Muusoctopus
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.
These octopus species are known to spawn a single batch of eggs instead of producing batches of them over time. As much as these octopuses may release eggs simultaneously or in batches in an extremely short period, they are mostly not prolific spawners.
