electric eel , a fish without scales can download Amazonian strong shocks to knock a horse, has a system of electroshock strikingly similar to A Taser .
That’s the conclusion of a nine-month study on how the electric eel emits high voltage electric shock to locate and incapacitate prey. The research was conducted by Professor Kenneth Catania, of Vanderbilt University and published in Science.
Biologists have determined that an electric eel can generate about 600 volts electricity, almost triple plug in Europe.
So far, however, no one had studied how the system works electroshock eel. When he began observing the behavior of eels, Catania found that their movements are incredibly fast . They can strike and swallow a worm or a small fish in a split second. So Catania used a system of high-speed video, which ran a thousand frames per second , so that he could study the action of eels in slow motion.
Catania recorded three types different shock of eels: low voltage pulses to study their environment; short sequences of two or three millisecond pulses emitted while high voltage game; and high voltage discharges, high frequency pulses to capture prey or defend against attacks.
He found that the eel begins its attack with a salvo of high voltage pulses of high frequency of 10-15 milliseconds. In the high-speed video. This leaves immobilized prey in only three milliseconds. “It’s amazing. The eel can completely inactivate its prey in just three milliseconds . The fish are completely paralyzed,” Catania said.
The way in which occurs this download is very similar, although much faster than a Taser stun gun. “ A Taser 19 provides high voltage pulses per second, while the electric eel produces 400 pulses per second.”
The Taser works by paralyzing the nerves that control the muscles of the target , causing them to contract involuntarily. Catania determined to shake eels acted in motor neurons of the dam acted similarly.
