About Urobatis concentricus Osburn & Nichols, 1916
Urobatis concentricus has a light brown dorsal region, with whitish spots or patches across its dorsum and around its pectoral fins. It can be distinguished from other species in the genus Urobatis by its pupillary operculum (a structure that covers the eye), and by two dark lines arranged in concentric rows. This species is commonly called the bullseye stingray. It is venomous, with a sting spine located on its tail that typically measures between 27 and 30 mm in length.
