Octopuses are not much like humans—they are invertebrates with eight arms, and more closely related to clams and snails. Still, they have evolved complex nervous systems with as many neurons as in the brains of dogs, and are capable of a wide array of complicated behaviors. In the eyes of Melina Hale, Ph.D., and other researchers in the field, this means they provide a great opportunity to explore how alternative nervous system structures can serve the same basic functions of limb sensation and movement.
