An enormous stingray with a deep smooth rhomboidal disc, diagonal rows of pale pores on each side of the head, and a short depressed tail tapering towards the sharp, finely serrated spine. The tail lacks a dorsal fin, and is armed with large tubercles and thorns. The Smooth Stingray is greyish-brown above, with a pale underside, and somewhat darker above the eye and on the tail tip.

The large serrated spine on the tail is venomous, and is used for defence. Smooth Stingrays are potentially very dangerous to humans due to their large size, and have been responsible for very painful injuries and at least one death in Australia.

This species was previously known as Dasyatis brevicaudata.

More Info


Widespread in temperate waters of southern Australia, from about Maroochydore in southern Queensland, to Shark Bay, Western Australia, including Tasmania. Elsewhere, the species occurs in South Africa and New Zealand.

Smooth Stingrays inhabit silty or sandy areas in harbours, shallow coastal bays, estuaries, large inlets, coastal reefs and offshore islands. Individuals sometimes congregate in caves and under large overhangs.


Maximum total length (TL): 4.3 m
Disc width (DW): more than 2.1 m
Max weight: 350 kg 


Feeds on bottom-dwelling fishes, crustaceans and bivalve molluscs, which are often dug up from the sediment.


Little is known of the biology of this species. Smooth Stingrays are aplacental viviparous, and females produce litters of 6-10 young, born at about 36 cm DW (disc width).


Taken as bycatch in inshore trawl, Danish seine, snapper longline and purse seine fisheries. Also taken by recreational line fishers, and on set lines, drag nets and set nets. Individuals without tails are often seen by divers, suggesting that they often survive capture and tail removal by fishers.


IUCN Red List : Least Concern
The species is taken in a variety of commercial fisheries throughout its range, and usually released or discarded. 

Similar Species

The similar Black Stingray, Bathytoshia lata, differs in having thorn-like denticles along the dorsal midline of the disc, and lacks white spots. B. lata was previously called Dasyatis thetidis. 


The specific name brevicaudata is from the Latin "brevis" (= short), and "cauda" (= tail) in reference to the relatively short tail of this species.
