The three most common organisms at the bottom of the Mariana Trench are xenophyophores, amphipods and small sea cucumbers (holothurians), Gallo said. “These are some of the deepest holothurians ever observed, and they were relatively abundant,” Gallo said.

Is there anything below Mariana Trench?
With high pressure and darkness, the creatures are still alive and healthy. The Mariana Trench faces a scarcity of food, as the gorge is very far away from land. Therefore, reaching of the leaves or even of the trees to the bottom of the Trench is not possible.
What is inside of the Mariana Trench?
The Mariana Trench is the deepest point on Earth, void of light with the pressure of 48 jumbo jets. You’ll still find crustaceans, translucent snailfish, and sea cucumbers in it. The most surprising thing in the deep ocean is plastic. Visit Business Insider’s homepage for more stories.
What is deeper than Mariana Trench?
Tonga Trench
The deepest point in the Tonga trench, known as the Horizon Deep, is considered the second deepest point on Earth after the Challenger Deep and the deepest trench in the Southern Hemisphere.
What lives deepest in the ocean?
Meet the deepest fish in the ocean, a new species named the Mariana snailfish by an international team of researchers that discovered it. The Mariana snailfish (Pseudoliparis swirei) thrives at depths of up to about 8,000 meters (26,200 feet) along the Mariana Trench near Guam.
Is there a monster in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
Who owns Mariana Trench?
the United States
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources. Scientists use a variety of technologies to overcome the challenges of deep-sea exploration and explore the Trench.
Has a human reached the bottom of the ocean?
On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey, Don Walsh tells the BBC about their remarkable deep-sea feat.
Have we touched the bottom of the ocean?
The Challenger Deep is at the bottom of the Mariana Trench in the Pacific Ocean. It has only been reached once before, in 1960 by the explorers Don Walsh and Jacques Piccard. Mr Cameron said “My feeling was one of complete isolation from all of humanity,” he said.
Which ocean is coldest?
The Arctic Ocean

What is the scariest creature in the ocean?
The Scariest Monsters of the Deep Sea
- The Goblin Shark (Mitsukurina owstoni)
- The Proboscis Worm (Parborlasia corrugatus)
- Zombie Worms (Osedax roseus)
- Stonefish (Synanceia verrucosa)
- The Sloane’s viperfish (Chauliodus sloani)
- Giant isopods (Bathynomus giganteus)
- Frilled Shark (Chlamydoselachus anguineus)
How cold is the bottom of the ocean?
39°F
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
How cold is the Mariana Trench?
34-39 degrees F
At areas like the Mariana Trench (or the Marianas Trench; both spellings are commonly found) the water temperature ranges from 34-39 degrees F (1-4 degrees C).
What is the scariest creature in the Mariana Trench?
Featured as a scary creature in the film, the Black seadevil is just as terrifying in real life. Sharp teeth, gaping mouth and eyes exploding out of their sockets; this angler fish is known for its luminous antenna-like muscle protruding from its head. This light attracts its prey into close vicinity for an easy catch.
Are Megalodon still alive in the Mariana Trench?
‘No. It’s definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,’ notes Emma. ‘If an animal as big as megalodon still lived in the oceans we would know about it.’
What country is closest to the Mariana Trench?
The Mariana Trench is located in the western Pacific Ocean, east of the Philippines and about 120 miles east of the Mariana Islands. In 2009, President Bush declared the area surrounding Mariana Trench as a wildlife refuge, called the Marianas Trench Marine National Monument.
Why can’t we go to the bottom of the ocean?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.
How deep can a human go in the ocean before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
What is the deepest depth a human has gone?
35,853 feet
Vescovo’s trip to the Challenger Deep, at the southern end of the Pacific Ocean’s Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
Why did NASA stop searching the ocean?
This is largely because the vast majority of oceans remain unexplored. Thanks to a combination of impossibly deep waters, immense pressure, and a lack of sunlight, over 80 percent of the total oceans on Earth are a total mystery.
Is there a world under the sea?
Deep beneath the ocean floor off the Pacific Northwest coast, scientists have described the existence of a potentially vast realm of life, one almost completely disconnected from the world above.
