Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 8; Anal soft rays: 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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
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).
Trophic level (Ref.
69278): 2.0 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (28 of 100).
