How do deep sea fish not get crushed by pressure?

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.
Scuba divers and free divers rely on equalising to prevent damaging their bodies. They compensate for static water pressure by adding equal gas pressure into their air spaces as the atmospheric pressure of the depth they are diving in. This prevents their air spaces from collapsing under pressure.
How can fish survive in deep ocean?
The chemical that allows fish to survive these depths is TMAO – trimethylamine N-oxide. The research shows that the amount of TMAO in ocean dwelling animals increases with the depth they live at.
The snailfish also had five copies of a gene called fmo3, which is crucial for the production of trimethylamine N-oxide (TMAO): a chemical that stabilises proteins and may protect them from becoming damaged by the intense pressure.

Can humans survive the pressure at the bottom of the ocean?
(2) There’s no air. You can’t breath at the bottom of the ocean. If you can’t breath, your body won’t stay alive for more than about 30 minutes. (Although you’d lose consciousness after about 5.)
Can humans survive down Mariana Trench?
The depth of the Mariana Trench makes it one of the deadliest places on the planet. Forever covered in darkness, water temperature is below 0 degree Celsius. What makes it near impossible for life as we know it to exist is the extreme water pressure. 8 tonnes per square inch increases with depth.
How do animals survive the pressure of the Mariana Trench?
Without gas-filled spaces like lungs or swim bladders, organisms in the great deep are less affected by pressure than we imagine. Some ocean species perform vertical migrations of 1,000 meters each day, experiencing a 100-atmosphere range of pressures with no harmful effects.
How do marine animals live under high pressure?
There is high pressure at the bottom of the sea. To balance out this pressure, the fishes and other sea animals have extra air dissolved in their blood. This internal fluid pressure balances the high pressure and animals are able to survive.
What metal can withstand the pressure of the Mariana Trench?
Titanium is the metal of choice for use in the ocean, as it is for all intents and purposes corrosion-free.
How strong is the pressure in the Mariana Trench?
While atmospheric pressure in the average home or office is 14.7 pounds per square inch (PSI), it is more than 16,000 PSI at the bottom of the Mariana Trench.
Can a submarine go to the bottom of the Mariana Trench?
The dive to the ocean’s deepest point turned up some surprises. The news: During a four-hour exploration of the Mariana Trench, retired naval officer Victor Vescovo piloted his submarine to 10,927 meters (35,849 feet) below the sea’s surface, making it the. He spent four hours at the bottom.
Has anyone touched the bottom of Mariana Trench?
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.
Is there anything deeper than the Mariana Trench?
Challenger Deep is the deepest point in the world ocean. Located within the already-deep Mariana Trench in the western Pacific Ocean, the actual deepness of Challenger Deep strains the imagination. We’ll take a look at some bizarre ways to consider this depth, but first we’ll explore why Challenger Deepis deep.
How deep has a human gone in the Mariana Trench?
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).
What is the weirdest thing found in the Mariana Trench?
How far down have we gone in the ocean?
Only three people have ever done that, and one was a U.S. Navy submariner. 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.
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.
What is under the ocean floor?
The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
How far can humans drill into the Earth?
Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.
Why did Russia stop drilling the Kola Superdeep Borehole?
Drilling was stopped in August 1994 at 8,578 metres (28,143 ft) of depth due to lack of funds and the well itself was mothballed. Because of higher-than-expected temperatures at this depth and location, 180 °C (356 °F) instead of the expected 100 °C (212 °F), drilling deeper was deemed unfeasible.
