The video provides an overview of molluscs, highlighting their lack of a spine and soft body. It describes the radula, a tongue-like organ with teeth, and categorizes molluscs into three main groups: gastropods, bivalves, and cephalopods. Gastropods, including snails and slugs, are the most diverse, with snails typically having spiral shells. Bivalves, such as clams, oysters, and mussels, have two shells. Cephalopods, like squid and octopus, live in salt water and lack shells.
