The neritic zone is a coastal marine area that extends from the low tide mark to the edge of the continental shelf. This zone is characterized by shallow waters, typically less than 200 meters deep, and is rich in nutrients. The sunlight penetrates this area, allowing for photosynthesis, which supports a diverse range of marine life, including various species of fish, corals, and seaweeds. Due to its proximity to land, the neritic zone is often influenced by freshwater runoff from rivers and human activities. This makes it an important habitat for many commercially valuable species, such as shrimp and crabs, and serves as a breeding ground for many marine organisms.
