Etymology: Empetrichthys: Greek, empetros = growing in rocks (Ref. 45335).
Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
; eau douce démersal; pH range: 7.8 - 8.4; dH range: 7 - 30. Temperate; 20°C - 25°C (Ref. 12468); 37°N - 36°N
North America: restricted to three springs in Pahrump Valley, Nye County in Nevada, USA where it was the only native fish. Now exists only outside Pahrump Valley, where it was transplanted to prevent its extinction. Three subspecies were recognized: Empetrichthys latos latos, the only surviving subspecies; Empetrichthys latos pahrump; and Empetrichthys latos concavus.
