If humans can't go to the bottom of the ocean due to pressure, how do sea creatures that live down that deep withstand all of that pressure?

These animals have evolved to survive the extreme pressure of the sub-photic zones. The pressure increases by about one bar every ten meters. To cope with the pressure, many fish are rather small. These creatures have also eliminated all excess cavities that would collapse under the pressure, such as swim bladders.
