Digestive and Circulatory Systems

Oysters and Scallops are two common types of Bivalves. They are both filter feeders, but only one of them moves around while the other stays mainly in the same place for all of its life. Each of these animals are rather important to the worlds ecosystem in that they are harvested for food and pearls. While both of these organisms are found in the same class (Bivalvia) they do differ greatly.
