An inshore species, but apparently occurs also in rivers (Ganges at Allahabad and rivers of eastern Uttar Pradesh, but not in Velar estuary). Ascends into the upper end of the tidal zone (Ref. 12693). Feeds on fishes, crustaceans, amphipods, occasionally polychaetes, tunicates and small amounts of algae and diatoms.
