1. Abyssal zone

   The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. "Abyss" derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres (13,000 to 20,000 ft), this zone remains in perpetual darkness. It covers 83% of the total area of the ocean and 60% of Earth's surface. The abyssal zone has temperatures around 2 to 3 °C (36 to 37 °F) through the large majority of its mass. Due to there being no light, there are no plants producing oxygen, which instead primarily comes from ice that had melted long ago from the polar regions. The water along the seafloor of this zone is actually devoid of oxygen, resulting in a death trap for organisms unable to quickly return to the oxygen-enriched water above. This region also contains a much higher concentration of nutrient salts, like nitrogen, phosphorus, and silica, due to the large amount of dead organic material that drifts down from the above ocean zones and decomposes. The water pressure can reach up to 76 megapascal. The area below the abyssal zone is the sparsely inhabited hadal zone. The zone above is the bathyal zone.

1. abyssal zone

   The abyssal zone is a layer of the deep ocean that lies between 3,000 to 6,000 meters below the ocean's surface. This region experiences extreme conditions like very high pressure, low temperatures, and complete darkness, making it one of the harshest environments on Earth. Despite this, a variety of unique marine organisms have adapted to survive in this depth. It is the largest habitat for life on Earth, covering more than 50% of the planet's surface.

1. Abyssal zone

   The abyssal zone is the abyssopelagic layer or pelagic zone that contains the very deep benthic communities near the bottom of oceans. "Abyss" derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 meters, this zone remains in perpetual darkness and never receives daylight. It is the deeper part of the midnight zone which starts in the bathypelagic waters above. Its permanent inhabitants are able to withstand the immense pressures of the ocean depths, up to 76 megapascals. Many abyssal creatures have underslung jaws to sift through the sand to catch food. These regions are also characterized by continuous cold and lack of nutrients. The abyssal zone has temperatures around 2 °C to 3 °C through the large majority of its mass. The area below the abyssal zone is the sparsely inhabited Hadal zone. The zone above is the bathyal zone. These three zones belong to the deep-sea realm. Above on the continental platform there are respectively the euphotic and dysphotic zones. The abyssal zone lies partially in the dysphotic and partially in the aphotic zones.
