The 200 or so species of octopuses are mollusks belonging to the order Cephalopoda, Greek for ‘head-feet’. Those heads contain impressively large brains, with a brain to body ratio similar to that of other intelligent animals, and a complex nervous system with about as many neurons as that of a dog.
