The Tuberculate Pelagic Octopus (Ocythoe tuberculata), also known as the Football Octopus, is a pelagic species that is found in warm and temperate seas, especially in the northern hemisphere. It is the only known species in the family Ocythoidae.
The females are around a metre long when full-grown. The males are considerably smaller at around 10 cm.
As a species, they are unique among cephalopods in possessing a true gas bladder. They are also one of the only known ovoviviparous cephalopod species. It is relatively unresearched in terms of behaviour and life-cycle.
Young females and mature males have been observed residing inside salps, although little is known about this relationship.
