Maturity: Lm ? range ? - ? cm
Max length : 23.0 cm TL male/unsexed; (Ref. 30874)
Dorsal spines (total): 11; Dorsal soft rays (total): 12 - 14; Anal spines: 4; Anal soft rays: 8 - 9. Body reddish silver, iridescent bluish above; scales finely dotted with black; spinous dorsal silvery white, with broad red margin (Ref. 4201). Five oblique scale rows on cheek; body depth 2.7-3.15 in SL; head length (HL) 2.75-3.1 in SL; snout length 4.0-4.65 in HL; interorbital width 3.6-4.05 in HL; small mouth terminal to slightly inferior, maxilla reaching from below front of iris to below center of eye, upper jaw length 2.7-3.15 in HL; premaxillary groove reaching to about a vertical at the front edge of orbit; anterior end of nasal bone rounded; medial margin of nasal bone without spinule; small nasal fossa without spinules on its edge; upper edge of suborbital bone below the eye weakly serrated, spineless laterally; short preopercular spine 1/2-3/4 orbit diameter, 4.75-6.45 in HL; 3rd-5th dorsal spine longest 2.0-2.3 in HL; 3rd anal spine 1.2-1.55 in HL (Ref. 27370).
Inhabits surge-swept tunnels and crevices of the reef margin and reef front. Rarely occurs below 30 m, but has been observed at depths of 101 to 183 m in the Hawaiian Islands (Ref. 1602); majority of specimens collected in less than 3 m, often in tide pools (Ref. 27370). Benthopelagic (Ref. 58302). It disperses at night over sand flats and open reef bottom to feed on small crustaceans, crustacean larvae, and polychaete worms. Spine of preopercle venomous. Minimum depth reported taken from Ref. 30874.
