THE DEEP OCEAN | From Black Smokers To The Deepest Trenches | 4K

Far below the sunlit surface lies the largest living space on the planet, a world of cold, darkness and crushing weight. People have seen less than a thousandth of one percent of the deep seafloor, and yet it is full of life that has found its own way to survive without the sun. What feeds a world the sunlight never reaches, and how does a soft body live under kilometers of water? In this film you will see: 🔥 Hydrothermal vents, where chimneys pour black smoke into freezing water 🦐 Shrimp swarms, tube worms and mussels living on chemistry instead of light ❄️ Marine snow, the slow fall of food from the surface to the deep 🪼 Jellies, siphonophores and comb jellies built almost entirely from water 🌙 The nightly migration of billions of animals from the twilight zone 🐙 Dumbo octopuses, squid and a mother octopus who guarded her eggs for fifty-three months 🎣 Anglerfish and viperfish, hunters that wait in the dark with living light 🪸 Ancient coral gardens and glass sponges, and snailfish in the deepest trenches A calm journey from the hot springs of the seafloor to the bottom of the trenches, through eight worlds that follow their own rules for staying alive. 🎬 Filmed in stunning 4K, with relaxing music and calm narration. 🔔 Subscribe to Unknown Depths for more films about the places the map leaves blank. 💬 Which deep sea animal surprised you the most?
