পৃষ্ঠীয় কাঁটা (মোট ) : 11; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 12 - 15; পায়ূ কাঁটা : 4; পায়ূর নরম পাখনা্তুন্ড: 9. Body color brownish to purplish red; head primarily red; upper part of opercular membrane blackish; each scale with vertical silvery white line. Four to five oblique scale rows on cheek; body depth 2.3-2.7 in SL; head length (HL) 2.4-2.85 in SL; snout length 3.75-4.35 in HL; maxilla extending posteriorly from below front of pupil to below center of the eye, upper jaw length 2.7-2.85 in HL; premaxillary groove about a vertical at front edge of orbit; anterior end of nasal bone with 2 diverging spines; medial margin of nasal bone spineless (however, a Seychelles specimen 20.6 cm has one small spinule on the edge); 1-3 spinules on anterior and posterior margins of nasal fossa; suborbital bones' upper edge smooth anteriorly, becoming slightly serrate posteriorly (serrae as recumbent spinules); adults' preopercular spines long, 2.85-3.8 in HL (at least equal to orbit diameter). 2 opercular spines with the lower nearly as long or equal to the upper spine; 4th dorsal spine longest, .5-2.95 in HL; membranes of spinous dorsal fin not incised; 3rd anal spine 1.5-1.7 in HL (Ref. 27370). Has a high body similar to S. spiniferum, but differs in coloration and does not get as large.
Uncommon in atoll reef flats, lagoon patch reefs, and steep outer reef slopes. Solitary and secretive species, occasionally seen in small crevices in clear water habitats (Ref. 48635). Strictly nocturnal, feeds mainly on benthic crabs and shrimps. Spine of preopercle is venomous. Usually among rich coral growth (Ref 90102).
