The Tecopa pupfish (Cyprinodon nevadensis calidae) is an extinct subspecies of the Amargosa pupfish (Cyprinodon nevadensis). The small, heat-tolerant pupfish was endemic to the outflows of a pair of hot springs in the Mojave Desert of Inyo County, California. Habitat modifications, the introduction of non-native species and hybridization with the related Amargosa River pupfish led to its extinction around 1979.
