Any of various marine fishes of the order Rajiformes or Batoidei, having cartilaginous skeletons, horizontally flattened bodies, and narrow tails. Any of 300-350 mostly marine species of cartilaginous fish (order Batoidei) found worldwide and classified as electric rays, sawfishes, skates, and stingrays. Many species are slow-moving bottom-dwellers. The gill openings and mouth are on the underside of the flattened body. Winglike pectoral fins extend along the sides of the head. All but electric rays have a long, slender tail, often with saw-edged, venomous spines, and rough, often spiny, skin.
