cephalopods

Squid and octopus

Cephalopods are marine mollusks with tentacles attached to their heads—octopuses, squid, cuttlefish, and nautiluses.

The name means "head-foot," describing their distinctive anatomy.

They're known for intelligence, camouflage abilities, and jet propulsion.

Unlike their shelled mollusk relatives, most cephalopods have reduced or lost their shells entirely.
