The common eagle ray or bullray (Myliobatis aquila) is a species of fish in the family Myliobatidae. It inhabits the eastern Atlantic Ocean (North Sea to South Africa), the Mediterranean Sea and the south-western Indian Ocean.
The common eagle ray reaches up to 183 cm (6.0 ft) in total length with a disc width up to 80 cm (2.6 ft), though most specimens are smaller. Females grow to be larger than males. The dorsal surface is brown or black while the ventral surface is white. It has a rhomboidal disc with a pair of large, triangular pectoral fins projecting on either side, and a single dorsal fin. The blunt snout is rounded and the tail is long and slender, with a large spine at its base but no tail fin. On average, males have 72 spine serrations and females have 66 spine serrations. The spine makes about 70% of the male's length and 65% of the female's length. The mid dorsal groove, which contains the glandular tissue necessary for venom injection, extends along 10–40% the tail. It has one or two excretory channels for the venom.
This species occurs in the eastern Atlantic Ocean, including the North Sea, from the British Isles to South...

Likely
About 50% of wildlife watchers report a Common Eagle Ray sighting in Corsica Regional Natural Park (Parc naturel régional de Corse) on a given day, based on 39 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 90% of wildlife watchers report a Common Eagle Ray in Corsica Regional Natural Park (Parc naturel régional de Corse) on a given day, against about 20% in July, the lowest month. November to February have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Eagle Ray sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Common Eagle Ray sightings, Corsica Regional Natural Park (Parc naturel régional de Corse) has the highest daily chance: about 50%. Next come Teno-Rasca Marine Strip (Tenerife) (Spain, about 30%).
GBIF citizen-science records
It is estimated from how often the Common Eagle Ray is recorded against all the sharks and rays logged in Corsica Regional Natural Park (Parc naturel régional de Corse) (39 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
