soft rays: 8. Brown with irregular spots; dorsal and caudal fins with bands in females, dusky in males; often with dark brown saddle below each of the dorsal fins (Ref. 2798); characterized further by having upper five pectoral rays with free tips and sixth ray partly free; three branches on upper four pectoral rays; rounded caudal fin; longitudinal scale series 37-38; predorsal scales 18-20, reaching or nearly reaching interorbital space; cheek and opercle without scales; presence of fleshy double flap from edge of cheek into notch at posterior end of upper lip; ctenoid body scales, becoming cycloid on abdomen, breast, base of pectoral fin and nape; depressed head, width greater than depth; depth of body 4.3-5.5 in SL (Ref. 90102).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.2 - 29.3, mean 28.2 °C (based on 3609 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 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.).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
