Many different animals are under the name molluscs. Scallops and clams are a special kind of mollusc called bivalves. Bivalves have two shells sandwiched together. They eat plankton and algae.
Squid and octopi are also molluscs. They are a lot bigger than bivalves and a lot smarter. They eat fish, crustaceans and other molluscs. The giant squid can grow to be 50 feet long! There are old stories about giant squids attacking ships!
