Eyeless morphotype in the southern stingray (Dasyatis americana): a non-lethal and frequent abnormality from the southern Gulf of Mexico

Elasmobranchs are active predators that depend on a highly developed visual system. The eyes of the southern stingray, Dasyatis americana, are adapted to a changing light environment in coastal zones. In this study we use morphological characters and molecular methods (mtDNA COI) to describe an eyel...
