The Devil’s Hole pupfish is the smallest of the known pupfish. They reside only in the state of Nevada, in the United States. They also only live in up to the first 80 feet of water and have a territory of between 3 – 5 feet across. Devil’s Hole is a naturally occurring body of water formed in a small cavern in the earth.

They face the threats of agricultural water use, flash floods, earthquakes, and vandalism to their habitat. Their population is also decreasing.
