Elasmobranchii (sharks and rays) > Myliobatiformes (Stingrays) > Potamotrygonidae (River stingrays) > Potamotrygoninae
Etymology: Potamotrygon: Greek, potamos = river + Greek, trygon = a sting ray (Ref. 45335).
Eponymy: William Charles Schroeder (1894–1977) was an American oceanographer and ichthyologist. [...] (Ref. 128868), visit book page.

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

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Assuming Fec<10).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).
