Lobefin
Lobefins are a group of fish characterized by their fleshy, lobed fins, which are more robust than the fins of typical bony fish. This unique fin structure allows them to maneuver in shallow waters and potentially move onto land, making them significant in the study of vertebrate evolution. Lobefins include species like coelacanths and lungfish, which are considered close relatives to the ancestors of terrestrial vertebrates.
These fish are primarily found in freshwater and marine environments. Lungfish are known for their ability to breathe air, while coelacanths were once thought to be extinct until a living specimen was discovered in 1938. Both groups provide valuable insights into the transition from aquatic to terrestrial life.
