Definition
Coelacanth is any sarcopterygian fish of the subclass Coelacanthimorpha (Actinistia) and order Coelacanthiformes, characterized by a three-lobed, diphycercal caudal fin, external nostrils, and an anterior dorsal fin in front of the center of the body (Nelson 2004). While coelacanths are well recognized in the fossil record, there are only two living species, Latimeria chalumne and Latimeria menadoensis.
