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"). The 10–12-month long gestation period consists of a five-month period of suspended development for the egg, followed by rapid growth of the embryo and birthing in late April or early May. The International Union for Conservation of Nature (IUCN) has listed the masked stingaree under Least Concern. Fishing pressure on this species is largely limited to a small number of scallop and prawn trawlers. Most such incidental captures result in the ray being released alive, though it does have a tendency to abort any unborn young during capture.
