|Common Name||Brazilian Electric Ray, Small Electric Ray, Spotted Torpedo Ray, Torpedofish and Trembler|

The Lesser electric ray, (Narcine bancroftii), also known as the Brazilian electric ray, small electric ray, spotted torpedo ray, torpedofish or trembler, is a species of numbfish in the family Narcinidae.
This species of ray has a near-circular body and a short tail. It grows to approximately 45 centimeters (18 in) long, and 20 cm (8 in) wide, with colouration ranging from dark brown to reddish orange. It has irregular rings, sometimes oval in shape. The ventral surface ranges from white to greenish. It has tooth rows that vary in number from 17 to 34 in each jaw. This depends on the size of the specimen.
It has two electric organs, elongate in shape, that run from the front of the eyes, down to the rear end of the disc. These organs can generate a peak voltage of about 14 to 37 volts, which they use to stun prey and to defend themselves.
This species is found in the Gulf of Mexico, and in the coastal waters of the western Atlantic Ocean from northeastern Brazil to North Carolina. It is also common in the Caribbean Sea and the West Indies.
The lesser electric ray is most commonly found under sand or mud, in intertidal shallow waters, but has been found at depths of up to 180 feet (55 m).
This species is nocturnal. It remains motionless during the daytime, and forages for food in the substrate at night.
