Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) > Myliobatiformes (Stingrays) > Potamotrygonidae (River stingrays) > Potamotrygoninae
Etymology: Potamotrygon: Greek, potamos = river + Greek, trygon = a sting ray (Ref. 45335).

Issue
Spelled Potamotrygon schuhmacheri in the title of the original descriprion, but Potamotrygon schühmacheri in the text, and wrongly emended by Taniuchi (1982) to Potamotrygon schuemacheri. Reproductive biology unknown. Additional reference: Compagno & Cook (1995). Possibly a junior synonym of P. histrix.

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).
营养阶层 (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  非常低的, 最小族群倍增时间超过14 年 (Assuming Fec<10).
Fishing Vulnerability (Ref. 59153):  High vulnerability (58 of 100).
