Answer
Up to 50 centimeters or more
While size can vary depending on environmental factors and maturity, the text specifies a typical range for mature specimens of *Potamotrygon leopoldi*. Taxonomists consider the overall size, along with pattern and morphology, when defining species boundaries. Mature specimens of this species are generally noted to possess a disc width that can reach or exceed 50 centimeters. This measurement serves as one of the physical criteria used in conjunction with genetic data to confirm its specific placement within the *Potamotrygon* genus and differentiate it from other riverine stingrays.
