Hadal refers to the deepest regions of the ocean, specifically those found in oceanic trenches. These zones are typically deeper than 6,000 meters (19,685 feet). The hadal zone is characterized by extreme pressure, complete darkness, and very cold temperatures. Life here is scarce but highly specialized, with organisms adapted to these harsh conditions. Think of it like the ultimate extreme environment on Earth 🌍, even more challenging than the deepest caves.
