  7. Mollusks • Characteristics of Mullosks Definition Body Structure Circulatory System Gastropods Bivalves Obtain food Obtain Oxygen Movement Reproduction Adaptations • Open Circulatory System A circulatory system in which the heart pumps blood into open spaces in the body and blood is not confined to blood vessels.

  8. Mollusks • Characteristics of Mullosks Definition Body Structure Circulatory System Cephalopods Obtain food Obtain Oxygen Movement Reproduction Adaptations • Closed Circulatory System A circulatory system in which the heart pumps blood through blood vessels.

  9. Mollusks • Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Gastropods Obtain Oxygen Movement Reproduction Adaptations • Radula A flexible ribbon of tiny teeth in mollusks.

  10. Mollusks • Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Bivalves Obtain Oxygen Movement Reproduction Adaptations • Filter feed • Food particles stick to mucus, then moved to mouth by cilia
