Molluscs include the familiar snails, garden slugs, and beautiful sea slugs (class Gastropoda), the clams, oysters, scallops, and mussels (class Bivalvia), the active octopuses, squid, cuttlefish and Nautilus (class Cephalopoda) as well as some less familiar groups such as the classes Aplacophora (shell-less worm looking things called solenogasters), Caudofoveata (small shell-less deep-sea worm like things), Monoplacophora (living fossils—only 8 or so species), Polyplacophora (chitons) and Scaphopoda (tusk shells). In terms of numbers of species, Mollusca is the second largest phylum of invertebrates (Arthropoda is the largest). Molluscs are one of the most noticeable groups of invertebrates as well—their attractive shells are collected and many species are consumed as food (hungary yet?).
