Molluscs and Our Ecology Zebra Mussels
Classes of Molluscs • 3 classes of molluscs we will be examining: • Gastropods (Gastropoda) • Cephalopods (Cephalopoda) • Bivalves (Bivalvia)
Classes of Molluscs: Gastropods GASTRO = STOMACH; POD = FOOT
Classes of Molluscs: Cephalopods CEPHALO = HEAD; POD = FOOT
Classes of Molluscs: Bivalves BI = TWO; VALVE = SHELL
