The masked stingaree (Trygonoptera personata) is a common species of stingray in the family Urolophidae, endemic to southwestern Australia.

It prefers moderately deep areas of sand or seagrass some distance from shore, though it can be found in very shallow water or to a depth of 115 m (377 ft).

The diet of the masked stingaree consists primarily of polychaete worms and crustaceans, with a general shift from the latter to the former as the ray ages.

It is aplacental viviparous, with females typically bearing one pup annually and nourishing it with histotroph ("uterine milk").

A male 23 cm (9.1 in) across was designated as the type specimen; it was collected by the research trawler FRV Hai Kung from northeast of Cape Naturaliste in Western Australia on 23 April 1981.

There is a single serrated stinging spine on the upper surface of the tail, which is immediately preceded by a rather large dorsal fin.

The expanded lobes and sensory papillae adjacent to its mouth likely aid in locating and excavating such burrowing prey.

Ovulation and mating occur from mid-June to mid-July; fertilized eggs are enclosed by a delicate brown capsule and maintained in a state of diapause (dormancy) within the uterus until November.

[1][7] The scallop and prawn trawl fisheries operating off Perth and Mandurah regularly take the masked stingaree as bycatch, though only a small number of vessels are involved.

This species would potentially benefit from the implementation of the 2004 Australian National Plan of Action for the Conservation and Management of Sharks.
