Any of various fishes of the order Coelacanthiformes, having lobed, fleshy fins. Coelacanths are crossopterygians, the ancient group of lobe-finned fishes that gave rise to land vertebrates. They were known only from Paleozoic and Mesozoic fossils until a living species (Latimeria chalumnae) was found in the Indian Ocean in 1938. At least one other (Malania anjouanae) has been discovered since then.
