This also makes it the longest-living octopus – most octopuses only live for 1 or 2 years – which this octopus beats with its brooding period alone. [ 4 ] [ 5 ] Female Graneledone boreopacifica tend to brood their eggs between the depths of 1,200 and 2,000 metres (3,900 and 6,600 ft); the eggs were never unattended.
One deep-sea octopus species broods its eggs for four and a half years. Away from the hydrothermal vents in the near-freezing temperatures of the deep sea, egg-brooding periods are thought to last ...
Octopus aquaculture is the captive raising of octopuses and commercial ... Octopuses live short ... and a high fecundity of 100,000–500,000 eggs per female. ...
Marine scientists discovered what they dubbed an 'octopus garden' nearly two miles below sea level. 'We were just absolutely floored.' Just off California, octopuses are converging by the thousands.
Female giant Pacific octopus guarding strings of eggs. About forty days after mating, the female giant Pacific octopus attaches strings of small fertilised eggs (10,000 to 70,000 in total) to rocks in a crevice or under an overhang.

Researchers have documented an active octopus nursery, where hundreds of the deep-sea creatures cluster together to brood their eggs. Rare octopus discovery made 2 miles below the ocean surface ...
Female cephalopods lay eggs in clutches; each egg is composed of a protective coat to ensure the safety of the developing embryo when released into the water column. Reproductive strategies differ between cephalopod species. In the giant Pacific octopus, large eggs are laid in a den; it will often take several days to lay all of them. [112]
