Like cockroaches and squid, the octopus’ neurology is controlled by multiple separate brains — nine in the case of this strange octopod. And plenty of their skills of manipulation come down to the fact that they can use those brains to control eight distinct tentacles. But their circulatory system is just as unusual.
Why does an octopus have 9 brains?
Octopuses have 3 hearts, because two pump blood to the gills and a larger heart circulates blood to the rest of the body. Octopuses have 9 brains because, in addition to the central brain, each of 8 arms has a mini-brain that allows it to act independently.
