How do fish not get crushed by pressure?
Under pressure
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.
What happens if fish dive too deep?

Can you bring deep sea creatures to the surface?
Several studies indicate the deep-sea organisms can withstand a wide range of pressures.
We frequently capture organisms at depth and bring them to surface alive, as long as we can keep them cool

Yes, this fish — and its teeth — are real.
Why do deep-sea creatures go to the surface?

Gas is compressed under high pressure and expands under low pressure
. Because of this, these organisms have been known to blow up if they come to the surface.
How do anglerfish mate?
It's hard to find a partner in the dark depths, so
a tiny male anglerfish fuses its tissues to a more massive female during mating

Most jellyfish bioluminescence is used for defense against predators. Jellyfish such as comb jellies
produce bright flashes to startle a predator
