Nevada Devil's Sinkhole is a Unique Ecosystem to the Devil's Hole Pupfish

The Devil's Hole Sinkhole in Nevada is a unique ecosystem that houses an endangered species unique to it.  This species is called the Devil's Sinkhole Pupfish (Cyprinodon diabolis).  This amazing fish was first discovered in 1890, but recognized as a unique species in 1930.  The Sinkhole itself was made part of the Death Valley National Monument in 1952.  This sinkhole is about 45 feet deep, about 60 feet long, and about 9 feet wide.

The Devil's Hole Pupfish are bright blue in color, and about 1 inch long.  They were listed as endangered in 1967.  Its population fluctuates between 150 and 500 fish during the year.  To further preserve this species, artificial habitats have been created, and the some of the fish are being stablished there.  One of the things that make this species unique is how they have adapted to the conditions of this sinkhole.  One of these adaptations is to the constant but high temperature of 93°F.  They live most of their lives in a depth range of depth that is only about 1 foot deep.
