背棘 (總數) : 9; 背的軟條 (總數) : 10; 臀棘: 3; 臀鰭軟條: 9; 脊椎骨: 25. This species distinguished by the following characters: median predorsal scales 4 (occasionally 3); 1 scale row on cheek, 1(4), below eye; pectoral-fin rays 13; relatively elongate, its depth 2.9-3.8 in SL; unique narrow dental plates composed of numerous small teeth. Colour when fresh, greenish or olive brown, often strongly mottled; male with midlateral white stripe (Ref. 9793, 90102).
Found in sheltered bays, harbors and lagoons (Ref. 48636). Inhabits seagrass areas or areas with hard substrates heavy with algal cover. Usually occur in small groups. Unlike other parrotfishes, males and females look very similar and do not change sex (Ref. 48636). Feeds on seagrasses and algae (Ref. 30573). Marketed fresh (Ref. 5284).
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
Spawns in shallow water above grassflats on the falling tide. Investigation of sexual identity of large samples suggest the species is gonochoristic (sex-reversal do not occur), the first sparid species known to be so (Ref. 1875). Also Ref. 103751.
