Electric organs of certain fish generate electricity using additive energy from stacked cells to generate a current.

“In certain fishes, however, we find electric organs, consisting of closely packed, orderly arranged groups of cells [electrocytes] whose only known function is the production of an electric field outside the body…The electric fields range from very weak to very strong (500 Volts or more). A typical electric organ of myogenic origin consists of several stacks of orderly arranged, flattened cells with each cell innervated separately by a spinal electromotor neuron. Because the whole organ is enclosed by a tight jacket of connective tissue, there are only little shunt currents, and the voltage differences generated by the individual electrocytes add up” (Kramer 1996:18-19).
