Proteroctopus is an extinct genus of

Vampyropoda, less closely related to octopus or vampire squid than either of the two groups are to each other.[2] A phylogenetic analysis by Kruta et. al indicates that Proteroctopus may be more closely related to the Vampyromorpha based on its unique morphology: two fins, head fused to the body, eight arms, two rows of oblique sucker, a gladius and absence of an ink sac.[2] A 2022 phylogenetic analysis also found it to be more closely related to vampire squid than to octopuses.[3]

The morphology of P. ribeti suggests a necto-epipelagic mode of life.[1]
