FOSA DE LAS MARIANAS | Criaturas Mortales a 11.000 Metros de Profundidad

The Mariana Trench is the deepest known point on Earth and one of the most extreme environments on the planet. Located in the western Pacific, it reaches depths of nearly 11,000 meters, where pressure exceeds 1,100 atmospheres, darkness is absolute, and temperatures barely rise above two degrees Celsius. Formed by the subduction of the Pacific Plate beneath the Mariana Plate, this gigantic geological scar has remained for millions of years a virtually isolated world, explored by very few human missions due to the enormous technical difficulties involved in reaching its depths. Despite conditions that for decades were considered incompatible with complex life, scientific expeditions have discovered a surprising diversity of organisms adapted to the abyss. Translucent fish, specialized crustaceans, extremophile microorganisms, and highly efficient predators have developed unique adaptations to withstand the extreme pressure, food scarcity, and total absence of sunlight. These ecosystems depend on energy sources very different from those found on the surface, including organic matter falling from upper layers and chemical processes associated with hydrothermal vents and deep sediments. Discoveries made in the trench have transformed the scientific understanding of the limits of life and evolution in extreme environments. Furthermore, research has revealed the presence of industrial pollutants and microplastics even at the deepest point in the ocean, demonstrating the global reach of human impact. The Mariana Trench remains one of Earth's last great unexplored frontiers, a place where each new expedition yields findings capable of challenging previous ideas about the biology, geology, and workings of our planet.
