The centralized brain, which is connected to the eyes, can help the animal perceive the world around it, evading predators and seeking out a juicy crab hiding under a rock. But because an octopus’s neurons are spread into its arms, each arm can think and make basic decisions for itself. Squid does indeed have three brains, each one responsible for different functions. The first brain controls the squid’s body movement, while the second brain controls its eyesight. And lastly, the third brain controls what the squid eats. Each of these three brains has about 2 million neurons connected together. Within the clade of mollusks, cephalopods have developed an unusually large and complex nervous system. The increased complexity of the cephalopod centralized “brain” parallels an amazing amount of complex behaviors that culminate in one order, the octopods. The mechanisms that enable evolution …The researchers identified the same active transposon, or ‘jumping gene’, in human brains and in two species of octopus, the common Octopus vulgaris and the Californian Octopus bimaculoides. …They have nine brains – one mini-brain in each arm and another in the center of their bodies.
