Found in shallow inshore coastal waters over silty bottoms (Ref. 30573, 90102). Young enters mangrove estuaries or silty reef areas (Ref. 4833, 90102). Searches for prey using a protruding pipette-like mouth or by sieving potential food through their gill rakers (Ref. 26569). Feeds on small fishes, shrimps, other crustaceans, and polychaetes. Sold fresh and dried salted; also made into fishmeal.
