Journey to the abyss

The video explores the abyssopelagic zone, a deep ocean biome characterized by darkness and high pressure. It discusses the unique adaptations of organisms like brittle stars and tripod fish, and the ecosystem around hydrothermal vents where bacteria convert chemicals into food. The Mid Oceanic Ridge System, a significant underwater feature, is also highlighted. Despite its challenges, human exploration of the abyss is advancing with new technology.
