Octopuses exhibit remarkable intelligence and adaptability, possessing about 500 million neurons, similar to dogs, with most situated in their arms. This decentralized nervous system allows each arm to process sensory input and initiate movements independently, described as having 'mini-brains.' This unique capability aids octopuses in adapting to challenges such as injury. Research into unique cases, such as an Octopus vulgaris with nine arms, offers insights into their neural adaptability and evolutionary progress over time.
In essence, the arms have their own 'mini-brains.'
