Narcine is a genus of electric rays in the family Narcinidae. These species have a rounded pectoral fin disc and two dorsal fins, the first usually smaller than the second and placed behind the pelvic fin bases. The tail is longer than the disc and has a lateral fold. The spiracles are close behind the eyes, the nasal flaps are merged into a flap in front of the mouth. The teeth are nearly flat, with a central point.[2]
