More Info


Endemic to southern Australian from about Lakes Entrance, Victoria, to Albany, Western Australia, including northern Tasmania. Inhabits sandy areas around seagrass beds and shallow rocky reefs in depths to 50 m - often resting partly buried in sand. 


Body extremely depressed; tail rounded in cross-section, moderately short (67-72% disc length), lateral skin folds absent. Disc oval, slightly longer than wide, broadest part immediately behind level of spiracles, anterior edge rounded; snout fleshy, tip rarely extended; eyes small (18-20% of distance between snout tip and middle of lower jaw); posterior margin of spiracles rounded; mouth small, 9-12 papillae on mouth floor; internasal flap skirt-shaped, posterior angle not extended into distinct lobe; posterolateral border of nostrils not extended into distinct lobe and not forming flattened tentacle; five pairs of gill slits on underside of disc. 
Skin smooth. 
Dorsal fin present on the tail before the venomous spine; anal fin absent; caudal fin short, deep.


Presumably feeds on benthic invertebrates and fishes.


Little is known of the biology of the Spotted Stingaree. Females give birth to live young. Stingarees are aplacental viviparous, meaning that the embryos emerge from eggs within the uterus and undergo further development until they are born. After emerging from their egg cases, the embryos are initially sustained by their yolk, and later by histotroph, a "uterine milk" produced by the mother. 


Ocasionally taken by otter trawl and gillnet as bycatch  in commercial fisheries in southeastern Australia. 


The Spotted Stingaree is often misidentified by divers as the young of the Smooth Stingray (Bathytoshia brevicaudata).
