Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 84 - 93; Anal spines: 0; Anal soft rays: 62 - 73; Vertebrae: 34 - 36. 11-12 pectoral fin rays on ocular side, 10 on blind side. Preserved specimens uniformly brownish on ocular side, yellowish-white on blind side; fins paler than body (dorsal and anal fins with regular series of dark blotches); pectoral fin on ocular side with dark bars; caudal fin with scattered indistinct dark blotches (Ref. 10878). Exhibits sexual dimorphism, mature males with greater interorbital width compared to females and the upper one or two pectoral fin rays on the ocular side are extended and filamentous (Ref. 10878).

Estimates based on models

Preferred temperature (Ref. 123201): 18.3 - 20.9, mean 19.3 °C (based on 19 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00396 - 0.01388), b=3.07 (2.91 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±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 (20 of 100).
Price category (Ref. 80766):   Very high.
