Bathypolypus sponsalis, commonly called the globose octopus, is a deep sea cephalopod that can be found in both the eastern Atlantic Ocean and the Mediterranean Sea. It possesses many morphological traits adapted to a deep sea environment, including large eggs, reduced gills , no ink sac , and subgelatinous tissues.
Climate change adaptation is the process of adjusting to the effects of climate change. These can be both current or expected impacts. [1] Adaptation aims to moderate or avoid harm for people, and is usually done alongside climate change mitigation. It also aims to exploit opportunities. Humans may also intervene to help adjust for natural ...
Vulcanoctopus hydrothermalis, also known as the vent octopus, is a small benthic octopus endemic to hydrothermal vents. [1] It is the only known species of the genus Vulcanoctopus . This vent octopus is endemic to the hydrothermal vent habitat that is located in the East Pacific Rise.
Climatic adaptations limits to adaptations that have been established, characterizing species that live within the specific climate. It is different from climate change adaptations which refers to the ability to adapt to gradual changes of a climate. Once a climate has changed, the climate change adaptation that led to the survival of the ...
Shifts in available prey may force a change in octopus diets to other, nonshelled organisms. [citation needed] Because octopuses have hemocyanin as copper-based blood, a small change in pH can reduce oxygen-carrying capacity. A pH change from 8.0 to 7.7 or 7.5 will have life-or-death effects on cephalopods. [23]
O. briareus is not a social animal, and stays at a safe distance from other octopuses of the same species, except for mating. If faced with a predator, a Caribbean reef octopus, like most other octopuses, sucks up a volume of water then expels it quickly in the form of a jet to propel itself away. To further deter predators, it can eject ink to ...
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.
Bathypolypus arcticus is a small, short-armed octopus which is between 6 and 10 cm (2.4–3.9 in) in length, [4] with an average adult weight of around 45 g (1.6 oz) [2] and a maximum of 300 g (11 oz). [3] Like other deep-sea octopuses, Bathypolypus arcticus do not have ink sacs. [2] The mantle is globular, being nearly as wide as it is long.
