deepest-dwelling fish
have been found at roughly 27,000 feet However, fish aren’t the only creatures found at such incredible depths. Some whales, seals, and other cetaceans are able to dive to depths of nearly 10,000 feet.
Do deep sea fish explode when brought to the surface?
The correct answer is high pressure. A deep-sea, pressure is very high and fishes there involved to sustain. If the fish are brought to the surface too quickly, then the pressure cannot adjust fast enough and they literally explode as they are brought up.
What is the deepest fish ever found?

What has NASA found in the ocean?
To their amazement, the scientists discovered vibrant ecosystems around the vents, teeming with marine organisms, such as translucent snailfish and amphipods, tiny flea-like crustaceans , that had never been seen before. “With this discovery, we [came across] a whole new way of living on Earth,” says Shank.
How deep can humans go in the ocean?
That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
Are there fish in middle of ocean?
Deep water fish In the deep ocean, the waters extend far below the epipelagic zone and support very different types of pelagic fishes adapted to living in these deeper zones.
Is there life at the bottom of the Mariana Trench?
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.
How deep is the bottom of the ocean?
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
Has the bottom of the ocean been reached?
2019: Victor Vescovo reached a deeper part of Challenger Deep at 35,853 feet , breaking the record for the deepest dive in DSV Limiting Factor. His dive was part of the Five Deeps Expedition to reach the bottom of every ocean on Earth.
How do deep-sea fish not get crushed?
Under pressure Fish living closer to the surface of the ocean may have a swim bladder – that’s a large organ with air in it, which helps them float up or sink down in the water. Deep sea fish don’t have these air sacs in their bodies , which means they don’t get crushed.
Is there an ocean under the ocean?
Scientists discover an ocean 400 miles beneath our feet that could fill our oceans three times over After decades of theorizing and searching, scientists are reporting that they’ve finally found a massive reservoir of water in the Earth’s mantle, a reservoir so vast that could fill the Earth’s oceans three times over.
Who owns the ocean floor?
The oceans have no apparent surface features — just a flat, vast, briny expanse. They’re also all connected; the world’s five oceans are technically one single ocean that covers 71 percent of the planet [source: NOAA]. This makes it difficult to divide, and so ultimately, you own the oceans.
What’s deep down in the ocean?
In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep , the deepest point known on Earth.

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.
Are you crushed at the bottom of the ocean?
(The air would be compressed.) So, the lungs would collapse. At the same time, the pressure from the water would push water into the mouth, filling the lungs back up again with water instead of air. But if there’s no air-filled space to be pushed into, the body would not be crushed.
Can deep sea fish survive on the surface?
The extreme difference in pressure between the sea floor and the surface makes the creature’s survival on the surface near impossible ; this makes in-depth research difficult because most useful information can only be found while the creatures are alive.
Why do fishes eyes pop out when caught?
At depth, the gasses in the swim bladder are at equal pressure. When the fish is reeled up to the surface, the gasses expand and can cause the eyes to become bulged , cloudy or crystallized and the stomach to protrude out of the mouth.
Why do deep sea fish look weird?
Many animals in the deep sea are transparent, which helps them remain hidden from their predators Others are bright red. This works as excellent camouflage for these creatures, as most deep-sea animals cannot see the color red. Without red light, one cannot see the color red.
What will happen if deep sea fish are brought to a shallow?
The pressure inside would be as high as the pressure outside, so it wouldn’t be crushed. Deep sea fish keep the same pressure inside as they do outside. If you collected fish at the bottom of the ocean and brought them up quickly, they’d burst.
Is there a dragon fish?
