Enteroctopodidae

Enteroctopus is an octopus genus whose members are sometimes known as giant octopuses.

Enteroctopodidae is a small family of octopuses. This family was formerly considered a subfamily of the family Octopodidae sensu lato but this family has now been divided into a number of separate families with Enteroctopodidae as one of them.

Muusoctopus is a cosmopolitan genus of deep-sea octopus from the family Enteroctopodidae. These are small to medium-sized octopuses which lack an ink sac. Recent work has suggested that these octopuses originated in the North Atlantic and subsequently moved into the North Pacific while the species in the Southern Hemisphere are descended from multiple invasions from northern oceans.

Vulcanoctopus hydrothermalis, also known as the vent octopus, is a small benthic octopus endemic to hydrothermal vents. It is the only photographed species of the genus Vulcanoctopus. Other species such as Vulcanoctopus tangaroa and Vulcanoctopus tegginmathae have been accepted but are near undocumented. This vent octopus is endemic to the hydrothermal vent habitat that is located in the East Pacific Rise.
