What are Cephalopods?

Cephalopods are a class of mollusks. They sit within the phylum Mollusca and are distinct from other mollusks like gastropods (snails and slugs) and bivalves (clams and oysters). Cephalopods are known for a prominent head with arms or tentacles around it, a highly developed nervous system and eyes, and often an internal or reduced shell. They typically move by jet propulsion using a siphon. This group includes octopuses, squids, cuttlefish, and nautiluses. So, cephalopods are a specific class of mollusks, not the broader mollusk category.
