Southern stingray. Southern stingray (Dasyatis americana) swimming over a sandy seabed. This stingray inhabits sandy and muddy seabeds from the eastern coast of North America to northern South America. It may reach a width of over a metre. The hole seen to the left of its eye is a spiracle,one of two such openings that the stingray uses to breathe when resting on the sea floor. Stingrays are named for the sharp barbs (not seen) on their tails. These contain venom and are used only for defence against predators. The sting is extremely painful,but rarely fatal to humans.
