Mollusks: Gastropods, which include snails, and slugs, limpets, and bivalves:
The phylum of Mollusca is the second-largest group of invertebrate animals, accounting for nearly a quarter of the animals alive today. (Arthropoda is larger.) Mollusks are the largest marine phylum. The phylum includes gastropods, which include snails, and slugs, limpets, and bivalves; Cephalopods, which are squid and octopus; and five other classes of living mollusks and two extinct classes. Fossil records indicate they were alive during the Cambrian period some 500 million years ago. Mollusks are defined by having a mantled body, like a cloak over the main body organs, a similar nervous system, and having a saw-like tongue called a radula, except for bivalves. Mollusks with shells the mantle is actually forms the outer shell itself, and it can repair itself.
