Etymology: Empetrichthys: Greek, empetros = growing in rocks (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生態學
; 淡水 居於水底的; pH range: 7.8 - 8.4; dH range: 7 - 30; 非遷移的. 熱帶; 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.
北美洲: 侷限於在 Pahrump 山谷的三個泉水了, 在美國內華達州的 Nye 縣在那裡它是唯一的原生魚。 現在只有在 Pahrump 山谷以外存在, 在那裡它被移植避免它的滅絕。
