| What is a Radula? | Rasping tongue. Used for feeding by molluscs contains iron and reinforced with magnetite. Also conveys food to digestive system. |
| Torsion | twisting during the larvae stages that cause the anus to be above the mouth of the gastropoda class |
| Single Shell Molluscs | Univalves- Gastropoda (snail & slugs) |
| Mantle | Also the Pallium. Made up of 2 skin folds, seperates the body from the shell. |
| Visceral Hump | The circulatory, respiratory, digestive and reproductive systems. |
| Head-foot depends on what for function | Depends on Muscle Activity |
| Two Shells or valves | Class Pelecypodia (bivalves) |
| Discussion: Round Worm life cycle | Eggs pass out feces, get injested by another host, hatch into juveniles, burrow through intestinal wall, intercirculation occurs, They can break out of lung, be coughed up into throat, and swallowed. They mature in 2 months feeding on intestinal contents. -results in allergic reactions, blockage, and gut infection. |

| adductor muscles function | controls the movement of shells |
| Anterior (umbo end) | side with the foot |
| Dorsal | Hinge Ligament side |
| Umbo | On anterior- Oldest part of shell |
| Hinge Ligament of clam | holds shells together/ makes them open |
| Anterior retractor muscle of Clam | Moves the foot |
