Early fisherman used to send horses out as bait and once they were then exhausted from using all their juice on the horses, they would grab them and merrily be on their way.
While the horses were in the water, the fisherman would notice that the eels would jump out of the water to shock their prey, although there was no recorded evidence as such. Well, until now that is. Researchers learned that electric eels not only leap towards their prey, they increase their voltage significantly while doing so, from about 10 to 300 volts. As the eel jumps there is less resistance from the water transferring the charge directly in to its prey. We advise standing well away from the water.
