FBname: Shark mackerel
Remark: Date Eschmeyer, pers. comm. Correction to <i>Grammatorcynus</i> is probably unjustified (Ref. 1830).
Comments: Form schools near individual bays and reefs in Barrier Reef waters.  With the rising tide, they move into shallow water over the reef flats, feeding on schools of clupeoid fishes that concentrate there.  Utilized as a food fish.
