The Mariana Trench is the deepest part of the world's oceans, and the lowest elevation of the surface of the Earth's crust. It is almost 11 kilometers deep with pressure over 8 tons over square inch. In short, it is the most darkest and inhospitable place on Earth. You would think that no one could live there, yet some creatures managed to adapt! Some of them are beautiful and some are scary!
