The deepest zone of the ocean, the hadalpelagic zone extends from 19,700 feet (6,000 meters) to the very bottom at 36,070 feet (10,994 meters) in the Mariana Trench off the coast of Japan. The Epipelagic Zone is the most explored zone in the ocean. [4][5] The term "hadal" was first proposed in 1956 by Anton Frederik Bruun to describe the parts of the ocean deeper than 6,000 m (20,000 ft), leaving abyssal for the parts at 4,000–6,000 m (13,000–20,000 ft). It is the pitch-black bottom layer of the ocean. The water temperature is constantly near freezing and only a few creatures can be found at these crushing depths.
[8], The only known primary producers in the hadal zone are certain bacteria that are able to metabolize hydrogen and methane released by rock and seawater reactions (serpentinization),[17] or hydrogen sulfide released from cold seeps. They also have a well developed sense of smell. The weight of all the water over head in the Mariana Trench is over 8 tons per square inch.

These zones determine the depth. The temperature is constant at just above freezing.
[15][16] Some invertebrates do occur deeper, such as certain Astrorhizana foraminifera, polynoid worms, myriotrochid sea cucumbers, turrid snails and pardaliscid amphipods in excess of 10,000 m (33,000 ft).
It contains all of the coral reefs and kelp forests on Earth. The Hadalpelagic zone is the deepest of the deep sea's layers. The second zone is the Photic or Euphotic Zone. It goes from 1000m to 4000m depth. Trench communities do, nevertheless, display a contrasting degree of intra-trench endemism and inter-trench similarities at a higher taxonomic level.
Sediments of the deep sea primarily originate from a rain of dead marine organisms and their wastes. HROV Nereus was thought to have imploded at a depth of 9,990 meters while exploring the Kermadec Trench in 2014. The hadal zone is the deepest region in the ocean, extending from 6,000 meters to 11,000 meters below the surface. The low nutrient level, extreme pressure and lack of sunlight create hostile living conditions in which few species are able to exist.
Even at the very bottom life exists.
Some typical animals you could find here are Swordfish, squids, Wolf Eels, Cuttlefish and other semi-deepsea creatures.
Many Abyssal creatures have unhung jaws so that they can sift through the sand on the bottom.
This is because it is on the top of the ocean. The Aphotic Zone and the Photic Zone. Unmanned robotic submersibles may be remotely operated (connected to the research vessel by a cable) or autonomous (freely moving). They swallow up other fish and crustaceans, moving slowing along the ocean floor to conserve energy as they hunt.
Amphipods are soft-shelled crustaceans resembling large fleas. It starts at the surface of the ocean and ends at the point where there isn't sufficient sunlight to preform Photosynthesis. It is part of the Oceanic Zone.
Because no light reaches this part of the ocean, it is impossible for plants to thrive but there are still hardy creatures that call these depths home. Entdecken Sie Hadalpelagic Zone von Cyntrix bei Amazon Music. (This point is determined by the clarity of the water, but is typically around the beginning to middle of the Mesopelagic Zone.)
Found in both the Kermadec and Japan trenches, decapods were spotted actively hunting amphipods.
Benthescymus crenatus was the most well represented species at this point in the hadal zone. All rights reserved. Creatures to be found here are often less beautiful and possibly even grotesque looking like the Fang-tooth below.
Introduction.
The Hadalpelagic Zone The Rat tail fish also known as Grenadiers are slender scavengers that feed on crustaceans and smaller fish when they can.
[6] The name refers to Hades, the ancient Greek god of the underworld.
The Abyssopelagic Zone (or abyssal zone) extends from 13,100 feet (4,000 meters) to 19,700 feet (6,000 meters).
Other species to be found though, are: Squid, large whales and octopusses, but this zone is difficult for fish to live in. The very deepest part of the ocean is the Mariana Trench. As no sunlight reaches this layer of the ocean, deep sea creatures have reduced eyesight, with very large eyes for receiving only bioluminescent flashes.
The deepest zone of the ocean, the hadalpelagic zone extends from 19,700 feet (6,000 meters) to the very bottom at 36,070 feet (10,994 meters) in the Mariana Trench off the coast of Japan.
It is believed that most life at this depth is sustained by marine snow or the chemical reactions around thermal vents. It's deepest point is 11,000m. National Oceanic and Atmospheric Administration
[3] Most hadal habitat is found in the Pacific Ocean. It was found at 7,000 meters. [6], Depths in excess of 6,000 m (20,000 ft) are generally in ocean trenches, but there are also trenches at shallower depths.
