.1126/science.203.4385.1073
Abstract only
Felbeck found high levels of sulfur-energy and carbon-fixing (Calvin cycle) enzymes in the trophosome of the mouthless tube worm Riftia pachyptila, consistent with an autotrophic way of feeding.

Cavanaugh and colleagues suggested, from tissue and enzyme evidence, that Riftia tube worms host chemoautotrophic sulfur-oxidising bacteria as symbionts.
