Up close: Gills. The clam gills play an interesting role in the clam's survival. The gills have two functions in two separate systems of the clam. For the digestive system, the gills aide in digestion through separating silt from the nutrition and aids in the respiratory system through providing oxygen to the clam.
Clams are members of the class Bivalvia, or mollusks with a bivalved shell (having two separate sections). More than 15,000 living species of bivalves are known, of which about 500 live in freshwater; the others occur in all seas. Most species, including the quahog, geoduck, and soft-shell clam, are edible.
