Mark me as brainliest
Explanation:
Fish living closer to the surface of the ocean may have a swim bladder – that's a large organ with air in it, which helps them float up or sink down in the water. Deep sea fish don't have these air sacs in their bodies, which means they don't get crushed.

Explanation:
The deep sea is a very difficult place to live. There is no light, it’s cold, there’s not much oxygen and little food – and, as you rightly point out, the creatures that live there have to deal with the enormous pressure of the water above.
In the deepest part of the Atlantic, the pressure can be 840 bars – that’s about 840 times the pressure we experience at sea level. At Challenger Deep in the Mariana Trench – the very deepest part of all the world’s oceans – the pressure may be 1,000 bars or more.
But the creatures that live in the deepest parts of the ocean have special features, which help them deal with these tough conditions – including the crushing pressure.
Under pressure
When you dive to the bottom of a deep swimming pool, you might start getting a painful or unpleasant feeling in your ears and sinuses. This is because they contain air: that feeling comes from the air sacs in your body being squashed by the pressure of the water.

The deepest dwelling species of fish, called the hadal snailfish, can be found at depths of about 8,200m.
