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 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 ...
The 45-day expedition to the Clarion-Clipperton Zone, which wrapped March 20, documented biodiversity in the abyssal plain. Using a remotely operated vehicle, the team on board the UK research ...
Scotoplanes live on deep ocean bottoms, specifically on the abyssal plain in the Atlantic, Pacific and Indian Oceans, typically at depths of over 1,200 to 5,000 meters (3,900 to 16,400 feet) [5] [6] Some related species can be found in the Antarctic.

Amperima rosea is a species of sea cucumber in the family Elpidiidae.It is found on the seabed at abyssal depths of 4,000 m (2.5 mi) or more. Around 1996, its numbers in the Porcupine Abyssal Plain in the northeastern Atlantic increased dramatically from a few individuals per hectare to over six thousand per hectare, a phenomenon that became known as the "Amperima event".
From the abyssal plain, the seabed slopes upward toward the continents and becomes, in order from deep to shallow, the continental rise, slope, and shelf. The depth within the seabed itself, such as the depth down through a sediment core, is known as the "depth below seafloor". The ecological environment of the seabed and the deepest waters are ...
