Indo-West Pacific: Red Sea and South Africa to the Philippines, north to China (Ref. 33450) and Taiwan (Ref. 5193), south to northern Australia.
Found in shallow waters; common in estuaries; may enter lower reaches of rivers. Can tolerate fresh water only within a narrow temperature (23-26°C). Feeds mainly at night on crustaceans, but also takes small fishes, fish eggs and larvae in estuaries (Ref. 7248). Marketed dried, salted and fresh (Ref.97399).
