Feeding behavior of the Neotropical freshwater stingray Potamotrygon motoro (Elasmobranchii: Potamotrygonidae) [PDF]
Neotropical Ichthyology, 2012 The feeding mechanisms of elasmobranchs and their functioning have been receiving growing scientific attention, although less emphasis has yet to be directed towards batoid species. The present study investigated the use of orobranchial musculature during prey capture and processing behavior in Potamotrygon motoro.

Neotropical freshwater stingrays (Potamotrygonidae) are conspicuous components of the South American ichthyofauna, and may be regionally important as an economic resource. The smallest individuals are exploited in ornamental fisheries, while large individuals are caught in consumptive fisheries for their meat or liver oil.

Stingers in a strange land: South American freshwater stingrays (Potamotrygonidae) in Singapore
Biological Invasions, 2009South American freshwater stingrays of the family Potamotrygonidae have long been popular worldwide as ornamentals in the aquarium trade. Despite this, there have so far not been any reported cases of their establishment elsewhere in the world. Here, we document the ocellate river stingray, Potamotrygon motoro, as having established itself in Singapore.

Systematic implications of brain morphology in potamotrygonidae (Chondrichthyes: Myliobatiformes)
Journal of Morphology, 2015ABSTRACTThe gross brain morphology, brain proportions, and position of cranial nerves in all four genera (Potamotrygon, Plesiotrygon, Paratrygon, and Heliotrygon) and 11 of the species of the Neotropical stingray family Potamotrygonidae were studied to provide new characters that may have a bearing on internal potamotrygonid systematics.
