(total): 0. A huge, thick, plain stingray with a bluntly angular snout, and a pectoral disc with round tips; tail thick-based and shorter than body (longer in young) with a small upper and a long lower caudal finfold, the lower not reaching the tail tip; disc smooth except for large, slender thorn on tail in front of stings; often 2 stings, the front one small, the rear one huge (Ref. 5578). Grey-brown or bluish-grey dorsally with a row small, pale blue spots at each pectoral fin base; white ventrally; tail plain (Ref. 5578). The caudal fin is replaced by a long whip-like tail (Ref. 26346). Tail shorter than or the same length as the disc (Ref. 26346).
Indo-West Pacific: southern Mozambique and South Africa (Ref. 5578), New Zealand, and temperate and subtropical coasts of Australia. Accounts of this species from Thailand may be of the closely related Dasyatis matsubarai.
Occurs offshore, on the outer shelf and uppermost slope; sometimes close inshore (Ref. 5578), in very shallow ( 0 m) depths (Ref. 26346). Found on sandy bottoms, in bays, harbors, and near rocky reefs (Ref. 12951). Often in aggregations (Ref. 12951). Feeds on fishes, bivalves, squid, and crustaceans (Ref. 12951). Ovoviviparous (Ref. 50449). Reputed to be the largest stingray in the world weighing more than 350,000 g (Ref. 6871). Frequently raises its tail in a scorpion-like fashion when approached, but is considered more as inquisitive rather than aggressive (Ref. 6871). The barbed tail however can inflict a severe or potentially fatal wound (Ref. 6871). Sometimes caught by anglers (Ref. 5578).
