Explorers are in awe at the discovery of new species and geologic events at extreme depths along the Marianas trench. At these depths marine life must survive in extreme conditions with very little oxygen, food , no sunlight and extremely cold conditions under extreme pressure. With all of that said, most of the bio-mass of the planet live at these depths of more than 200 meters deep.
Watch this full documentary video of thriving marine life in the extreme environments at thousands of feet below the surface.
