Although the giant devilray is not targeted by fisheries, it is accidentally captured at threatening levels, such as by swordfish and tuna fisheries (1) (2). A decline in habitat quality, particularly in the Mediterranean, is also likely to be impacting populations of giant devilray, though to what extent is not known (1). Its preference for inhabiting the surface of the oceans makes the giant devilray vulnerable to disturbance from maritime traffic and oil spills (1).
