Squid
The squid's nervous system is highly developed. It has one brain that consists of two fused nerve centers that are linked down the body by two massive nerve axons. These nerve axons are made up of bundles of fused nerve fibers that transmit data very quickly. Squids have two eyes which can each focus separately. This is because information from each eye travel through a big optic nerve to it's brain.
