Most stingrays have one or more thorny stings (modified from skin darts) on the tail, which are used exclusively for self-defense. Stinger can reach a length of about 35 cm, and the bottom has two fangs like a groove with a poison gland. The stinger is covered with a thin layer of skin covering the veil, where the toxins are concentrated. some members have no sting.The stingrays are common in tropical and subtropical coastal marine waters around the world, and also include species found in warmer ocean climates, such as Dasyatis thetidis, and those found in deep seas, such as Plesiobatis daviesi. River jellyfish, and a number of whiptail stingrays (such as Niger). Most mylobatoids are demersal (next to the lowest zone), but some, such as pelagic stingray and eagle rays. the benefits of stingrays
