Ecology of Megalops cyprinoides
 
Main Ref. Coates, D., 1987
Remarks Adults are generally found at sea, but young inhabit river mouths, inner bays, and mangrove forests. In freshwater, it occurs in rivers, lagoons, lakes, and swampy backwaters (Ref. 2847). Tolerate salinities from 0 to 100. Mainly diurnal (Ref. 7017). Predaceous, feeding mainly on fishes and crustaceans (Ref. 5213). Breed offshore, possibly throughout the year. Larvae are transparent and resemble larval eels (Ref. 13337). Juveniles commonly enter freshwater (Ref. 48635). Also in Ref. 9137.
