A female can lay up to 500 eggs; clusters of eggs are joined by special stalks. The female then sits with her eggs until they are ready to hatch. If any creature comes near the eggs, the female will attack it, though if it kills the creature, will not eat it. The eggs take 50 to 80 days to hatch, but will hatch more quickly in warmer waters.
The eggs of Pinnoctopus cordifomis are of intermediate size (6.43 ± 0.21 mm L; 1.45 ± 0.11 mm W; 6.41 ± 0.52 mg TW) the yolk can be seen through the wall of the egg and represents approximately 57% of the eggs size, they are pear-shaped. Once the eggs are hatched paralarvae are released which survive without intervention for the duration of ...
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 ...
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. Here she guards and cares for them for about five months (160 days) until they hatch. [70]
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.
Macroctopus maorum is a large octopus and it is regularly described as a ‘robust’ species, it is a member of the Octopus macropus species complex. The morphological traits characteristic of this complex are a high number of gill lamellae, a robust conical copulatory organ and arms of varying length with long unequal dorsal arms generally four to six times longer than the mantle.
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 ...
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. [ 3 ] [ 4 ] 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.
