Morphology | Morphometrics
soft rays: 20. Short supraorbital tentacle; first dorsal-fin 25% shorter than second dorsal fin; male coloration whitish with fine specks of black dots, darkening on area of opercle; rough reticular pattern of deep reddish brown on body; base of pectoral fin bearing a broad, dark reddish brown bar; anal fin and first 2 dorsal fins dusky colored with weak red rays; transparent caudal fin bearing a reddish white bar at its base, proximal end with vertically aligned reddish dots. Dorsal rays III + XIII + 8-9; lateral line interrupted, 17-18 + 20-21; mandibular pores 5 + 2 + 5 (Ref. 54980).
Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 28, mean 26.4 °C (based on 225 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00246 - 0.01227), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±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 (10 of 100) .
