What classification includes organisms like octopuses and squids?

The classification that includes organisms like octopuses and squids is Mollusks. This group is characterized by their soft bodies, which are often protected by a hard shell. Mollusks encompass a wide variety of organisms, including not just cephalopods like octopuses and squids, but also gastropods (like snails and slugs) and bivalves (like clams and oysters).

Cephalopods, which include octopuses and squids, are particularly notable for their advanced nervous systems, complex behaviors, and the ability to change color and texture, which helps them in communication and camouflage. This unique group is distinguished within the larger mollusk category due to their body structure, which typically includes a head with a set of arms or tentacles, a mantle covering their body, and a foot that is modified into siphons for locomotion.

The other classifications listed do not include octopuses and squids. Crustaceans are a separate group that primarily comprises animals like crabs and shrimp, worms are part of a completely different phylum, and insects represent a vast group of arthropods that do not fall under the mollusk classification. Thus, Mollusks is the accurate classification for oct
