Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 72 - 74; Anal spines: 0; Anal soft rays: 58 - 59. Body brownish, a small dark blotch at junction of straight and curved parts of lateral line. Body deep ovoid, its depth 1.8 to 2 times in SL. Head length 3.1 to 3.3 times in SL. Upper-eye diameter 5.3 to 5.9 times in head length. Maxilla extending to below posterior margin of lower eye. Upper-jaw length 2.3 to 2.4 times in head length. Teeth in upper jaw small and close-set laterally, and enlarged anteriorly. Teeth in lower jaw stronger and more widely spaced than those of upper jaw. Pectoral fin on ocular side with 12-13 soft rays (Ref 9774).

Biology     Glossary (e.g. epibenthic)

Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 29.1, mean 28 °C (based on 98 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00343 - 0.01604), 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):  3.4   ±0.42 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
Price category (Ref. 80766):   Very high.
