Electric Ray
About the Electric Ray
They can deliver electric shocks of 220 volts, enough to knock a human down. Ancient Greeks and Romans used electric rays to treat headaches and gout - the earliest recorded use of electrotherapy. They have specialized kidney-shaped electric organs in their pectoral fins. Over 60 species exist. They are ambush predators that stun prey with electricity. They can vary the strength of their shock. They are bottom-dwellers that bury themselves in sand. They are ovoviviparous. Their electric organs are modified muscle tissue. Some species can generate repeated shocks.
