Short description

Dorsal spines (total): 11; Dorsal soft rays (total): 15-17; Anal spines: 3; Anal soft rays: 11 - 13. Distinguished by the following characteristics: Side body has rectangular dark gray blotches. Outer third of second dorsal, anal and caudal fins black. Edge of preopercle smooth, without pronounced lobe at angle; 17-24 total gill rakers (Ref. 26938); depth of body 3.3-3.5 times in SL; head length 2.5-2.8 times in SL; evenly rounded preopercle, without distinct notch or lobe at the angle; subequal sizes of anterior and posterior nostrils (Ref. 89707).

A solitary species (Ref. 26340) inhabiting rocky and coral reefs (Ref. 9710). Adults feed primarily on fishes; juveniles mainly on crustaceans. Oviparous (Ref. 205). A protogynous hermaphrodite (Ref. 55367). Forms spawning aggregations (Ref. 55367). Common but difficult to approach (Ref. 9710). Marketed fresh and its flesh is of excellent quality.
