ELI5: If humans cannot reach the ocean floor without being crushed by the pressure of the water above them, how do bottom feeders and other deep sea creatures manage to survive down there?

I saw a picture recently of a really fleshy looking bottom feeder, which prompted this question. 

Also, I should add that when I say humans I am also including any technology such as subs, suits, and stuff like that.

Humans have a small problem, they need air (a gas) to breathe. Lungs are large, relatively open space in the chest cavity, and they tend to get crushed under pressure. Same problem with subs.

Organisms that live at that depth have their entire internal body at the same pressure. They don't have hollow spaces. Since the pressure is equalized there is no crushing force.
