INTRODUCTION
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.
