What is a "coelacanth"?

A coelacanth is a prehistoric fish often referred to as a "living fossil" due to its ancient lineage and resemblance to its ancestors from millions of years ago. This elusive fish was thought to have gone extinct until its rediscovery in the 20th century, making it one of the most remarkable zoological discoveries. Coelacanths have unique features such as lobed fins, a hinged skull, and a primitive lung-like structure. They inhabit deep-sea environments and are known for their slow-moving and secretive behavior. Coelacanths are believed to play an important role in understanding the evolution of vertebrates, providing valuable insights into the early stages of aquatic life. Due to their rarity and conservation status, studying coelacanths remains a challenge, but their existence serves as a testament to the resilience and continuity of life on Earth.
