Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 10 - 11; Anal spines: 1; Anal soft rays: 11. This species is characterized by the following, D VI+I,10-11; A I,11; pectoral-fin rays 15; longitudinal scale series 27; cheek scales extending nearly to a vertical at anterior edge of orbit; median predorsal scales extending to posterior interorbital space; fully scaled prepectoral area; 2+4 gill rakers; body depth at origin of pelvic fins 3.9-4.25 in SL; very compressed body, width 1.55-1.8 in body depth; head length 3.25-3.3 in SL; first dorsal fin higher than second, with longest spine 1.25-1.5 in HL; caudal fin is longer than head, 2.7-2.8 in SL (Ref. 82658); moderately large Gnatholepis (up to 58 mm SL) with nape midline scales always cycloid and most of predorsal scales cycloid; body pale with 6-8 rows of staggered dark brown spots, mid-lateral spots may be largest; transverse black line on the upper part of the eye joining somewhat oblique to curved black line or bar crossing cheek and ending well behind end of jaw; third to fourth first dorsal fin spines longest, fin with square to rectangular appearance when extended; lateral scales 26-29, usually 27; 9-11 predorsal scales (usually 10), all cycloid (Ref. 92171).
Inhabits mud-sand bottoms with Caulerpa green alga in 1-12 m (Ref. 90102).

Estimates based on models
Preferred temperature (Ref.
123201): 23.5 - 29.3, mean 28.6 °C (based on 995 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00442 - 0.02163), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
