The eagle ray

It grows to a disk length of 3.5 metres (11 ft), making it one of the largest rays.

Range and habitat

It is also found in the Eastern Atlantic Ocean, off the southwest coast of Ireland and south of Portugal, as well as in the central and western Pacific Ocean. Devil fish inhabit offshore areas to the neritic zone, their range as deep as several thousand meters. In other observations studying ray abundance and habitat, giant devil rays were observed alone and occasionally in groups with a maximum of 18 rays.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Diet and breeding

Devil rays feed on planktonic crustaceans and small schooling fish, that are funneled into the mouth with cephalic flaps. The species gives birth to live young: the young hatch from their eggs inside the mother's body and emerge later when they are more fully grown.

In crisis

As of 2025, it is listed as critically endangered, mostly due to bycatch mortality in unrelated fisheries and a naturally slow reproduction rate. Its population trend is decreasing. Most of the information on the giant devil ray has been gathered through bycatch data because the species has a high bycatch mortality.

Giant devil ray mortalities are mostly reported as bycatch from swordfish nets, and occasionally reported as bycatch from longlines, purse seines, trawls, trammel nets, and tuna traps. There are many threats against the giant devil ray such as fishing, resource harvesting (being taken as bycatch in different fisheries), industrial garbage, and solid waste.

CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
