Poecilia thermalis and its natural habitat.
A.-F. Representative specimens of Poecilia thermalis (males on top, females below). A. & B. represent artistic depictions of the species from the original description by Steindachner [35]. C.-F. are photos of freshly collected specimens of the P. thermalis from the large La Esperanza spring in 2012. G. The type locality of P. thermalis at La Esperanza (large spring), Chiapas, Mexico, a typical sulfidic spring habitat. H. A second, smaller sulfide spring (La Esperanza small spring) in close proximity to the type locality, which is also inhabited by P. thermalis.
