I think they are different in that they have jaws. Rays are predominantly marine and are found in all the oceans. Many are slow-moving bottom dwellers. They include, Manta ray which is one of the most known type of rays, Spotted eagle ray (pacific ocean), sting ray  among others. They are about 15 types of rays in the oceans.  Sharks, Lampreys and rays, like all fishes they are aquatic, water-breathing vertebrates with a brain and spinal cord, fins, plate-like pairs of internal gills, and paired sense organs.
