Adaptations for aquatic life

term ocean survival is that of the coelacanth. Fossils of this armored fish dating back more than 75 million years have been discovered, and it was thought to have been extinct. In 1938, however, one was caught off the coast of South Africa. Since then, more than 100 of these prehistoric, deep-dwelling fish have been examined. They have no scales or eyelids, as do "modern" fish, and have quietly kept to themselves in the deepest areas of the ocean.
