    • Biology

    Inhabit continental shelf waters including estuaries, bays and inlets (Ref. 6390). They school in shallow, open coastal waters, and can move over reefs in depths just sufficient to cover their bodies (Ref. 6390). Juveniles are found over soft substrates in shallow and sheltered coastal waters (Ref. 6390). They are often found over seagrass (e.g. Posidonia species) beds and in mangrove-lined (Avicennia species) creeks (Ref. 27967). Larger fish move into exposed, coastal waters, such as around rocky headlands, near reefs and the surf zone (Ref. 6390). Feeds on fishes (Ref. 2156). Minimum depth reported taken from Ref. 57178.
