Question

When an ocean, lake, or pond gets struck by lightning, why don't all the fish die?

Answer 1

The energy is quickly dissipated across the surface of the water to the land (the earth) thereby not affecting sea or pond life...etc, as they are in the same situation as a bird sitting on a high voltage cable.

Answer 2

The current density will decrease as the cube of the distance

from the point of the strike.

The 'lethal zone` will therefore be relatively small.

The 'stun zone' will be larger, but a lot of the animals in

it will recover and go on about their business.
