ELI5: When lightning hits the ocean, why don't the fish die?
gpt
A lightning strike is quite a bit of energy when it's concentrated. When it hits the surface of the ocean, even though ocean water is a decent conductor, the electric current diffuses quickly in such a way that it's not lethal. An unlucky fish that is caught near the site of the strike may die, but a fish a few feet away would not.
