this could be the aphotic zone where only 1% of the surface light reaches. The Bethnic zone is the VERY bottom and is basically the sediment zone.
The permanently dark zone below the photic zone is called the aphotic zone. In this region, sunlight is unable to penetrate deep enough for photosynthesis to occur, resulting in a lack of primary production by plants. Organisms in this zone rely on alternative energy sources, such as detritus and chemosynthesis.
aphotic zone
The upper 100 -200 m of the ocean is called the Photic zone (photo = light).At about 150 meters 99% of light is absorbed.Beyond the Photic zone, light does not penetrate, and it is pitch dark.
photic and aphotic derive their names fron the root word photo means light that is photic and aphotic zone differ each other in amount of light reaching there photic zone is directly lit up by by solar energy while aphotic zone is perpetually dark inhabiting least amount of floran fauna

It is called dark zone
The layer that is permanently devoid of light is the abyssal zone, which lies beneath the photic zone of the ocean, typically at depths greater than 1,000 meters (3,280 feet). In this dark region, no sunlight penetrates, resulting in extreme conditions with high pressure and low temperatures. The abyssal zone is home to unique organisms that have adapted to survive without light, relying on chemosynthesis or scavenging.
Aphotic zone is the area of a lake or an ocean which gets little or no sunshine throughout the year.
