Fish have swim bladders. these bladders allow for a fish to rise and fall in the water. Salt as well keeps fish from "exploading" in deep water as well as their skellitons.
Many fisher men have this problem when bringing the larger groupers up from deep water. There are very few fish that can be pulled directly out of deep water one of them being a salmon the other fresh water is a trout without exploading the swim bladder. Just like humans, fish need to adjust for pressure by inflating and deflating their swim bladders.
If a fish is pulled from the deep too quickly, chances are his
stomach will be protruding from its mouth, First, it's not the stomach that's the problem, it's that the fish's air bladder has ruptured internally and released air into the fish's body cavity. This trapped air expands so much that it displaces the other organs.

Their skeleton, muscles, and skin was made for that environment. Humans were made to withstand the tremendous pressure of the atmosphere. It's just how things are made.

They can withstand pressure because they don't have any air spaces in them. They don't have swim bladders, like most shallow water species have.

We are made to withstand the pressure of the environment, are fins have a texture protection to protect our muscle skeleton, just like skin protects your skeleton.

They are designed by Mother Nature to live in that environment, one we could not comfortably live in
