The bluespotted ribbontail ray (Taeniura lymma) is a species of stingray in the family Dasyatidae. Found from the intertidal zone to a depth of 30 m (100 ft), this species is common throughout the tropical Indian and western Pacific Oceans in nearshore, coral reef–associated habitats. It is a fairly small ray, not exceeding 35 cm (14 in) in width, with a mostly smooth, oval pectoral fin disc, large protruding eyes, and a relatively short and thick tail with a deep fin fold underneath. It can be easily identified by its striking color pattern of many electric blue spots on a yellowish background, with a pair of blue stripes on the tail.
At night, small groups of bluespotted ribbontail rays follow the rising tide onto sandy flats to root for small benthic invertebrates and bony fishes in the sediment. When the tide recedes, the rays separate and withdraw to shelters on the reef. Reproduction is Ovoviviparity. With the females giving birth to litters of up to seven young. This ray is capable of injuring humans with its venomous tail spines, though it prefers to flee if threatened. Because of its beauty and size, the bluespotted ribbontail ray is popular with private aquarists despite being poorly suited to captivity. Wikipedia →

Likely
About 60% of wildlife watchers report a Reef ray sighting in Komodo National Park on a given day, based on 36 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 8 sharks and rays we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
November
In that month about 90% of wildlife watchers report a Reef ray in Komodo National Park on a given day, against about 10% in May, the lowest month. February has too few records to rate.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Reef ray sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 4
Of the 4 parks where we can rate Reef ray sightings, Komodo National Park ranks 2nd at about 60%. The best odds are in Ningaloo Marine Park (Australia, about 70%). All parks ranked.
Same family: Dasyatidae
The closest relatives of the Reef ray that you can see in Komodo National Park (family Dasyatidae, Whiptail Stingrays) are Australian Bluespotted Maskray (about 40%) and Mangrove Ray (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Reef ray is recorded against all the sharks and rays logged in Komodo National Park (36 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.
