Shark Brain

The nervous system of a fish differs only slightly from any vertebrate, due to its adaptation to its underwater habitat. The nervous system of a fish, and all other vertebrates, consists of two systems: the cerebrospinal system and the autonomic system. Within these systems fall the senses of touch, smell, sound, sight and taste. These 5 senses, in addition to a sixth sense for sensing voltage in their habitat, aid the fish in acquiring information from it's environment. This information is necessary for a fish to perform fundamental tasks for survival, such as food consumption and habitat distinction. Without the adapted nervous system that the fish possesses, survival in an underwater habitat would not be possible.
