Short description
Identification keys | Morphology | Morphometrics
This species is distinguished by the following characters: coloration - a vertically elongated humeral spot, a vermilion longitudinal band which runs from operculum along the body up to the dorsal part of the caudal peduncle and to the rays of caudal fin, an elongated caudal spot which is asymmetrically on the lower part of the caudal peduncle and the basis of caudal fin sometimes up to the tips of the fin rays; pored lateral line scales 10-15, relatively long; scales in longitudinal row 34-36; scales transversal before dorsal fin 6/1/3½ to 4; A iii- iv, 19-21; maxillary teeth 1-4; (x=2,32); body depth 2,91 (2,70-3,26) times in standard length; head length 3,99 (3,58 to 4,61) times in standard length; dorsal fin begins before midbody (Ref. 101436).

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=0.01202 (0.00496 - 0.02912), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±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).
