Regarding size metrics of P. leopoldi, which sex consistently grows larger?
Answer
Females
Size data explicitly indicates a pronounced sexual dimorphism in *P. leopoldi*, where females are consistently documented as growing substantially larger than males. Reports suggest that adult females can attain disc widths approaching 70 cm. In contrast, male specimens typically reach maximum disc widths closer to 50 cm. This disparity means that the largest observed total lengths and weights, such as approaching 75 cm total length and up to 20 kilograms, are generally reserved for the largest adult females, reflecting the upper limits of the species' size potential.
