  16. Classes of Molluscs: Gastropods GASTRO = STOMACH; POD = FOOT

  17. Classes of Molluscs: Cephalopods CEPHALO = HEAD; POD = FOOT

  18. Classes of Molluscs: Bivalves BI = TWO; VALVE = SHELL

  19. Your Way vs. Science’s Way Add on to your notes the answers to these questions: Was your way of classifying molluscs into three groups similar or different to the way that scientists do it? In what ways are they similar or different?
