Generally the bivalves are filter feeders. As you look at a bivalve in the water and undisturbed one will see a slight protrusion of its siphons (incurrent and excurrent). Water enters the creature and passes over under and through the gills. These are covered with cilia which conduct the bits of detritus (microscopic organic debris in the water) to the "mouth" and into the digestive system where it will be hydrolyzed (digested) and absorbed and used as needed.
