Over the course of millions of years, a single animal has divided into more than 200 different species.
Perhaps the most dynamic change in the evolution of the fish is the development of an electric organ. Located at the bridge between the fish’s tail, and body, the electrical organ produces a small amount of electrical discharge known as an Electric Organ Discharge (EOD). Elephant fish “see” by way of this discharge, known as electro-location. Electro-location works similarly to a bats echolocation. The electric organ can emit an extremely low voltage, generating a small electrical field that surrounding the fish. Elephant fish are always emitting pulses into their environment electrically.
