The aphotic zone refers to the deep, lightless layer of the ocean where sunlight cannot penetrate. It typically starts around 200 meters (656 feet) deep and extends to the ocean floor, which can be thousands of meters deep depending on the location. The exact depth of the aphotic zone can vary based on factors such as water clarity and geographic location.
