Round Ribbontail Ray Identification Guide

Key identification features

• Large, thick, rounded disc with a smooth, almost circular outline
• Grayish, olive, or brownish background covered in dark blotches or spots that often fade or become fewer with age
• Thick, muscular tail shorter than many other stingrays, bearing a prominent fin fold running along its length, giving a ribbon-like appearance
• One or more long, serrated venomous spines near the base of the tail
• Can grow quite large, among the bigger reef-associated stingrays, with a heavy, robust build

Common look-alikes

• Yellow stingrays are much smaller and have a more oval disc with finer speckling rather than large, dark, irregular blotches.
• Other ribbontail or fantail rays share the finned tail shape but typically show different base coloring, such as a more uniform gray without heavy blotching.
• Eagle rays have a distinct diamond-shaped disc with a projecting head and pointed pectoral wingtips, quite different from the round, blotched disc of this species.

Where you'll see one

This ray is found on sandy patches near coral reefs, lagoons, and occasionally deeper reef slopes throughout the Indo-Pacific region. It is often seen resting motionless on the bottom during the day, partially covered by sand, and becomes more active at night while foraging.
