Discover Stingrays

Stingrays are in the same family as sharks: they have a skeleton made of cartilage, plated gills, and teeth that can be easily replaced. The best way to tell the difference between a shark and a ray is by looking for where their gills are located: sharks have gills on their sides while rays have gills on the underside of their bodies. Most rays also have their mouths on the underside of their bodies, so they never see their food. Instead, they use their keen sense of smell and special electro-sensors called Ampullae of Lorenzini that detect minute electrical signals coming from their prey’s muscles. A ray can even detect an animal hidden under sand by searching for the electrical signals given by their prey’s heartbeat! Most rays have plate-like teeth used to crush the shells of clams, crustaceans, sea urchins, and snails. Stingrays get their name from the venomous barbed stinger on their tail. Stingrays use their stinger to ward off predators for a chance to swim away or hide underneath the sand.
