- Abstract
This is the first report of morphological abnormalities in embryos of Roger's roundray Urotrygon rogersi in the Tropical Eastern Pacific. The embryos of two pregnant females caught in artisanal shrimp trawl nets had incomplete, deformed pectoral fins that were separated from the head along the anterior margin. Moreover, one of the embryos presented a fin-like extension in the dorsal surface. Although the mouths of the embryos were normal and well-formed, the malformations in the pectoral fins could affect their mobility, limiting their capacity to capture preys and escape of predators.
