Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 9 - 10. Body long, slender and compressed; dorsal-fin origin in front of pelvic-fin origin; upper lobe of caudal fin longer than lower lobe; barbel at corner of slightly subterminal mouth; scales on lateral line 57-64, usually 60-62; dorsal fin with 9-10 rays; 1st gill arch with 14-18 rakers; pharyngeal teeth 2,5-5,2; olive-gray above, silver gold side; large specimen with hump on nape; and red-orange caudal and paired fins (Ref. 86798).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [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): 2.9 ±0.3 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 (34 of 100).
