Mollusks can be segregated into seven classes: Aplacophora, Monoplacophora, Polyplacophora, Bivalvia, Gastropoda, Cephalopoda, and Scaphopoda. Gastropods are less intelligent, and they are slow-moving animals. These animals use a "radula" which is a tonguelike organ with rows of teeth to obtain food. Comparing Bivalves and Gastropods Students should explain the following: Seashells are made by animals called mollusks. Cephalopods also have the largest brains of .
