Electricity-Generating Electric Eel

The electric eel can produce 600 volts of electricity to protect itself from enemies. Approximately half of the length of the electric eel’s body is made up of electric cells, and each electric cell has approximately 140 millivolts of charge. For example, if you lined up 4500 electric cells, you would be able to produce 630 volts of electricity. The electric cells are neatly arranged on the eel so the electricity flows in the same direction. The electricity flows from head to tail as if the electric eel’s head was the positive pole and its tail was the negative pole. When the eel sees its prey (such as a small fish), it stuns the fish with a weak electric current, and then eats the fish.

Electric eel’s capacity for electricity generation and dispersion can be used to develop new electric-supply devices. This could also be used to power personal medical devices that are implanted in the body.
