Molluscs

Molluscs, a large phylum of invertebrate animals, are the largest marine phylum, including about 23% of all marine organisms. Cephalopods, including the octopus, are among the most neurologically complex invertebrates. Gastropods (snails and slugs) are the most numerous molluscs, about 80% of the total.
