The Mesopelagic Zone is a layer of the ocean that extends from about 200 meters to 1,000 meters below the surface. This zone is often referred to as the "twilight zone" because it receives limited sunlight, making it dimly lit. It is home to a variety of marine life, including species like squid, lanternfish, and deep-sea jellyfish, which have adapted to the low-light conditions. In the Mesopelagic Zone, temperatures are cooler, and pressure increases with depth. This zone plays a crucial role in the ocean's ecosystem, as it serves as a transition area between the sunlit surface waters and the dark depths of the ocean. It is also significant for the global carbon cycle, as many organisms here contribute to the downward transport of organic material.
