The zone that is almost totally dark is known as the aphotic zone. This layer of the ocean, typically found at depths greater than 200 meters (about 656 feet), receives little to no sunlight, preventing photosynthesis. As a result, it is home to organisms adapted to extreme conditions, such as bioluminescent creatures and various deep-sea species. The absence of light creates a unique ecosystem that relies on organic matter falling from the upper layers of the ocean for sustenance.
