Mobula kuhlii, the shortfin devil ray, is a species of ray in the family Mobulidae. It is endemic to the Indian Ocean and central-west Pacific Ocean. It ranges from South Africa, Mozambique, Tanzania and the Seychelles in the west to the Philippines and Indonesia in the east, and southward to the northern coast of Australia.

It gathers its food by swimming with its mouth open and passing the water over its gill rakers which filter out the food particles. It is an ovoviviparous fish and has the lowest rate of reproduction of any of the elasmobranchs. A litter usually consists of a single pup and... Wikipedia →

Possible
About 20% of wildlife watchers report an Ox Ray sighting in Raja Ampat on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 12 sharks and rays we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report an Ox Ray in Raja Ampat on a given day, against under 5% in April–May and December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Ox 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.
Only Raja Ampat, in our data
Raja Ampat is the only park on Wallace's Line with enough records to rate Ox Ray sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Mobula
The closest relatives of the Ox Ray that you can see in Raja Ampat (genus Mobula, Devil Rays) are Reef Manta Ray (about 70%) and Oceanic Manta Ray (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ox Ray is recorded against all the sharks and rays logged in Raja Ampat (9 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.
