Thorson et al. (1983b) document the reproductive maturity for males at 32 to 34 cm DW, and at 35 to 45 cm DW for females, which can carry up to 11 fetuses per gestation. Delimitation of type-series of Potamotrygon circularis follows Hartel & Dingerkus (1997). Additional references: Thorson et al. (1983a), Compagno & Cook (1995), Ferreira et al. (1998).
