Electric eels use electricity to depart enemies. They can produce a shock of a maximum of 500 volts. Our bodies make use of electricity to communicate, including telling our hearts to keep beating.Electric eels are freshwater fishes that have the capability to stun their prey by generating electricity. On identifying prey, eels send a signal through the nervous system to the brain. The signals are passed using the electrolyte. Due to the sudden difference in electric potential, an electric current is generated just like a battery. Electric eels can control even the nervous system of the prey due to their electric abilities. This way they control the nervous system and muscles of the prey because of which they can prevent their prey from escaping.
