prehistoric fish
Primordial aquatic creature
Prehistoric fish are fish species that existed in ancient geological periods, known primarily through fossils.
The term covers everything from the jawless fish of the Cambrian period to armored placoderms and early sharks.
In casual use, prehistoric fish may describe any ancient-looking or "primitive" species: The coelacanth looks like a prehistoric fish—because it basically is one.
