What happens when deep sea fish reach low pressure waters?

Question

I heard that they flip inside out. Is that true and if so, why?

Answer 1

Occasionally, when you pull a fish up quickly from the depths, its air bladder will expand. The air bladder works like ballast in a hot air balloon, and it expands and contracts to help the fish remain at the depth it's living at. I've never heard of a fish turning inside out,  but they look like they're really bloated when this happens.  

Answer 2

I've never heard of that.

Answer 3

They don't actually flip inside out. Their eyes will pop out of the sockets and their swim bladder will pop out of their mouths. They're usually  immobilized or even killed on their way up to the surface.

Answer 4

If you pull one up from to deep to fast it will make his eyes bug out. They cant swim away because the swim bladder cant adjust that fast so you have to poke a needle in them to let the air that expanded out of the bladder and then the will be ok. I am sure that if the fish was really really deep and you pulled it up really fast that it butt would prolapse and it would die.
