Molluscs are animals which have no backbone (invertebrates) and no exoskeleton. These include snails (they have an outer shell but it isn't an exoskeleton) slugs (no shell, no exoskeleton, no bones) octopuses (they have no bones. They aren't fish because all fish have bones.) Sea snails and periwinkles are just other types of snail.
