This predominately marine species occasionally enters the lower reaches of freshwater systems. They are found from the Chesapeake Bay to Yucatan, Mexico. As with other stingrays, the Atlantic Stingray has a disc-shaped body with its eyes and spiracles (the opening to gills) on top of its body. Its mouth and gill slits are concealed under the body. To protect itself from predators, it has a barb on its whip-like tail.
