Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 9; Rückenflossenweichstrahlen (insgesamt): 10; Afterflossenstacheln 3; Afterflossenweichstrahlen: 9. Median predorsal scales 2 to 4 (may be obscured by hump); scales on cheek scale rows 1(4-6), 2(3-6), 3(1-2) (Ref. 9793). Sometimes confused with the humphead wrasse or other 'humphead' parrotfishes (Ref. 1602). Unlike the wrasse, it has a vertical head profile, and unlike other parrotfishes, it is uniformly covered except for the leading edge of the head which is often light green to pink, and has a nodular outer surface to its beak (Ref. 1602). The primary phase is a dull gray with scattered white spots, gradually becoming uniformly dark green (Ref. 1602).

Juveniles found in lagoons; adults in clear outer lagoon and seaward reefs up to depths of at least 30 m (Ref. 9710). Usually in small groups. Feeds on benthic algae, live corals (Ref. 9710) and shellfishes (Ref. 58784). May ram its head against corals to facilitate feeding (Ref. 9710). Sleeps in caves and often in shipwrecks at night (Ref. 48636). The largest and wariest of the parrotfishes. Vulnerable to overfishing (Ref. 9710).
