The Atlantic stingray is a small species, reaching a maximum disc width size of around 14.5 inches. They are light brown or yellow in color dorsally and white ventrally. Their rostrum, or snout, is elongated compared to other stingray species. Their gills are located ventrally, with two spiracles located dorsally next to the eyes. Atlantic stingrays have a venomous tail spine, or barb, which is serrated. It is located about one third of the way down their tail. They shed and replace these barbs throughout the year. Males can be distinguished from females by two claspers located with the pelvic fins.
