They were first found in 1938 when a fishing boat returning to the south African port landed an unusual catch unknown to the crew, the fish they landed was a coelacanth-a species thought to be extinct and only known through fossils! Coelacanths are so old they even predate the dinosaurs by several million years!
They are critically endangered with only a few hundred left in the world! one reason for this is because of the tidal currents. Another reason is because when they get caught, the resultant stress prevents them from returning to the deeper water and so they die in the warmer water.
