BLACK DIAMOND

Potamotrygon leopoldi

Originating from Brazil,  Potamotrygon leopoldi are traditionally called Polka Dot Stingray. They naturally occur in various locations along the Xingu River all the way down into the Amazon Basin, but the renowned "Black Diamond" comes from a specific location along the Xingu River near the town of Sao Felix. The main difference are the extra rows of spots a Black Diamond has as compared to a Polka Dot Ray.
