Pre-copulatory bite wounds as evidence of aggressive competition for mating in the neotropical freshwater stingray Potamotrygon motoro

Acta Amazonica, 2022
Reproductive aspects of Amazonian freshwater stingrays are still poorly studied, however, it is known that the copulatory behavior in some species is related to the hydrometric seasons (high and low water).

Ingestion of catfish by freshwater stingray: possible mistake or inexperience [PDF]

Biota Neotropica, 2009
We report an individual of the freshwater stingray Potamotrygon falkneri caught with a decomposing catfish, Pimelodella gracilis, stuck in its oral cavity. The ingestion of catfishes by stingrays is possibly rendered difficult or hazardous due to the serrated spines on the dorsal and pectoral fins of this prey type.
