What characterizes the striking disc coloration of *P. leopoldi*?
Answer
Prominent white or yellowish circular markings on a dark background
The physical signature that immediately sets *Potamotrygon leopoldi* apart is its high-contrast coloration. The body presents a dark background, frequently described as black or very dark grey. Scattered across this dark canvas are noticeable, distinct circular markings that are either white or yellowish in color. Observers often count between five and ten of these spots, which provides a stark visual contrast when compared to many other species within the *Potamotrygon* genus that might possess more subtle patterns or uniform coloring.
