An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge , abyssal plains cover more than 50% of the Earth 's surface.
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 meters (9,800 ft) and 6,000 meters (20,000 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains are among the flattest, smoothest and least explored regions on Earth.

The bight is fairly shallow with the continental shelf extending far offshore except off south Florida and North Carolina. The Blake Plateau forms a zone of intermediary depth before dropping to the Hatteras Abyssal Plain with the Blake Escarpment. The Escarpment is defined as the geological bathymetric eastern boundary of the bight.
Before those orders could be carried out the flooding reached a point beyond recovery and on 6 October 1986 the K-219 sank to the bottom of the Hatteras Abyssal Plain [11] at a depth of about 6,000 m (18,000 ft). Britanov abandoned ship shortly before the sinking.
At the other end of the spectrum, benthos of the deep ocean includes the bottom levels of the oceanic abyssal zone. [7] For information on animals that live in the deeper areas of the oceans see aphotic zone. Generally, these include life forms that tolerate cool temperatures and low oxygen levels, but this depends on the depth of the water. [8]
Xenophyophorea / ˌ z ɛ n ə ˌ f aɪ ə ˈ f oʊ r iː ə / is a clade of foraminiferans.Xenophyophores are multinucleate unicellular organisms found on the ocean floor throughout the world's oceans, at depths of 500 to 10,600 metres (1,600 to 34,800 ft).
The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. The word abyss comes from the Greek word ἄβυσσος (ábussos), meaning "bottomless". [1] At depths of 4,000–6,000 m (13,000–20,000 ft), [2] this zone remains in perpetual darkness. [3] [4] It covers 83% of the total area of the ocean and 60% of Earth's ...
Also, scientists have discovered that the deeper these creatures live, the more gelatinous their flesh and more minimal their skeletal structure. These creatures have also eliminated all excess cavities that would collapse under the pressure, such as swim bladders. [11] Pressure is the greatest environmental factor acting on deep-sea organisms ...
