Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

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.

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

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).
