The bathypelagic zone, also known as the midnight zone, is a layer of the ocean that extends from about 1,000 to 4,000 meters (3,280 to 13,123 feet) below the surface. This zone is characterized by complete darkness, as sunlight cannot penetrate this deep. The water pressure is extremely high, and temperatures are typically just above freezing. Life in the bathypelagic zone is adapted to these harsh conditions. Organisms such as deep-sea fish, squid, and bioluminescent creatures thrive here, often relying on bioluminescence for communication and attracting prey. The bathypelagic zone plays a crucial role in the ocean's ecosystem, contributing to nutrient cycling and carbon storage.
