alt Hacker NewsI found the article very interesting. Not click bait at all.
I didn't realize that an octopuses brain was spread out all over its body.

It's like 9 brains, one central one in the head and 8 semi-autonomous ones in the arms. Makes one wonder what an octopus consciousness is like. Is it distributed among the nine brains, or focused on the central one? If the latter then the arm-brains would be zombie minds. It's also possible the 8 arms have their own separate experiences.
We also have a nervous system distributed throughout our bodies, so we do experience the full body, but the neural signals are sent to one location, not nine. We experience ourselves as a unified hole, allowing exceptions for certain conditions.

Not only that, they have the highest ratio of brain-to-body-mass of any invertebrate.
