Potamotrygon sp. “Pearl Ray” belongs to the Potamotrygonidae family. The patterning of this “species” is highly variable, with no two examples appearing the same. In general, Pearl rays have patterns which are made up of lines with dots or small donuts in the center of these lines. These patterns connect all over the stingray, producing like a “Spiderweb” kind of effect. Some have golden markings, while others are almost white. Not only do patterns vary in color, even the base colors of the stingrays vary from light whitish tones to dark brownish black tones.
