Gastropods (such as slugs and snails) and bivalves (such as clams and mussels) are both invertebrate mollusks.
Shellfish that are not bivalves include crustaceans and cephalopods. Crustaceans, such as shrimp, crabs, and lobsters, have an exoskeleton and jointed limbs. Cephalopods, like octopus and squid, are known for their advanced nervous systems and ability to change color. Unlike bivalves, which have two hinged shells, these groups have different anatomical structures and classifications.
Bivalves, univalves, and cephalopods are all types of mollusks. So are gastropods.

Mollusca
No; squid, cuttlefish, octopuses, and nautiluses are mollusks, and more specifically, cephalopods.

Mollusks that possess a radula include gastropods (such as snails and slugs), bivalves (in some cases, like certain primitive species), and cephalopods (like squids and octopuses). The radula is a unique feeding organ that functions like a tongue, equipped with tiny teeth to scrape food from surfaces. However, many bivalves lack a radula, as they primarily filter feed. Overall, the radula is most commonly associated with gastropods and cephalopods.
Gastropods: snails. Gastro means something like 'stomach' or 'belly' and 'pod' means 'foot'. Cephalopods: octopusi. Cephalo means something like 'head'. Bivalves are molluscs with two clasping shells like a clam and univalves have only one.
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.
MC Scientific name: Mollusca Types The three main types of mollusks are gastropods, bivalves, and cephalopods. Gastropods, like slugs and snails, can live on land or in the water.
