How can crabs, shrimp etc. live in deep sea when we barley have machinery that can handle it?

Question

I’m sorry in advance for poor format and english, I recently peaked an interest in the deep sea, and learnt how there are shrimp and crabs that are lower in depth than what we can send machinery, which is made of metal, and if i stand on a shrimp it crushes, but they can live at a depth where the pressure is 3000* my weight.

Answer 1

Our machines and people can’t stand high pressure because we have air sacs, our lungs.

Deep sea animals don’t have air sacs so they don’t have this problem
