A pale grey stingaree with distinctive whitish spots on the disc. the spots are arranged in a regular pattern, and each has a darker margin. The Sparsely-spotted Stingaree is widely distributed and abundant on sandy bottoms and in seagrass beds in southern Australia.
While this species is most similar to the Common Stingaree, Trygonoptera testacea, it lacks the dark mask around the eyes.
Stingarees must handled with great care as the serrated spine is venomous and can inflict a very painful wound.
