While your brain resides in your head, other animals, like snails, have brains that are spread throughout their bodies. Ganglias, or nerve cell clusters, are distributed through the body in small groups. In the octopus, however, most of their ganglias bunch together, creating a brain structure. Brain size does not always indicate how intelligent an animal is, but as a general rule, animals with larger brain-to-body ratios tend to have more “brain power” to invest.
