Most people think that water is a conductor and that that is why it causes people to die from electrical shock when exposed to it. This is untrue.
My answer is two fold. First of all pure water is an insulator. When it is mixed with impurities those impurities are actually the conductors, not the water. Second electricity always takes the path of least resistance (It will travel through the material that is most conductive).
If your in a pool of water and the lightning strikes most of the charge won't travel through the water, because it is an insulater. It will travel through you the conductor. You are the path of least resistance (especially if your touching the bottom of the pool or the side of it). That is why people are killed in a pool from lightning strikes. Most of the people that survive such strikes were probably floating in the water, not touching anything else but the water (thus not completing a circuit).
I would suggest that most fish in the ocean do not get killed for this reason. Salt water is a very good conductor and as such the salt water pulls the path of the electricity from the lightning bolt around the fish, not through it. I would add this as another reason among the others above.
When someone is in a bath tub and an electrical item is drop in and that someone is electicuted, this is because the the path of least resistance is throught the person touching the bottom and sides of the tub. The water is mostly insulated from the current so it travels almost entirely through the human body.
because the electricity is dissipated.
Some fish can be electrocuted by lightning. It depends how close they are to the lightning strike. Natural waters usually have enough ions in it that the electric charge from lightning will be dispersed very quickly and so will not carry enough charge to electrocute fish if they are very far from the lightning strike.
You can but you shouldnt or else you will be fried fish if lightning strikes the water
No. The water conducts the current to earth and the fish are not harmed.
When lightning strikes the ocean, it doesn't really do anything. The only thing it pretty much does is just either stun the fish near the lightning strike or "fry" them. The things that only get affected by the lightning strikes are the people or animals near it.
If there close to the strike yes
Before a lightning strike, a charge builds up along the water's surface. When lightning strikes, most of electrical charge occurs near the water's surface. Most fish swim below the surface and are unaffected.
Not much really. A few unhappy creatures who are too close to lightning strikes may die, but that's about it.
Yeah, a plane will crash if lightning strikes it.
Lightning Strikes Again was created in 2007.
Everything Is vulnerable to damage from lightning strikes
If lightning strikes sand, glass is formed.
If it's real close, the fish can die. If it's further way, it's safe.
