Why We Can't Bring Anything Back From The Deep Ocean Alive

You can't bring anything back from the deep ocean alive. And it's not what you think. You're not just pulling a fish up. You're making it explode from the inside out. At 4km deep, pressure is 400x what we feel on land. Bring it up, gases in its blood expand, organs rupture, proteins collapse. Even if it survives that, the warmth and light of our world will kill it. The deep sea keeps what belongs to it.
