2. Symmetry in mollusks Bilateral symmetry

3. How do mollusks move? Most – muscular foot Tentacles Shells http://gotmuscle.weebly.com/mollusca.html

4. Nervous system Present nervous system Nerve bundles Ganglia Squid-large developed eyes similar to human

5. Digestive System Siphon system Waste

6. Excretory system Nephridium Kidney One-way

7. Circulatory system Cephalopods-closed Gastropods and Bivalves-open

8. Respiratory System Siphons Gills

9. Support of skeletal system Outer shell Soft body Muscular foot Tentacle's

10. Reproductive system Sexually Gonad

11. Three main classes Gastropod/Univalves Bivalves Cephalopods http://www.isgs.uiuc.edu/outreach/geology- resources/gastropods http://www.thecanadianencyclopedia.ca/en/ article/mollusc/ http://w3.shorecrest.org /~ Lisa_Peck/MarineBi o/syllabus/ch7invertebrates/Invertwp/inv_class _of_06_wp/jiali_cuttlefish/classification.htm

12. Gastropods/Univalves Largest group of mollusks’ Snails, conchs (univalves), abalones, whelks, sea slugs, and garden slugs On shell (except slugs) rhythmic contraction of muscular foot Use radula to scrape up food islandcolors.comwww.slugwatch.co.uk www.caribbeanfmc.com

13. Bivalves Clams, oysters, and scallops Two-part, hinged shell joined by strong muscles Close shell by contracting muscles Well adapted to living under water Clams move with their foot Scallops open and close shell rapidly trueoyster.com tbep.org

14. Cephalopods Most specialized and complex group Squid, octopuses, cuttlefish, and chambered nautiluses Foot divided into many tentacles All live in water Well developed nervous system Only mollusks with closed circulatory system www.practicalfishkeeping.co.uk www.arkive.org

15. Why are cephalopods mollusks? Similar internal structures U shaped digestive track mantle Used to have a shell Now kind of internal userwww.sfsu.edu

18. Mollusks are referred to as “soft-bodied” because… Composed of shell and fleshy body The shell protects the soft body Fleshy part divided into foot & visceral mass Organs stored soft, fleshy visceral mass

19. The real meaning Gastropod: “stomach foot” Cephalopod: “head foot”

20. How pearls are created In oysters, clams, and mussels Foreign substance in shell and mantle Mantle creates substance to protect itself Mantle layers irritant in mantle substance Eventually results in a shell
