Economic Importance and Threats
Importance:  Commercial
(Fisheries)
Threats:  Anthropogenic
(Giant devilrays are also accidentally captured in longlines, purse seines, trawls and fixed traditional tuna traps “tonnare”. They are also occasionally caught as bycatch. Their epipelagic habits make devilrays particularly vulnerable to oil spills and to disturbance from high levels of maritime traffic.)

Ecology
Habitat:  Pelagic
Trophic Level:  Tertiary Consumer
Prey:  Pelagic fishes and crustaceans
IUCN Status:  Endangered
