Stingrays are carnivores that eat shrimp, clams, oysters, mussels, snails, small fish and crabs. They have strong jaws that they use to crush their prey.
Stingrays spend a great deal of time on the ocean floor, partially covered by sand or mud. Because their coloring is so similar to the colors of the ocean floor, they are well camouflaged. This allows them to avoid predators and wait for potential prey to pass. Rather than using their eyes to detect prey, stingrays rely on electrical sensors around their mouths called ampullae of Lorenzini. These organs sense the electrical charges surrounding the potential prey.
