Coelacanth

Edit

The coelacanth is a rare and ancient lineage of lobe-finned fish belonging to the class Actinistia. Once thought to have been extinct for over 65 million years, the rediscovery of the coelacanth in 1938 off the coast of South Africa challenged prevailing assumptions about the fossil record and the dynamics of extinction. This "living fossil" provides invaluable insights into vertebrate evolution, particularly the transition from aquatic to terrestrial life.
