The Julimes pupfish (''Cyprinodon julimes'') ((スペイン語:Cachorrito de Julimes)), is a killifish belonging to the family Cyprinodontidae (pupfish) of ray-finned fish, endemic to "El Pandeño" hot spring in Julimes, Chihuahua, Mexico. The pupfish is known as the "hottest fish in the world"〔Fleming, D. 2012. Mexico Day 5: An encounter with the world’s hottest fish. WWF-UK. http://blogs.wwf.org.uk/blog/climate-energy/mexico-day-5-an-encounter-with-the-worlds-hottest-fish/〕 due to its adaptation to life in a hot spring that reaches temperatures as high as . The species was taxonomically described in 2009 as similar to ''Cyprinodon eximius'', but it has a bigger head, nearly one-third of its Standard Length. Its body is deep, the dorsal and ventral profile is convex and the lower jaw exceeds the premaxilla. The dorsal fin is placed forward with respect to the pelvic fin.〔De la Maza-Benignos, M. and L. Vela-Valladares. 2009. “Cyprinodon julimes sp. nov”. Los Peces del Río Conchos (editor: De la Maza-Benignos, M.). Alianza WWF - FGRA y Gobierno del Estado de Chihuahua. 〕 Females and young have reticulate patterns of dark and light silver-brownish bands of varying lengths and thickness over the flanks, as well as a conspicuous black spot or ocellus on the distal edge of the dorsal fin. Dominant males are bluish-green in color and show a black bar along the distal edge of the caudal fin.〔 Holotype.- UANL 18721 Collected by Ma.de Lourdes Lozano Vilano, Mauricio De la Maza Benignos, Ma.

The system is located within the Middle Rio Conchos Basin and consists of a geothermal spring and a series of divergent canals. Until year 2011 ''C. julimes'' was restricted to an area of approximately that is part of the original system and a contiguous man-made blind canal, with depth ranging from and constant water temperatures ranging between .〔〔De la Maza-Benignos M., J.A.
