Octopuses have also been observed in what has been described as play: repeatedly releasing bottles or toys into a circular current in their aquariums and then catching them. [ 32 ] Cephalopods can demonstrably benefit from environmental enrichment [ 33 ] indicating behavioral and neuronal plasticity not exhibited by many other invertebrates.
However, they don’t have just one brain, but a central brain in their head and a mini-brain in each arm. Like humans and other mammals, octopuses are adaptable and great problem-solvers. Watch ...
Octopuses (along with cuttlefish) have the highest brain-to-body mass ratios of all invertebrates; [48] this is greater than that of many vertebrates. [49] Octopuses have the same jumping genes that are active in the human brain, implying an evolutionary convergence at molecular level. [ 50 ]
[12]: 2 These chromatophores are found throughout the body of the octopus, however, they are controlled by the same part of the brain that controls elongation during jet propulsion to reduce drag. As such, jetting octopuses can turn pale because the brain is unable to achieve both controlling elongation and controlling the chromatophores. [ 40 ]
The common octopus (Octopus vulgaris) is a mollusk belonging to the class Cephalopoda. Octopus vulgaris is one of the most studied of all octopus species, and also one of the most intelligent. It ranges from the eastern Atlantic, extends from the Mediterranean Sea and the southern coast of England , to the southern coast of South Africa.
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.
The brain, optic lobes, and the highly developed arm nervous system are the three main components of the octopus nervous system. [15] Each arm of the octopus has been described as having its own brain, where individual processing, motor systems, and sensory exploration can occur. This is where the concept that octopus have many brains comes ...
