This increased distinguishable shape of the optic lobe is likely due to the change from planktonic to benthic life as they grow and develop. [12] Where many other currently studied octopus species have only five gyri, the A. capricornicus has seven which suggests that these organisms are more behaviorally complex. [11]
Due to their intelligence, octopuses are listed in some countries as experimental animals on which surgery may not be performed without anesthesia, a protection usually extended only to vertebrates. In the UK from 1993 to 2012, the common octopus ( Octopus vulgaris ) was the only invertebrate protected under the Animals (Scientific Procedures ...
Blue-ringed octopuses spend most of their time hiding in crevices while displaying effective camouflage patterns with their dermal chromatophore cells. Like all octopuses, they can change shape easily, which allows them to squeeze into crevices much smaller than themselves.
About one-third of the throws happened when the octopuses were cleaning out their dens, and these tended to be objects such as shells, which were launched into the water without any apparent target.
Octopuses do not regulate their internal temperatures until it reaches a threshold where they must begin to regulate to prevent death. [19] The increase in metabolic rate shown with increasing temperatures is likely due to the octopus swimming to shallower or deeper depths to stay within its preferential temperature zone.
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.
Secrets of the Octopus explores the life, culture, and behavior of different octopus species across the globe. Featuring narration by actor Paul Rudd, and commentary and discussion by a number of marine biologists, scientists, and experts in the field, the documentary series seeks to bring viewers closer than ever to one of the planet's most elusive and alien creatures.
The octopus is one of the most unexplainable animals on the planet, contested only by the platypus, the echidna, and the angler fish. And trust us, you don't know squat about what it can do.View ...
