Biologi     Ordlista (t.ex. epibenthic)

Inhabits open water but often seen swimming near outer reef walls or deep clear-water slopes (Ref. 48637). Found mostly in shallow reef waters where it forms large schools. Feeds on crustaceans and fishes, particularly clupeoids (Sardinella and Thrissocles), but also other fishes such as Sphyraena and Balistes. Marketed canned and frozen (Ref. 9684). Its flesh is mild and pleasantly flavored, but brushed with lemon juice prior to cooking to remove the ammonia-like smell (Ref. 9684).
