Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 14 - 22; Anal soft rays: 20 - 24; Vertebrae: 28 - 29. This species is distinguished from its congeners by the following set of characters: presence of distal black strip in dorsal fin of adult males; scales on peduncle series 15-16; dorsal-fin origin on transversal plane through bases of 3rd-4th anal-fin rays in males; neuromasts on ventral opercular series 3; dark filaments in dorsal and anal fins 1; neuromasts on infraorbital series 16-17; light orange flank color; neuromasts on preopercular series 12-13; length dorsal-fin base 19.3-36.0%; ventral opercular neuromasts series 1; and by caudal-fin length 21.6-26.8% (Ref. 138871).
Body shape (shape guide): fusiform / normal.

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.2   ±0.4 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.).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (10 of 100). 🛈
