The oceanic zone refers to the vast area of the ocean that lies beyond the continental shelf. This zone is characterized by deep waters, typically starting at a depth of about 200 meters. It is home to a diverse range of marine life, including species such as squid, whales, and deep-sea fish, which have adapted to the high-pressure environment. In the oceanic zone, sunlight penetrates only the upper layers, leading to distinct ecological zones. The deeper parts, known as the abyssal zone, are dark and cold, hosting unique organisms like bioluminescent creatures. This zone plays a crucial role in global climate regulation and carbon cycling.
