Giant clams up to 1 foot long thrive in the crevices around seafloor pillow lava, which vent hydrothermal fluids with chemical nutrients. This vent site on the Galápagos Rift, discovered in 2002, is called “Calyfield” after the clam (Calyptogena magnifica). The 2002 expedition was the first time NOAA Ocean Exploration sponsored work around the Galapagos.
