NMSAS - giant clam

National Marine Sanctuaries

Giant clams are overharvested in many parts of the ocean, but Rose Atoll in National Marine Sanctuary of American Samoa is known for its high density of these enormous bivalves. Much like corals, giant clams are home to symbiotic photosynthetic algae that produce an important source of food for the clams.
