Oceans: The Abyss

The video explores the abyssopelagic zone, a deep ocean habitat starting 4000 meters down. Despite its harsh conditions, life thrives here, including brittle stars and tripod fish. The abyss hosts the largest mountain range, mid-ocean ranges, and hydrothermal vents that support unique ecosystems. The Mariana Trench, part of the Hadel zone, is the deepest ocean habitat. Few have explored these depths, but each dive reveals new discoveries.
