Coelacanth

Coelacanth are an ancient order of fish believed to have gone extinct at the end of the Cretaceous period some 65-plus million years ago. That was until 1938, when one was miraculously discovered off the east coast of South Africa near the mouth of the Chalumna River. Closely related to lungfishes and tetrapods, coelacanths are among the oldest living jawed fishes known to exist. They can live as long as 100 years and swim at depths of 90 to 100 meters.
