Submarine hull shape and its construction is designed specifically to operate at deep ocean pressures. Specifically, spherical shapes are stronger under extreme pressure, and most submarines are constructed of flexible metals that allow them to contract and expand as the pressure changes.
Of course there's a limit as to how much pressure it can take, and that also is determined by the vessel's construction and design. For example, the Bathyscaphe Trieste has been to the bottom of the Challenger Deep in the Marianas Trench, the deepest point known in the ocean; her design is highly spherical and small to withstand such pressures. By comparison, a Russian ALFA, with a Titanium hull, is rated at 3,000 feet crush depth - but it can't maintain it for long, nor can it go to such depths that often because Titanium is a brittle metal when repeatedly exposed to high pressures.
they use very strong, thick materials or equilize the pressure on the inside to be the same as the outside
Submarine hulls are subject to sea pressure, and that pressure increases the deeper the submarine goes. There are design limits to the amount of pressure that a hull can take, and if that pressure is exceeded by diving too deep, the hull will fail and will be crushed.
Deep sea submarine tours are not currently available in this area.
how do deep sea bacteria survive
the nautilus was a submarine
Deep sea creatures have adapted to survive the immense pressure of the ocean depths through various biological mechanisms. Their bodies are often flexible and lack gas-filled spaces, allowing them to withstand the pressure. Some deep sea creatures also have specialized proteins and enzymes that help maintain their cellular structure under high pressure conditions. Additionally, their bodies may contain substances that act as pressure regulators, helping them to maintain internal balance. Overall, deep sea creatures have evolved unique adaptations that enable them to thrive in the extreme conditions of the deep ocean.

The deep sea has high water pressure due to the weight of the water above it. As you descend deeper, the pressure increases significantly. Conversely, the air pressure at deep sea depths is relatively constant and does not change as dramatically as water pressure.

It does not. It does not have predators in the deep sea.
No. While the suit might protect you from the pressure,it could not protect you from the extremely high temperatures.
