Oceans: The Deep Blue

The video explores the journey of marine animals as they dive to depths of 1000 meters in search of food. It describes the transition from the sunlight layer to the twilight zone, where sunlight fades and photosynthesis is impossible. Animals here are scarce and often transparent. As they reach 1000 meters, they enter the midnight zone, a realm of total darkness and high pressure. Creatures here have adapted with soft bodies and bioluminescence to survive. The video also highlights the nightly migration of millions of animals from the deep to feed, forming one of Earth's largest migrations.
