The Calyfield clam field was the western-most known vent field on the Galápagos Rift when discovered 89.6°W.  The field hosts a large vesicomyid (Calyptogena magnifica) clam, mussel (Bathymodiolus thermophilus), and endemic sponge community that covers an approximately 60 m x 60 m area.  In 2002, extinct high-temperature sulfide chimneys were discovered several hundred meters northeast of Calyfield.
