how some fish species can live at insane depths of the ocean, while the best nuclear submarines can only go a couple thousand feet before being crushed.

Question

Soft bodied fish like the snail fish can apparently live at depths deeper than 25,000 feet… yet somehow, despite modern engineering marvels, and the availability of the strongest materials available to man, we can barely create underwater vehicles that dive to the same depths — and even the ones that do, are far from safe. How do these submarines get crushed and these soft bodied fish survive?

Answer 1

Because the internal pressure of those fish is similar to their environment.thats why the blob fish looks like that when you take them to the surface. They don’t look like when in the deep sea. They “explode” when you take them to the surface.

Submarines on the other hand need to be full of air because humans need to survive in the submarine. It’s essentially a giant hollow tube just begging to be crushed by the pressure.
