There are sea creatures who live over a mile underwater. How do they not get crushed from the water pressure, considering it takes specially designed titanium submersibles to endure that kind of pressure.

have u ever tried to squash a flee? it doesnt work.
comparably, the size of a fish relative to the sea is very small.

Wow, quite a range of theories there..... Anyway the reason is because submarines try to keep their internal pressure equal to surface pressure ie. 14.7 psi. So the deeper the sub goes the greater the external pressure until it finally collapses. Fish however don't try to maintain a pressure difference. The pressures inside them are equal to their surrounding environment. The fish do have dissolved gas in their tissues and this will come out of solution and kill them if they are raised to the surface to quickly just like a diver getting the bends.

It's because of relative difference between internal and external pressure. The submarine has to maintain an internal pressure suitable for the occupants. At a great enough depth, that can't help but be crushed by the external pressure.
If you did this in reverse, and raised one of those sea critters to surface level, it would probably explode, because its own internal pressure would be greater than the external pressure.

Whats interesting is they still don't know what else exists down there. Most of the deep sea fish hang around under water vents or volcanoes or plates in the Earth where they get air and heat. The pressure wouldn't be so heavy near them.

i think it has to do with boyle's law as the fish are already in the water and they have air in them the pressure is constant it never changes yet when you have air in your body as you move deeper into the ocean the air compresses or get smaller and the pressure in the submarine and in the people have to equalize when the pressure is not equalized properly it implodes or explodes the submarine ...when you come back up from being deep in the ocean the air in the submarine and in your body expands and the pressure inside the sub and your body have to adjust and make times ascents or they will explode

All the answers relating to pressure and wow boyle's law all make sense. I love the flea answer too. All to do with physics, and very correct.
Another answer is the bio structure of the creatures that live underneath.
They dont have our type of bones - fish bones especially deep living creatures have very flexible bones to deal with the pressure. See that answers pressure and physics too

They have been born there, so have been their father and mom and the determine's father and mom and so on even previously the dinosaurs. they have gotten used to the tension and temperatures, in the event that they got here to the floor they could maximum probably die directly because of the fact the tension adjustments drasticly and so does the temperature. something is achieveable. as an occasion. in case you place your hand in chilly water, and then start to warmth the water.. you will no longer experience any adjustments because of the fact which you have gotten used to the warmth because it will enhance. yet then, in case you place your hand directly into warm water, you will experience the burn and pull your hand out. those creatures have been given used to the tension and temperatures so as that they've have been given no undertaking with it. the backside of the sea and the precise under the water is carefully distinctive in lots of approaches - so as that they'd not survive up right here. it rather is why their shapes threat (because of tension and temperatures). human beings look distinctive in Germany than they do in China, because of the temperatures and climatic situations. human beings look distinctive in Russia then they do in u.s. - because of the climate. they have gotten used to it, and their bodies evolve to get used to it :) desire this helped, cya!

You have to remeber that is where they live. When they are brought to the surface, they die as we do at those depths. They are specially designed with bladders etc that can help them cope with the depth. Even people can adapt to depths slowly (not too deep, though) which is why they have decompression chambers for those spending long times down below.

The air in the submarine is what gets crushed. Fish have to air in them. (Or microscopic amounts).

I wonder that too.
Like why don't thier eyeballs and intestines come shooting out, like a humans would.
