If you are one of those who love to bathe in rivers, seas or lakes, and spend long seasons in spas, at some point you must have heard the command to leave the water at the beginning of a thunderstorm, and you will have ended up bored, watching the storm from a place Protected, and perhaps wondering why fish are not electrocuted. Here are some possible answers.

One of the most amazing things you can live in is to watch a thunderstorm near a large water surface, a beach at sea, a lake or a large river, and you must have heard about cases of bathers who were struck by lightning While they were in the water.

Do not? So here goes one: during the summer of 2014 a lightning bolt fell into the sea on a California beach, causing one death and at least ten wounded. But nevertheless,

He did not die no fish . What are the reasons why fish are not electrocuted?


One possible answer is NASA, which has conducted studies on the electrical discharges monitored throughout the planet through meteorological satellites. A study in 2002 on the overall frequency and distribution of observed from space rays, found that nearly half million electrical discharges that occur annually, only 10% occurs in water surfaces, ie, that only one in ten rays fall into the sea .


Lightning causes more than a thousand deaths a year worldwide , and naturally so, if we consider the extraordinary power of this phenomenon: a normal discharge may be 300 million volts and 30,000 amps, enough to kill a person ; Then why do not we see dead fish after a thunderstorm with lightning falling on a lake, or in the sea? 3

This could be the explanation: the fish would be safe because they remain under water, to a depth where the power of lightning does not reach them. Some studies have found that electrical shocks, thanks to water conductivity, are distributed horizontally rather than vertically , so that a fish could only be affected if any part of his body was found outside the water, as happens with swimmers humans.

Giles Sparrow, author of Physics in Minutes, says that one way to protect yourself during a lightning storm, if you surprises in the water, would act as fish and dive, but could be a little as practical: “If you remain in the Water you should try to submerge yourself, although it is unlikely that anyone can hold their breath long enough to avoid the danger. ”

Fish instead yes, they can stay long under water, not holding my breath, and that is why most of the fish are not electrocuted when lightning strikes in the water . 4
