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).
