   The dorsal surface is dark blue or black with white spots, the ventral side is white. The characteristic shape of the flat snout resembles a duck's bill. The tail is longer than that of other rays and carries 2-6 poisonous spines located just behind the ventral fins. There is a small dorsal fin. On the underside of the long and wing-shaped pectoral disc are five small gill slits, nostrils and a mouth.
