Morphology | Morphometrics
soft rays: 7 - 8. Moapa coriacea is distinguished by its leatherlike skin resulting from having many small embedded scales, large black spot on caudal-fin base, fairly slender body, dorsal fin origin over or slightly behind pelvic origin, long rounded snout, slightly subterminal mouth, complete or incomplete lateral line with 69-79 scales, 8 anal rays (often 7), pharyngeal teeth 0,5-4,0. Color consists of olive above, broad dusky stripe along back, cream spot at dorsal fin origin, green-brown blotches along upper side, turquoise stripe above dark gold-brown stripe alongside (faint at front) Ref. 86798).
Inhabits pools of Moapa River and feeder springs over gravel, sand and mud (Ref. 86798).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00445 - 0.02830), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.5 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
