Nervous System
Surprisingly enough, a shark's brain is actually relatively large and complex. The ratio of body to brain in most sharks is similar to those in humans and other mammals. With this said, there is actually not much known about the brains of any sharks. Because of the complexity, large gaps remain till today in research as compared to other animals. This is mainly due to the fact that sharks are difficult to keep and study, with all kinds of complications when examining too.
From what is known, we can establish that sharks can learn tasks, remember things, and show a particularly complex social behavior. The respective brain areas that control these skills however, have little information and knowledge linked with them.
It proves that similar to humans, together with the spinal cord, which is protected by the spine, the brain forms the central nervous system. This is where the network of peripheral nerves transmitting information from and to the muscles and (sensory) organs meets.
