There are more than 500 types of stingrays and skates on the sea and rivers. Their closest relatives are sharks. Just like sharks, they don’t have hard bones. Their frames are made from cartilage. This is what changes stingrays can be launched in the ocean. For swimming, they flap fins like birds. You can try to use the sheets named Get Our Stingray Coloring Page to get the picture of a stingray.
