North America: Amargosa River basin in Nevada and California, USA. Six subspecies were recognized: Cyprinodon nevadensis nevadensis, restricted to Saratoga Springs and adjoining lakes, Death Valley National Monument in California; Cyprinodon nevadensis amargosae, restricted to Amargosa River in California; Cyprinodon nevadensis calidae, now extinct, in outlets of North and South Tecopa Hot Springs in California; Cyprinodon nevadensis shoshone , in outlet of Shoshone Springs in California; Cyprinodon nevadensis mionectes, in large springs in lower Ash Meadows in Nevada; Cyprinodon nevadensis pectoralis, in small springs in hills around Devils Hole, upper Ash Meadows in Nevada.

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 7.8 cm TL male/unsexed; (Ref. 86798); common length : 4.5 cm TL male/unsexed; (Ref. 12193)

Occurs in springs, their effluents, and spring-fed ponds and lakes (Ref. 5723, 86798). Not a seasonal killifish. Is difficult to maintain in aquarium (Ref. 27139).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Its reproductive strategies differ from many spring-dwelling pupfishes. Cyprinodon n. amargosae is a group spawner. Males do not establish and defend territories as do males of spring-dwelling subspecies. Instead, a reproductive male usually directs a receptive female to the periphery of the group where spawning occurs, although spawning may even take place in the center of the group (www.death-valley.us).
