Indo-West Pacific: Delagoa Bay, Mozambique to the Cape, South Africa; common in Australia and New Zealand and reported from Japan and Korea. Also reported from Hong Kong (Ref. 12086).
Found from estuaries to edge of continental shelves over sand and sandy shell seabed (Ref. 9258). Reported to be often found in rivers (Ref. 4316). Juveniles may occur in bays (Ref. 33616). Benthic (Ref. 58302). Dorsal spine reported to be venomous (Ref. 9771). Neither anterolateral glandular grooves nor venom gland is present (Ref. 57406).
