The plain maskray (Neotrygon annotata) or brown stingray, is a species of stingray in the family Dasyatidae. It is found in shallow, soft-bottomed habitats off northern Australia. Reaching 24 cm (9.4 in) in width, this species has a diamond-shaped, grayish green pectoral fin disc. Its short, whip-like tail has alternating black and white bands with fin folds above and below. There are short rows of thorns on the back and the base of the tail, but otherwise the skin is smooth. While this species possesses the dark mask-like pattern across its eyes common to its genus, it is not ornately patterned like other maskrays.
Benthic in nature, the plain maskray feeds mainly on caridean shrimp and polychaete worms, and to a lesser extent on small bony fishes. It is viviparous, with females producing litters of one or two young that are nourished during gestation via histotroph ("uterine milk"). This species lacks economic value but is caught incidentally in bottom trawls, which it is thought to be less able to withstand than other maskrays due to its gracile build. As it also has a limited distribution and low fecundity, the International Union for Conservation of Nature (IUCN) has listed it as Near Threatened.
