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).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Minimum depth from Ref. 126840. 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.
A monandric species (Ref. 55367). According to a study in Campeche Bank, females changed sex between 85.5 and 125.0 cm FL, with median length of 103.3 cm FL. At 114.5 cm FL, 50% of the females in the sample had transformed into males. Age at sex change = 15.5 years (Ref. 55367).
