Etymology: Potamotrygon: Greek, potamos = river + Greek, trygon = a sting ray (Ref. 45335).

Issue
Holotype was originally in the private collection of A. Fernandez-Yepez (AFY 51289). Distribution of this species was expanded by Castex & Yagolkowski (1970) to include the Negro river of the Amazonas basin. Note that the species we recognize as Potamotrygon schroederi does not correspond to this species in Rosa (1985a) – his “P. schroederi” actually represents a new species. Reproductive biology unknown. Additional references: Mago-Leccia (1970), Compagno & Cook (1995).

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
Widerstandsfähigkeit (Ref. 120179):  sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Assuming Fec<10).
Fishing Vulnerability (Ref. 59153):  High vulnerability (58 of 100).
