Stingrays belong to the Dasyatidae family. Among them are the smooth butterfly ray, the southern stingray, the roughtail stingray, the spiny butterfly ray and the round stingray.
Stingrays are distinguished by not just the stinger in the tail, but by a depressed body disk, pectoral fins that extend past their mouths and no dorsal fins. Some stingrays have a flap of skin on the tail and others, like the roughtail, have tubercules or prickles on their body and tail. Other species, like the southern stingray, have a long, whiplike tail. Despite the danger of the sting, most stingrays are docile.
