Bathytoshia brevicaudataSmooth stingray | Shorttail Stingray | Dasyatis brevicaudata
Temperate Africa, Temperate Australasia, Tropical Indo-Pacific
Looks similar to another massive southern Australian ray, the black stingray Dasyatis thetidis, but has a series of small white spots across the flaps and lacks spines down the middle of the back. The smooth stingray is not aggressive but can be inquisitive, so should be treated with great caution as the large venomous spine on the tail can cause fatal wounds.
