Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8. Characterized by mottled brown overall color; presence of broad dark grey bar below each dorsal fin; basal part of dorsal and caudal fins with dark spots forming bands; upper 5-7 pectoral rays partly free of membrane, uppermost with 5-7 branches; rounded caudal fin; longitudinal scale series 35-39; predorsal scales 21-23, extending to interorbital space; presence of scales on cheek and opercle; ctenoid body scales, becoming smaller and cycloid on head and anterior body; depressed head, width greater than depth; depth of body 4.2-5.0 in SL (Ref. 90102).
Benthic in rocks and coral of shallow waters (Ref. 58302). Also occurs in rocky pools of intertidal reef flats and exposed rocky shores in 0-2 m (Ref. 90102).

Estimates based on models
Preferred temperature (Ref.
123201): 24.9 - 29.3, mean 28.2 °C (based on 2181 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 117 [60, 245] mg/100g; Iron = 0.779 [0.394, 1.423] mg/100g; Protein = 18.9 [17.0, 20.6] %; Omega3 = 0.14 [0.06, 0.26] g/100g; Selenium = 15.2 [7.5, 32.4] μg/100g; VitaminA = 131 [36, 455] μg/100g; Zinc = 2.19 [1.45, 3.27] mg/100g (wet weight);
