coelacanth (plural coelacanths)

1. Any of the class Actinistia of primitive lobe-finned fish, thought to have been extinct for 70 million years until a living specimen was discovered in 1938. Most species are large and plump and they all have bodies covered in tough elasmoid scales that act as armor.
