Pacific Electric Rays have two kidney-shaped electrical organs that lie within their wings. The ray wraps its wings around its prey and stuns it with an electrical charge that reaches up to 50 volts.

“We are thrilled with the new Pacific Electric Ray and thankful for the opportunity to introduce it at Aquarium of the Bay,” stated John Frawley, General Manager of Aquarium of the Bay. “This new species helps further our efforts to educate local Bay Area residents and visitors on the diverse aquatic life of the San Francisco Bay and surrounding waters.”

The ray’s genus name, torpedo, is derived from a Latin word meaning “numbness” in reference to the effect of the electric organ. The species name, californica, references California, where the animal was first discovered. Ancient Romans and Greeks were also intrigued by the electrical shocks of the Pacific Electric Ray. A Roman physician recorded applying the animals to patients’ bodies to cure ailments such as headaches and gout.

Pacific Electric Rays are found in waters from British Columbia down to Baja California. They live in the sand and mud in shallower waters along with in kelp beds that can reach depths of up to 900 feet. Pacific Electric Ray’s are ovoviviparous, meaning they bear young from eggs in the female's body. They are the only Pacific ray that lacks spines or prickles.
