زيست شناسي     واژه نامه (بعنوان مثال 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).
