The Sea Creatures That Shouldn't Exist at 36,000 Feet

They live where nothing should. At nearly 36,000 feet, almost seven miles down, the pressure reaches eight tons per square inch, the water sits just above freezing, and the darkness never ends. And yet the deepest place on Earth is crawling with life that breaks every rule of biology. In this video we descend into the hadal zone, the deepest 5% of the ocean, to meet the creatures that shouldn't exist: the record-breaking snailfish filmed over five miles down, the invisible wall no fish on Earth can cross, swarming amphipods that digest wood and coat themselves in metal, single-celled giants the size of your hand and what's really waiting at the very bottom of the Mariana Trench. How deep can life actually go? Let's find out.
