簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 8; 臀鰭軟條: 8. Previously thought to be of hybrid origin and similar to parental Gila robusta and G. intermedia. Dorsal and anal fins with 8 rays; lateral line with 71-90 scales, usually fewer than 80; first gill arch with 10 or more rakers; and often with diffuse stripes on dark gray or brown side, dark fin membranes (Ref. 86798).
Inhabits pools and undercut banks of headwaters, creeks and small rivers. Maximum length is presumably about 38 cm TL (Ref. 86798).
