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).
Body shape (shape guide): elongated.

生物學特性     字彙 (例如 epibenthic)
