Molluscs are a diverse group of invertebrate animals belonging to the phylum Mollusca, characterized by soft bodies, often protected by a hard shell. They are known for their significant ecological and economic roles. Three examples of molluscs include snails (gastropods), clams (bivalves), and octopuses (cephalopods). Each group exhibits unique adaptations and lifestyles within various environments.

Many molluscs, such as snails, and also creatures like turtles and tortoises have shells.
There are six classes of mollusks. The Gastropoda, Monoplacophores,Polyplacophores(chitons) ,Scaphopods, Bivalves, andCephalopods. The Gastropoda are the most varied and the widest collected shells.
Gastropods, or slugs and snails, as opposed to molluscs with two shells which are bivalves.
Molluscs have a soft, unsegmented body that is typically covered by a protective shell made of calcium carbonate. This shell can vary in shape, size, and color among different mollusc species. In some molluscs, like octopuses and slugs, the shell is reduced or absent, and their bodies are often covered by a layer of skin known as the mantle, which can secrete additional protective materials. The mantle also plays a role in respiration and, in some species, locomotion.
Nudibranchs are members of the group of molluscs known as gastropods, specifically within the subclass Opisthobranchia. These marine snails are characterized by their lack of a shell and their vibrant colors and patterns.
