Complex brains have only evolved in vertebrates, with the exception being soft body cephalopods, for example, octopuses. Research has shown that octopuses share a common gene with humans, a gene ...
Unlike in many other animals, including other mollusks, the complex motor skills of octopuses and their relatives are not organised in their brains via internal somatotopic maps of their bodies [60] Octopuses have the same jumping genes that are active in the human brain, implying an evolutionary convergence at molecular level.
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.
All octopuses [25] and most cephalopods [26] [27] are considered to be color blind. Coleoid cephalopods (octopus, squid, cuttlefish) have a single photoreceptor type and lack the ability to determine color by comparing detected photon intensity across multiple spectral channels.
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 ...

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.
