molluscs are a group of animals that include snails,
clams and squid. most molluscs have a muscular 'foot',
which they use to move around

a heavy shell, such as this helmet shell, protects the soft
body of a snail. when threatened, the snail retreats into
its shell. this is a spiral shell but some are cone-shaped

nudibranch is a soft-bodied sea slug that have no shell

without a shell for protection, he uses poison to
defend himself against predators

his brightly colored body will warn other animals
that he's poisonous

giant clam is a bivalve - a snail with two shells that are
hinged together. clams stay in one place on the reef,
sucking water into their body & filtering out plankton

their color come from algae, which live in their cell
& provide the clams with food

flamingo tongue snails are coral eaters. as they crawl
over the coral, their feet release digestive juices

the juices dissolve the polyps and the snails
absorb the nutrients through their foot

the largest giant clams grow to more than a meter across,
weigh more than 200 kg & can live for up to 100 years
