Angayukaksurak char
The angayukaksurak char is a type of salmonid fish found in Alaska in a few select Brooks Range headwaters.
It was described as a distinct species on morphological grounds by Morrow in 1973, but the concept of a separate species status was soon refuted, even by Morrow himself. Further genetic studies have also failed to distinguish this fish from the more widespread Dolly Varden trout, and it is now considered to represent natural variation within that subspecies.
