Issue
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).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Assuming Fec<10).
Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).
