The spoon-armed octopus (Bathypolypus arcticus) can live 1,000 m (3,300 ft) deep, and Vulcanoctopus hydrothermalis lives in depths of 2,000 m (6,600 ft) around hydrothermal vents. [28] Some species, such as Megaleledone setebos and Pareledone charcoti , can surive in the chilling waters of the Antarctic, which reach −1.8 °C (29 °F). [ 44 ]
Eggs are fertilized upon exiting the oviducts. Female octopuses generally lay their eggs in shallow water and stays with the egg mass in order to protect it. [14] In the species A. aculeatus which is closely related to A. capricornicus, female octopuses rarely reject the mating advances of the male octopus. It was also seen that males of this ...
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.
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.
East Pacific red octopus, rescued from a gull near Los Osos, California. Octopus rubescens (commonly the East Pacific red octopus which is a Cephalopod, and also known as the ruby octopus, a preferred common name due to the abundance of octopus species colloquially known as red octopus [1]) is the most commonly occurring shallow-water octopus on much of the North American West Coast and a ...
Many species are found in the twilight zone, while others live closer to shore in warmer waters. However, some species, like the dumbo octopus, live in the midnight zone where sunlight never reaches.
Now researchers may have solved the mystery of why these pearl octopus congregate: Heat seeping up from the base of an extinct underwater volcano helps their eggs hatch faster.
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.
