The Coelacanth is unique in that it was discovered in the twentieth century despite how it was though to be extinct. In late 1938 a Coelacanth was caught at the Chalumna River on the eastern part of South Africa. The crew that caught it thought it looked unusual so it consulted a museum in the town of East London, South Africa for assistance with identifying it. It turned out that it was a fish that was identified as being the same as that of what fossilized remains of a Coelacanth featured.

 

The rediscovery of the fish prompted the change in the scientific name of the fish. The name was created in honor of East London Museum director Marjorie Courtney-Latimer and the South African ichthyologist Dr. J.L.B. Smith. Smith was informed by Courtney-Latimer of this discovery.

The grouping of the Coelacanth that was found was located in the Comoros Islands. This is a grouping of islands between the mainland and Madagascar. It was believed to be the only population of this fish in the world until the late part of the twentieth century.
