簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 13; 背的軟條 (總數) : 10; 臀棘: 7; 臀鰭軟條: 9; 脊椎骨: 13. A brown band running diagonally from nape to chin; another from 4th-5th dorsal spine base to pectoral fin base; ocular and shoulder bands spotted with blue; a zone of silvery yellow posterior and adjacent to the shoulder band. Preopercular angle 100°-111°; cheek scalation variable from few to almost fully scaled; midline of thorax fully scaled, sometimes with a row missing from pelvic ridges. A prominent rim or short tube encircle the anterior nostril, with a little peak on it posteriorly. Spines stout, fairly pungent and venomous.

生物學特性     字彙 (例如 epibenthic)

Inhabits shallow coastal waters, around hard coral reefs and areas of sand with patches of rock and soft coral. Tolerant of murky waters. Larger juveniles and adults occur in pairs in coastal reef flats, slopes and estuaries . Small juveniles are found in mangroves and enter freshwater, moving to reefs usually in small groups among corals (Ref. 48637). Feed on benthic seaweeds (Ref. 9813).

堅硬的珊瑚礁與點綴著礁石與軟珊瑚的沙地周圍, 棲息於沿岸淺水區。 可以忍受混濁的水。 較大的稚魚與成魚成對出現在海岸的礁石平臺,斜坡與河口。 小的稚魚被發現於紅樹林而且進入被移動到礁的淡水通常群集成小群魚群在珊瑚之中.(參考文獻 48637) 捕食水底的海草。 (參考文獻 9813)
