The first brain is located in the head of the octopus and controls sight, smell, hearing, touch and taste. This makes up most of an octopus’s brain mass. The second brain is called a “mid” or “meso” brain. It resides in the body and has three lobes. The mid brain is responsible for smell, touch, taste and maintains the octopus’s ...
