Main Ref. Skelton, P.H., 2001
Remarks Occurs in the sea, but found mostly in estuaries; also found in landlocked brackish and freshwater lagoons (Ref. 93596), also rivers and lakes (Ref. 188). Entire life cycle is completed in the estuary (Ref. 32693). Feeds chiefly on zooplankton by filtering or selecting individual organisms from the water column (Ref. 7248, 52193). It can tolerate salinities under 4 ppt and of up to 52.6 ppt (Ref. 32693).
