Octopuses are famous for their eight limbs, but they have even more brains than arms: nine. The primary brain does all the decision-making, and one smaller brain is within each of the eight arms. enabling decentralized processing and autonomous functionality. With so many appendages, they need the extra processing power to sort out all the information coming in and allow the arms to perform tasks while the primary brain pays attention to to other stimuli. As if eight arms and nine brains weren’t enough, an octopus also has three hearts and blue blood.
