deep sea floor
Benthic zone below
The deep sea floor is the bottom of the ocean at its greatest depths, typically below 4,000 meters where sunlight never penetrates.
It's a cold, dark environment of immense pressure, home to hydrothermal vents, abyssal plains, and strange life forms adapted to extreme conditions.
Scientists study the deep sea floor for geological processes and unique ecosystems: Researchers discovered new species on the deep sea floor near volcanic vents.
