Dorsal spines (total): 11; Dorsal soft rays (total): 14 - 15; Anal spines: 3; Anal soft rays: 8. Distinguished by the following characteristics: head and body pale brownish gray, densely covered with tiny close-set dark orange-brown spots; median and paired fins spotted like body; caudal, soft dorsal and anal fins with white edge and a submarginal blackish zone; depth of body 3.2-3.6 times in SL; head length 2.4-2.6 times in SL; flat to slightly convex interorbital area, dorsal head profile with slight indentation above nostrils; preopercular angular, with enlarged serrae at the angle and a shallow notch just above the angle; upper edge of operculum straight; posterior nostril slightly larger than anterior; maxilla reaches vertical at rear edge of eye; ventral edge of maxilla with a low step-like bend one orbit diameter from rear end of bone; 2 rows of teeth on midlateral part of lower jaw; lateral body scales ctenoid, with numerous auxiliary scales; pyloric caeca about 76 (Ref. 89707).
Found over rocky bottoms (Ref. 30573); reef-associated species. Juveniles/subadults inhabits shallow waters with high coral cover. Feeds on fishes and invertebrates (Ref. 89707). Minimum depth from Ref. 58018.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00568 - 0.02430), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (41 of 100).
