Abstract

Multiple paternity (MP) is a phenomenon observed for more than 30 elasmobranch species. The Batoidea is more specious than the Selachii, but only three studies of MP have been conducted on batoids. The occurrence of MP in freshwater stingrays was tested using microsatellite markers, which were developed for Potamotrygon leopoldi. Six mothers and their litters were genotyped, providing the first evidence of MP for Potamotrygonidae, with an MP frequency of 33%.
