finned octopod

The finned octopod, also known as the finned octopod, is a type of octopus belonging to the order Octopoda, which is part of the subclass Coleoidea within the class Cephalopoda. These cephalopods are characterized by having eight arms and, in some species, one or two pairs of paddle-shaped fins at various life stages.12

Cephalopods are mollusks where the foot has evolved into arms and tentacles surrounding the head. They possess a highly developed central nervous system, forming a true brain encased in a cartilaginous cranium. While most modern cephalopods have internal or reduced shells, or lack them entirely, the finned octopod's classification is based on its soft-part anatomy, including the presence of fins. These creatures inhabit various marine environments, with some deep-sea species specifically noted for their fins.134
