背的软条 (总数) : 8; 臀鳍软条: 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).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
营养阶层 (参考文献 69278):  2.0   ±0.2 se; based on size and trophs of closest relatives
回复力 (参考文献 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100). 🛈
