Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 67 - 76; Anal spines: 0; Anal soft rays: 51 - 56. Body brownish, a distinct, large dark blotch at junction of straight and curved parts of lateral line and a smaller blotch on middle of straight section of lateral line, many dark rings scattered on body. Upper profile of head without notch in front of eye. Scales on eyed side ctenoid on anterior part and dorsal and ventral margins of body on eyed side, cycloid on remaining areas. Pectoral fin on ocular side with 11-12 soft rays (Ref 9774).

Estimates based on models

Preferred temperature (Ref. 123201): 23.8 - 28.8, mean 28 °C (based on 226 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.17 (3.00 - 3.34), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
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.
