The sloshing water was reflected in the pool, building into waves-also known as a sieche-over a foot tall, Abby Wines writes in a statement for Death Valley National Park. But the shaking also rippled across the continent, setting off waves in Devil’s Hole, an 18-foot-long pool that branches deep into the Nevada aquifer.

The pupfish has also been threatened by introduced predators and competitors such as mosquito fish, crayfish, bullfrogs, and snails. As a result, the fish's water habitat has become polluted or has been drained. The desert pupfish population has declined because human populations have increased in its range, turning desert areas into communities. Efforts are underway to reintroduce the desert pupfish to various areas in Arizona. All natural populations of the fish were deemed extinct in Arizona in 1996. In Mexico, natural populations survive in four locations. Only three natural populations remain in California. The desert pupfish was once common in the Sonoran and Mojave Deserts of southern California, southern Arizona, and northwestern Mexico. Biologists (people who study living organisms) have no estimates of the desert pupfish's total population. The fish inhabits only scattered areas in southern California and northwestern Mexico.

It can tolerate very warm and very salty waters. The desert pupfish inhabits the shallow waters of desert pools, marshes, streams, and springs below 5,000 feet (1,524 meters) in elevation. Many die when intense summer heat dries up their streams and pools. The average life span of a desert pupfish is six to nine months, although some survive more than one year. Spawning continues throughout the summer. The males protect the eggs until they hatch three days later. After having mated, females begin spawning (laying eggs) at the end of February. Breeding males turn iridescent blue in color and fight each other over the right to mate with receptive females. When the weather and the water warms, the fish is active again and begins to mate. It becomes dormant during cold winter months, burrowing in mud at the bottom of its water habitat. The desert pupfish feeds primarily on brown and green algae. This pupfish has a short, scaled head with an upturned mouth. It is mainly silver in color with six to nine dark bands on its sides. The desert pupfish is small, ranging in size from 0.8 inch (2 centimeters) to 3 inches (7.6 centimeters) long. The desert pupfish is one of at least 35 species and sub-species of pupfish.
