Coelacanth

The coelacanth is a rare, ancient fish thought to have gone extinct around 66 million years ago, until it was rediscovered off the coast of Africa in 1938. It belongs to a group called lobe-finned fish, which have fleshy, limb-like fins that hint at the transition from aquatic to terrestrial animals. Coelacanths are deep-sea creatures, growing to about 6.5 feet long, and have unique physical features like a three-lobed tail and an unusual intracranial joint allowing head movement. They are considered living fossils, providing valuable insights into evolutionary history.
