You must have heard of fish like 'Electric eel' and 'Catfish'. These fish use lightning shock to trap their prey. Perhaps you wonder how the fish can cause a current shock, but it is true that fish called electric catfish and electric eels use electric high voltage shock to kill their prey. The current or electric shock produced by the fish occurs in the cells present inside its body, which are called electrolytes. When an electrolyte is excited, ions present on the outer surface of the cell start moving rapidly, producing electricity. For example, electric catfish can kill their prey with an electric shock of about 300 to 350 watts. This fish hunts mainly at night and found in the Nile river. Similarly, a fish called electric eel can produce an electric shock of up to 600 watts to kill its prey, It is enough to lead the hunting of up to a horse.
