The ocean depths refer to the areas of the ocean that are far below the surface, typically starting at around 200 meters (656 feet) and extending to the ocean floor. This region is divided into different zones, including the bathyal, abyssal, and hadal zones, each characterized by unique environmental conditions, such as pressure, temperature, and light availability. Life in the ocean depths is adapted to extreme conditions, with many organisms relying on chemosynthesis rather than sunlight for energy. Notable creatures found in these depths include the giant squid, anglerfish, and various types of deep-sea jellyfish, showcasing the incredible diversity of life in this largely unexplored habitat.
