Los océanos: el fondo abisal

The video explores the abyssal zone, the deepest oceanic habitat, starting at 4000 meters deep. Despite its darkness and high pressure, life thrives here, including brittle fish and scavengers. The Mid-Atlantic Ridge, the largest mountain range, and hydrothermal vents are key geological features. These vents support unique ecosystems where bacteria convert gases into energy, sustaining species like the tuvine worm and pompejana alvinela. The Mariana Trench, the deepest part of the ocean, hosts scarce life forms like shrimp and jellyfish. The video highlights the mystery and discoveries of this vast underwater world.
