The Death Valley Pupfish (Cyprinodon salinus) is a species of fish that is the last known survivor of what is thought to have been a large ecosystem of fish species that lived in Lake Manly which dried up at the end of the last ice age leaving the present day Death Valley in California. The pupfish is adapted to the shallow, hot, salty water of a particular part of Salt Creek that flows above ground year-round. Another sub-species lives in nearby Cottonwood Marsh.
