Production of live offspring following unilateral (left) ovariectomized Potamotrygon rays (Potamotrygon castexi, Potamotrygon leopoldi, and Potamotrygon motoro)

Journal of the American Veterinary Medical Association, 2023
Abstract OBJECTIVE To evaluate the surgical technique and subsequent clinical observations (reproductive and ultrasound findings) of left unilateral ovariectomy in 3 species of Potamotrygon rays—Potamotrygon castexi, Potamotrygon leopoldi, and Potamotrygon motoro—for reproductive management. ANIMALS Between 2018 and 2019, multiple Potamotrygon rays (

Serial reversal learning in freshwater stingrays (Potamotrygon motoro)

Animal Cognition, 2019
Serial reversal learning is considered a reliable approach for the testing of behavioral flexibility, and animals that inhabit fluctuating habitats and different environments are expected to possess behavioral and cognitive flexibility. The ocellate river stingray (Potamotrygon motoro) is one such species.

Social learning in Cartilaginous fish (stingrays Potamotrygon falkneri)

Animal Cognition, 2013
Social learning is considered one of the hallmarks of cognition. Observers learn from demonstrators that a particular behavior pattern leads to a specific consequence or outcome, which may be either positive or negative. In the last few years, social learning has been studied in a variety of taxa including birds and bony fish.
