Pacific electric ray females are larger than their male counterparts, measuring 164 cm (65 in) in width (their pectoral disc) and a total of 137 cm (54 in) in length. Male Pacific electric rays are 92 cm (36 in) in width and 110 cm (43 in) in length. [15] Both sex's pectoral fin disc width is roughly 1.2 greater than their length. [13]
Torpedo is a genus of rays, commonly known as electric rays, torpedo rays, or torpedoes. They are slow-moving bottom-dwellers capable of generating electricity as a defense and feeding mechanism.
The electric rays are a group of rays, flattened cartilaginous fish with enlarged pectoral fins, composing the order Torpediniformes / t ɔːr ˈ p ɛ d ɪ n ɪ f ɔːr m iː z /. They are known for being capable of producing an electric discharge , ranging from 8 to 220 volts , depending on species, used to stun prey and for defense. [ 2 ]
A ray can emit a shock into the body of a prey animal to stun it and make it easier to capture and eat, or into the body of a predator. Tissue from electric rays is often used in neurobiological research because of its unique properties. Torpedo rays are flat like other rays, disc-shaped, with caudal fins that vary in length.
Tetronarce is a genus of rays, commonly known as electric rays. They are slow-moving bottom-dwellers capable of generating electricity as a defense and feeding mechanism. Tetronarce species tend to attain a much larger size (up to 180 cm TL ) than Torpedo species, which are usually small to moderate sized (range from 25 to 80 cm TL ) electric rays.

The majority of electric rays have a distinctive style of low speed swimming that consists of periodically moving up in the water column then gliding back down. Unlike Rajiformes and Myliobatiformes their propulsion comes solely from the movement of their caudal fin, which is much more developed than in skates and rays. The disc portion of ...
