পরিপক্কতা : Lm? range ? - ? cm Max length : 130 cm TL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 9710); common length : 70.0 cm SL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 9793); সবের্াচ্চ প্রকাশিত ওজন : 46.0 kg (Ref. 2334)
পৃষ্ঠীয় কাঁটা (মোট ) : 9; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 10; পায়ূ কাঁটা : 3; পায়ূর নরম পাখনা্তুন্ড: 9. This species is distinguished by the following characters: median predorsal scales 2-4 (may be obscured by hump); 3 scale rows on cheek, 1 (4-6), 2 (3-6), 3 (1-2); pectoral-fin rays 16 or 17; steep profile distinctive; nodules on teeth unique (Ref. 9793); prominent bump on forehead of adult (evident at least 25 cm TL); deep body 2.0-2.5 in SL, with depth increasing with growth; Colour of juveniles brownish to green with 5 vertical rows of whitish spots on side, the primary phase is a dull gray with scattered white spots, gradually becoming uniformly dark green (Ref. 90102, 1602). Body shape (shape guide): fusiform / normal; Cross section: compressed.
Juveniles are found in lagoons while adults inhabit clear outer lagoon and seaward reefs up to depths of at least 30 m (Ref. 9710). They ‘sleep’ in caves and often in shipwrecks at night (Ref. 48636). They are usually in small groups feeding on benthic algae, live corals (Ref. 9710) and shellfishes (Ref. 58784). They sometimes ram their head against corals to facilitate feeding (Ref. 9710). The largest and wariest of the parrotfishes. Assessments showed their vulnerability to overfishing (Ref. 9710). Minimum depth reported taken from Ref. 128797.
