soft rays: 7 - 9;
Vertebrae: 26. Body with distinct dark oblique shoulder bar, scale margins rimmed with narrow dark line forming reticulate pattern usually overlaid by narrow dark bars and dorsal saddles; 2 dark spot at caudal base (Ref. 43716). Longitudinal scales 29-33; TRB 9-12; predorsal scales 12-19, small, reaching to above preopercular margin; scales on body mostly ctenoid; first dorsal spine white and always longest, often filamentous (Ref. 43716).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00444 - 0.02358), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.3 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 (12 of 100) .
