Short description
Identification keys | Morphology | Morphometrics
Large species of Urotrygon with a round disc; tail short. Dorsal surface of disc and tail yellow-brown or tan irregularly spotted with brown or black blotches; ventral surface of disc white with lateral margins of disc and posterior border of pelvic fins tan in juveniles, dark brown or gray in adults. Small pungent denticles densely cover dorsal surface of disc and tail; denticles only slightly enlarged near midline. Pupillary operculum a small triangle, apex not reaching ventral margin of pupil.
Found in tide pools and to a depth of 85 m. Usually collected in waters shallower than 10 m.
