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. Tolerates
a wide pH range (5.2-9.1) and salinities from 0 to 100.
Mainly diurnal. Predaceous, feeding mainly on fishes and
crustaceans. Breed offshore, possibly throughout the year.
Larvae are transparent and resemble larval eels. Juveniles
commonly enter freshwater in clear or turbid water. Known to breath air, rising regularly to the surface
to do so. Cultured in ponds, the fry being sourced from the
coasts. Popular angling fish. Edible but not esteemed.
