The Octopus: An Alien Among Us
‘The octopus has a central brain and also an independent, smaller processor in each arm, giving it a unique mixture of centralized and distributed command. The octopus also probably has self models—rich, constantly updated bundles of information to monitor its body and behavior. From an engineering perspective, it would need self models to function effectively. For example, it might have some form of a body schema that keeps track of the shape and structure of its body in order to coordinate movement. (Perhaps each arm has its own arm schema.) In that sense, you could say that an octopus knows about itself. It possesses information about itself and about the outside world, and that information results in complex behavior.
