Animal Profile

Animal Name: Tecopa Pupfish
Scientific Name: Cyprinodon nevadensis calidae

Physical Description:
A small, silvery fish with iridescent blue-green hues, rounded fins, and a stocky body adapted to high temperatures. Males displayed brighter coloration during breeding. Adults measured only about 3.5 cm long. It was known for its ability to survive in thermal spring outflows with temperatures exceeding 40°C.

Habitat:
Endemic to Tecopa Hot Springs, Mojave Desert, California, USA. Lived in the outflows of two geothermal springs, relying on the unique chemistry and temperature of the water. Its range was extremely limited—just a few square meters of habitat.

Existence Status / Date:
Extinct (officially declared in 1981)
Last observed in 1970, extinction driven by:
– Habitat modification for tourism (bathhouses and pools)
– Introduction of non-native species (e.g., Mosquitofish)
– Water diversion and pollution

Content Summary:
The Tecopa Pupfish (Cyprinodon nevadensis calidae) was one of the first U.S. species to be declared extinct under the Endangered Species Act. Its story is a cautionary tale of how even well-intentioned development can erase an entire species when ecological nuance is ignored.
