Remarks | Pelagic species which lives in schools near the surface of the water (Ref. 35381). Found over soft muddy bottoms. Juveniles inhabit the lower part of streams in estuaries, adult are found more upstream (Ref. 35381). Has no teeth in its jaws but possesses many long gill rakers that are used as a sieve for feeding on planktonic crustaceans like cladocerans, copepods and ostracods (Ref. 35381, 6868); also feeds on debris (Ref. 35381). Appears to follow the plankton's vertical movements during the day. |
