Cthulhu is said to resemble a green octopus, dragon, and a human caricature, hundreds of meters tall, with webbed, human-looking arms and legs and a pair of rudimentary wings on its back. [11] Its head is depicted as similar to the entirety of a gigantic octopus , with an unknown number of tentacles surrounding its supposed mouth.
Strategies to defend themselves against predators include the expulsion of ink, the use of camouflage and threat displays, the ability to jet quickly through the water and hide, and even deceit. All octopuses are venomous , but only the blue-ringed octopuses are known to be deadly to humans.
The octopuses seen in the videos threw silt, shells, and algae at other nearby octopuses. To do so, they gathered up the debris underneath their bodies using their arms.
[10] Octopus eyes, too, look and work much like those of vertebrates; but there, Baer remarks, the similarities end. Cephalopods are "immensely foreign", with "a distributed sense of self" and a "lived reality" quite unlike human consciousness, a feature that, he notes, Godfrey-Smith calls "the most difficult aspect of octopus experience to ...
In communal defence, prey groups actively defend themselves by grouping together, and sometimes by attacking or mobbing a predator, rather than allowing themselves to be passive victims of predation. Mobbing is the harassing of a predator by many prey animals. Mobbing is usually done to protect the young in social colonies.
Akkorokamui (Japanese: アッコロカムイ, Ainu: At-kor-kamuy) is a gigantic octopus-like monster from Ainu folklore, similar to the Nordic Kraken, which supposedly lurks in Uchiura Bay in Hokkaido. [1] It is said that its enormous body can reach sizes of up to 120 metres (390 feet) in length. [2] Its name can be translated as "tentacle ...
To understand the inner details of octopus lives, researchers dived for about a month at a reef off the coast of Eilat, Israel, and tracked 13 octopuses for a total of 120 hours using several cameras.
Octopuses can maintain a constant oxygen uptake even when oxygen concentrations in the water decrease to around 3.5 kPa (0.51 psi) [22] or 31.6% saturation (standard deviation 8.3%). [17] If oxygen saturation in sea water drops to about 1–10% it can be fatal for Octopus vulgaris depending on the weight of the animal and the water temperature ...
