Characterized by pale grey color grading to white ventrally; presence of blue-edged red to pink band from occiput to cheek; side of body with variable-sized brown spots on side of body and on dorsal and caudal fins; some larger spots (on shoulder region and first dorsal fin) surrounded by small blue-white spots; upper half of side of body and along base of second dorsal fin with scattered small blue-white spots; hard and pungent first dorsal spine of first dorsal fin, fifth spine forming short filaments; lanceolate caudal fin; longitudinal scale series 29-32; all scales cycloid; predorsal scales absent; depth of body 6.8-7.8 in SL (Ref. 90102).

Occurs on clear sandy bottoms with fast tidal currents. Retreats in burrows made possibly by sea cucumbers or polychaetes (Ref. 30347).

Estimates based on models

Preferred temperature (Ref. 123201): 21.9 - 29.3, mean 28.4 °C (based on 1429 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
