Mollusks have many cell layers 2. They have tissues and organs, 3.They have no body cavity or hollow place 4. They have a nervous system, open circulatory system, and kidneys. 5. Some have gills for breathing in water. 6. Some have shells. 7. Some have a muscular foot for movement.  Samples:  6A = Genus Helix (land snail) There are two samples to see.
