Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 32.0 cm TL male/unsexed; (Ref. 5213); common length : 20.0 cm TL male/unsexed; (Ref. 3418)
soft rays: 8 - 9. Body with dark brown to brownish red stripes, alternating with silvery white stripes. The upper 2 dark stripes often ending in an elongate dark brown spot at the base of the soft portion of the dorsal fin; the third curving downward to end at mid-base of caudal fin; the 4th ending just before the caudal peduncle; the 5th and 6th stripes converging posteriorly on lower edge of caudal peduncle; 7th and 8th ending in a dark blotch at the rear base of soft part of anal fin. Four oblique scale rows on cheek; body depth 2.6-2.8 in SL; head length (HL) 2.65-2.9 in SL; short and blunt snout, length 4.4-5.1 in HL; interorbital width 3.9-4.4 in HL; mouth terminal to slightly inferior, maxilla often extending to below center of the eye, upper jaw length 2.35-2.55 in HL; premaxillary groove often reaching above anterior edge of orbit; anterior end of nasal bone ending in a spine; surface or medial edge of nasal bone spineless; nasal fossa without spinules (occasionally large specimens with one spinule on anterior edge of fossa); upper edge of first suborbital bone with a slightly retrorse lateral spine, followed by a low ridge of recumbent spinules; preopercular spine 1.5-2.2 in orbit diameter, 3.7-5.8 in HL; 3rd-5th dorsal spines subequal, the longest 1.85-2.2 in HL; 3rd anal spine 1.25-1.5 in HL (Ref. 27370).
Indo-West Pacific: East Africa south to Mozambique (but not the Red Sea) and east to the Marshall, except the northern Marshalls (Ref. 37816) and Society islands. Recorded from the Mediterranean.
Inhabits reef flats and shallow protected reefs, often in dead reef areas (Ref. 9710). Secretive during the day (Ref. 37816).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00719 - 0.03187), b=2.98 (2.81 - 3.15), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (24 of 100) .
