The mesopelagic zone, also known as the twilight zone, is a layer of the ocean that extends from about 200 meters (656 feet) to 1,000 meters (3,280 feet) below the surface. This zone is characterized by decreasing light levels, with only a small amount of sunlight penetrating it, which leads to a dimly lit environment.
