Electric eels are carnivorous fish. Their favorite foods are small fish and shrimp, and they usually eat some crustaceans and aquatic animals. In addition, if there are some large fish carcasses around, electric eels will also eat. Of course, in the absence of food, electric eels also eat some aquatic plants. However, this situation is relatively rare, because electric eels use electricity when hunting, so their predation ability is very strong.

When the electric eel preys, it will approach the fish school slowly first, and then suddenly discharge. At this time, the current will corona all the fish around it, and the electric eel will take the opportunity to eat the fainted fish. The number of corona they can corona at one time is relatively large, far exceeding their food intake.

Electric eels generate electricity because of their special body structure. Their muscles belong to discharge bodies, their heads are negative electrodes, their tails are positive electrodes, and laminated batteries are formed in their bodies. When their bodies are excited by nerves, ions flow through cell membranes, thus connecting their discharges in series, and then releasing high voltage electricity of 600-800 volts. But different electric eels emit different currents. Like young electric eels, they don't emit too much current. In addition, after the parts on both sides of the electric eel that generate electricity are injured, their electricity will not be too great.
