The World Beneath the Ocean We Barely Know | Mysteries of the Deep

Beneath the surface of our oceans lies an enormous world that sunlight never reaches. Descend with us into the deep sea—past the familiar blue waters and into a realm of crushing pressure, permanent darkness, glowing creatures, hydrothermal vents, and ecosystems unlike almost anything we encounter on land. How does life survive thousands of metres beneath the surface? Why do so many deep-sea creatures produce their own light? What exists around hydrothermal vents without sunlight? And how much of this hidden world do we truly understand? From bioluminescent animals and anglerfish to black smokers, chemosynthesis, ocean trenches, and the unexplored seafloor, this episode of Worlds Unseen explores one of the strangest environments on our own planet. We often look toward distant planets when searching for alien worlds. But one of Earth’s greatest unknown worlds has been beneath us all along.
