Meet the fish living 8,000 metres beneath sea level, on the depths of the ocean floor.
The deep sea was long considered devoid of life. Then in the last century, great advances in exploration proved that life existed even on the deepest spots of the ocean floor: the Mariana, Kermadec and New Hebrides Trenches around the Pacific Rim.
Scientific understanding of these extreme environments lags greatly behind that of the rest of the deep sea as a result of the technical challenges associated with such enormously high pressures. The last ten years has seen a renewed interest in exploring the ultra-deep sea, mostly prompted by new exploratory technologies.
From the technical challenges researchers face to the enigmatic habitats they explore, find out about the world beneath the waves, and meet the recently discovered fish living 8 kilometres deep. The remote and extreme ocean environments may not be as pristine as we once thought.
