Secrets of the Mariana Trench. Mariana Trench on the world map

The Mariana Trench is considered the most deep place on the earth's surface . Since the ocean, compared to land, has not been studied well enough, this zone hides a lot mystical riddles. And the monsters living in it are a favorite topic for discussion and reasoning.

Location of the Mariana Trench

The Mariana Trench is a crescent-shaped trench. It is located in the Pacific Ocean. Own The basin was named after the nearby Mariana Islands.. The length is about 2550 km, and the width is about 70 km.

However, the ocean diligently hides its real parameters. It is known that it has a V-shape. One of the main puzzles is its depth. Modern appliances show a mark of 10994 m with an error of 40 km.

Attention! The deepest mark is called the "Challenger Abyss" and is located 340 km from the island of Guam.

Chute diving

The study of the place is carried out with the help of deep-sea vehicles. So, in 1960, Jacques Picard and Don Walsh went down to the bottom on the Trieste bathyscaphe. For 8 hours, the installation rose back to the surface. After inspection, damage to the skin and lifting cables was found.


Submersions of vehicles were made in 1995 by the Japanese, also in 1996. Americans. The steel structure was dented by sea monsters.

Later, the German bathyscaphe "Highfish" with three researchers on board sank already 7 km. At the same time, scientists have recorded the appearance of strange creatures.

Important! Thanks to hydrothermal springs, general temperature water in the abyss warms up to +4 degrees.

The Daikoku volcano was recorded in the Mariana Trench, where the crater is 187 degrees. Its analogue is found only on the satellite of Jupiter (Io).

History of transparent fish

In 1948, lobster hunters from Australia told unusual story about a transparent fish. Its length is at least 30 m. According to the stories of fishermen, outwardly it is very similar to a shark that lived in ancient times.

The monster had a mouth about two meters. Teeth up to 10 cm in size have been found on the ocean floor. This gave rise to speculation that, perhaps, terrible predators live at a depth.

Encounter with monsters

Scientists are still not able to identify objects living at the very bottom of the gutter. During the dive, many photographs were taken showing strange and frightening creatures.


it one and a half meter worms without a mouth, mutated octopuses and giant starfish.


Toxins and radiation

British experts published an interesting document, according to which body marine life soaked through with toxic substances.


They recorded a level of pollution much higher than that which was filmed from animals living in coastal waters. Furthermore, some species even emitted radiation.


Reference! The bottom of the cavity is covered with mucus. Here, mainly, particles of shells and ancient plankton. Due to the pressure of the water, everything turns into fine thick mud.

Prehistoric megalodons are alive

Assumed scientific world one of giant sharks prehistoric period - megalodon disappeared millions of years ago. In 1997, Japanese experts made a frightening video. They designed a feeder to which they lured a creature a couple of tens of meters long. This proved the fact that megalodons are still alive.

Various sea animals

Important! On May 31, 2009, the Nereus apparatus was submerged, it measured the depth of the depression - 10,902 m below sea level. Were received unique photos inhabitants of the depths.


The gutter has become a habitat massive unicellular amoeba. Their sizes reach up to 10 cm. Moreover, they can easily exist next to uranium, lead and mercury. And from such a neighborhood, they only feel better. Everything living and non-living is brought together here.


The Mariana Trench is fraught with many secrets that are not subject to full study even with modern equipment. Paradoxically, even at such an impressive depth, life has been discovered.

All of us in childhood read many legends about incredible sea ​​monsters ah, inhabiting the ocean floor, always knowing that these are just fairy tales. But we were wrong! These incredible creatures can be found even today if you dive to the bottom of the Mariana Trench, the deepest place on Earth. What hides the Mariana Trench and who are its mysterious inhabitants - read in our article.

The deepest place on the planet is the Mariana Trench or Mariana Trench- located in the western part Pacific Ocean near Guam, east of the Mariana Islands, from which its name came. In its shape, the trench resembles a crescent moon, about 2550 km long and 69 km wide on average.

According to the latest data, the depth Mariana Trench is 10,994 meters ± 40 meters, which even exceeds the highest point on the planet - Everest (8,848 meters). So this mountain could well be placed at the bottom of the depression, moreover, about 2,000 meters of water would still remain above the top of the mountain. The pressure at the bottom of the Mariana Trench reaches 108.6 MPa - more than 1,100 times the normal atmospheric pressure.

A man only twice sank to the bottom Mariana Trench. The first dive was made on January 23, 1960 by US Navy Lieutenant Don Walsh and explorer Jacques Picard in the Trieste submersible. They stayed at the bottom for only 12 minutes, but even during this time they managed to meet flat fish, although according to all possible assumptions, life at such a depth should have been absent.

The second human dive was made on March 26, 2012. The third person who touched the mysteries Mariana Trench, became a film director James Cameron. He dived on the single-seat Deepsea Challenger and spent enough time there to take samples, take pictures and film in 3D. Later, the footage he shot formed the basis documentary film for the National Geographic Channel.

Due to the strong pressure, the bottom of the depression is covered not with ordinary sand, but with viscous mucus. For many years, the remains of plankton and crushed shells accumulated there, which formed the bottom. And again, due to pressure, almost everything is at the bottom Mariana Trench turns into fine greyish-yellow thick mud.

Sunlight has never reached the bottom of the depression, and we expect the water there to be icy. But its temperature varies from 1 to 4 degrees Celsius. AT Mariana Trench at a depth of about 1.6 km are the so-called "black smokers", hydrothermal vents that shoot water up to 450 degrees Celsius.

Thanks to this water Mariana Trench life is sustained as it is rich in minerals. By the way, despite the fact that the temperature is much higher than the boiling point, water does not boil due to very strong pressure.

Approximately at a depth of 414 meters is the Daikoku volcano, which is the source of one of the rarest phenomena on the planet - a lake of pure molten sulfur. AT solar system this phenomenon can only be found on Io, a moon of Jupiter. So, in this "cauldron" the seething black emulsion boils at 187 degrees Celsius. So far, scientists have not been able to study it in detail, but if in the future they can advance in their research, they may be able to explain how life appeared on Earth.

But the most interesting thing in Mariana Trench are its inhabitants. After it was determined that there was life in the basin, many expected to find incredible sea monsters there. For the first time, the expedition of the research vessel "Glomar Challenger" encountered something unidentified. They lowered into the cavity a device, the so-called "hedgehog" with a diameter of about 9 m, made in the NASA laboratory from beams of ultra-strong titanium-cobalt steel.

Some time after the start of the descent of the apparatus, the sound-recording device began to transmit some kind of metallic rattle to the surface, reminiscent of the gnashing of saw teeth on metal. And vague shadows appeared on the monitors, resembling dragons with several heads and tails. Soon, scientists became worried that the valuable device could forever remain in the depths of the Mariana Trench and decided to take it aboard the ship. But when they pulled the hedgehog out of the water, their surprise only intensified: the strongest steel beams of the structure were deformed, and the 20-centimeter steel cable on which it was lowered into the water was half sawn.

However, perhaps this story was too embellished by the newspapermen, since later researchers discovered very unusual creatures there, but not dragons.

Xenophyophores - giant, 10-centimeter amoeba that live at the very bottom Mariana Trench. Most likely due to strong pressure, lack of light and relatively low temperatures these amoebas have acquired enormous dimensions for their species. But in addition to their impressive size, these creatures are also resistant to many chemical elements and substances, including uranium, mercury and lead, which are lethal to other living organisms.

Pressure in M Arian Trench turns glass and wood into powder, so only creatures without bones or shells can live here. But in 2012, scientists discovered a mollusk. How he retained his shell is still not known. In addition, hydrothermal springs emit hydrogen sulfide, which is deadly to shellfish. However, they learned to bind the sulfur compound into a safe protein, which allowed the population of these mollusks to survive.

And that is not all. Below you can see some of the inhabitants Mariana Trench, which scientists have been able to capture.

Mariana Trench and its inhabitants

While our eyes are directed to the sky to the unsolved mysteries of space, our planet remains unsolved mystery- ocean. To date, only 5% of the world's oceans and secrets have been studied Mariana Trench this is only a small part of the secrets that are hidden under the water column.

The Mariana Trench is a crescent-shaped trench in the western Pacific Ocean, east of the Mariana Islands near Guam. The region surrounding the trench is notable for many unique natural conditions. The Mariana Trench contains the deepest known points on Earth, vents seething with liquid sulfur and carbon dioxide, active mud volcanoes and marine life, adapted to pressures 1000 times greater than at sea level.

The Challenger Deep, in the southern part of the Mariana Trench, is the deepest place in the ocean. Its depth is difficult to measure from the surface.

In 2010, the depth of the Challenger Deep was indicated at 10,994 m (36,070 ft), measured by sound pulses sent across the ocean during a 2010 survey. National Management Oceanic and Atmospheric (NOAA).

In 2012, filmmaker and explorer James Cameron sank to the bottom of the Challenger Deep, reaching 10,898 meters during the 2012 expedition. But he could have gone a little deeper. Cartographic survey of the seabed with high resolution, published in 2014 by researchers at the University of New Hampshire, showed that the bottom of the Challenger Deep was at a depth of 36,037 feet (10,984 m).

The second deepest place in the ocean is also located in the Mariana Trench. The depth of the siren (Sirena Deep), which lies 200 km east of the Challenger Deep, is 10,809 m.

For comparison, Mount Everest stands at 8,848 meters above sea level, which means that the deepest part of the Mariana Trench is 2,147 meters deeper than Mount Everest.

Where is the Mariana Trench

The Mariana Trench is 2,542 kilometers long, more than five times the length Grand Canyon. However, the trough averages 69 km wide.

Because Guam is a US territory and the 15 Northern Mariana Islands are a US commonwealth, the United States has jurisdiction over the Mariana Trench. In 2009, President George W. Bush established the Mariana Marine National Monument, which created a protected marine reserve covering about 506,000 square kilometers of seabed and waters surrounding the outlying islands. It includes most Mariana Trench, 21 underwater volcanoes and areas around three islands.

How was the Mariana Trench formed?

The Mariana Trench was created as a result of a process occurring in a subduction zone where two massive plates of oceanic crust collide. In the subduction zone, one piece of oceanic crust is pushed and pulled under another, sinking into the Earth's mantle, the layer beneath the crust. Where two pieces of bark intersect, a deep trough forms over a bend in the sinking bark. In this case, the Pacific Ocean's crust bends below the Philippine crust.

The Pacific crust, also called the tectonic plate, is about 180 million years old. The Philippine Plate is younger and smaller than the Pacific. In subduction zones, the cold, dense crust sinks back into the mantle and collapses there.

As deep as the trench is, it is not the closest place to the center of the Earth. Since the planet bulges out at the equator, the radius at the poles is about 25 km less than the radius at the equator. Thus, parts of the seabed of the Arctic Ocean are closer to the center of the Earth than the depth of the Challenger.

The water pressure at the bottom of the trench is over 8 tons per square inch (703 kg per square meter). This is more than 1,000 times the pressure felt at sea level, or the equivalent of 50 jet planes stacked on top of a person.

Unusual volcanoes in the Mariana Trench

The chain of volcanoes rising above the ocean waves and forming the Mariana Islands reflects the crescent-shaped arc of the Mariana Trench. Interspersed with the islands are many strange underwater volcanoes.

For example, the underwater volcano Eifuku erupts liquid carbon dioxide from hydrothermal chimney-like vents. The fluid coming out of these pipes is 217 degrees Fahrenheit (103 degrees Celsius). At the underwater volcano Daikoku, scientists have discovered a pool of molten sulfur 410 meters below the surface of the ocean, which does not exist anywhere else on Earth.

Life and inhabitants in the Mariana Trench

Recent scientific expeditions found surprisingly diverse life in these harsh environments. Animals living in the deepest parts of the Mariana Trench survive in total darkness and extreme pressure, said Natasha Gallo of the Scripps Institution of Oceanography, who studied footage from Cameron's 2012 expedition.

Food in the Mariana Trench is extremely limited, since the deep gorge is far from land. Leaves, coconuts and trees rarely make it to the bottom of the trench, Gallo said, and dead plankton sinking from the surface must fall thousands of meters to reach Challenger Deep. Instead, some microbes rely on chemicals like methane or sulfur, while other creatures devour marine life further down the food chain.

The three most common organisms at the bottom of the Mariana Trench are xenophyophores, amphipods, and small sea ​​cucumbers(holothurians).

Single-celled xenophyophores resemble giant amoebas. Amphipods are shiny, shrimp-like scavengers commonly found in deep sea trenches. Holothurians may be a new species of bizarre, translucent sea cucumber.

"These are some of the deepest holothurians ever observed and were relatively numerous," Gallo said.

The scientists also identified more than 200 different microorganisms in the mud collected from the Challenger Deep. The mud was transported to the laboratory on land in special canisters, and is carefully stored under conditions that replicate the temperature and pressure at the bottom.

During the Cameron expedition in 2012, scientists also found bacterial mats in the Sirena Depth Basin, located in the area east of the Challenger Depth. These clusters of microbes feed on the hydrogen and methane released chemical reactions between sea ​​water and breeds.

In 2017, scientists reported that they had collected samples of an unusual creature dubbed Mariana snailfish, which lives at a depth of about 8,000 m. The snail's small, pink, and scaleless body is unlikely to survive in such an aggressive environment, but this fish is full of surprises, researchers report. The animal appears to dominate this ecosystem, diving deeper than any other fish and taking advantage of the lack of competition to devour the invertebrates abundantly inhabiting the trench.

Pollution in the deep

Unfortunately, the deep ocean acts as a potential sink for discarded pollutants and debris. In a recent study, a team of scientists from Newcastle University showed that man-made chemicals that were banned in the 1970s are still lurking in the deepest parts of the ocean.

During sampling of amphipods (shrimps, crustaceans), the researchers found extremely high levels persistent organic pollutants (POPs) in the adipose tissue of organisms. These include polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), chemicals commonly used as electrical insulators and flame retardants, according to a study published in the journal Nature Ecology & Evolution. These POPs were released into the environment as a result of industrial accidents and spills in landfills from the 1930s until the 1970s, when they were finally banned.

“We still think of the deep ocean as this remote and untouched realm, protected from human impact, but our research shows that unfortunately this is not true,” said Alan Jamieson of the University of Newcastle.

In fact, the amphipods in the study contained levels of contamination similar to those found in Suruga Bay, one of the most polluted industrial areas in the Pacific Northwest.

Since POPs cannot be destroyed naturally, they are stored in environment for decades, reaching the ocean floor as a result of pollution from plastic debris and dead animals. The pollutants are then carried from creature to creature through the ocean food chain, eventually leading to a concentration chemical substances much higher than surface level pollution.

"The fact that we have found these pollutants in one of the most remote and inaccessible habitats on earth truly proves the devastating impact that humanity is having on the planet," Jamison said in a press release.

The researchers say the next step is to understand the effects of this pollution and what it does to the ecosystem as a whole.

The height of Everest is 8848 meters. The mountain does not reach the “height” of the Mariana Trench for more than two kilometers. The bottom of the depression is hidden under the water column. Light does not penetrate there, ordinary marine inhabitants prefer not to dive so deep.

But even in such an inhospitable place there is life. Studies have shown that the absence of light and colossal pressure do not kill all organisms. True, those who live at the bottom have a specific appearance. Or maybe the bottom of the hollow is inhabited by real monsters that hide from human eyes?

Secrets of the Mariana Trench

The Mariana Trench was discovered by accident when the crew of the Challenger research ship was exploring the bottom in the Pacific Ocean. Suddenly, near the Mariana Islands, the apparatus sank heavily, pulling a steel cable. The ship literally hung in the water column. Then the rope was increased by a kilometer. And then more. And further. As a result, the Challenger went under water for eight thousand meters. It was dangerous to lower the apparatus further: the pressure would crush the structure, as if tin can. In the end, scientists realized that they had found the deepest point in the world, and they called it the "Challenger Abyss".

In 1931, people descended into the Mariana Trench for the first time. Navy Lieutenant Don Walsh and explorer Jacques Picard have a unique mission: to personally determine who lives at such a depth. The apparatus, the steel walls of which reached 13 centimeters in thickness, descended for five hours. At the bottom, Picard and Walsh "lay" for only 12 minutes. But even this time was enough to establish that undersea world cavities are not a sight for the faint of heart.

Picard and Walsh during the dive

The more perfect the devices became, the more frightening information came from the cavity. Some bathyscaphes recorded eerie sounds. Others are strange shadows of huge creatures. As a result science community split apart. Someone believed that prehistoric monster sharks were hiding in the waters of the gutter. Someone, on the contrary, was convinced that the most terrible creatures of the hollow are eyeless flat fish. Who actually lives at the bottom of the Mariana Trench?

Monsters of the Mariana Trench

In 1996, the Glomar Challenger sank into the waters of the Pacific Ocean. Per appearance the researchers nicknamed him "hedgehog". It was worth the "hedgehog" to go down halfway, as the operators "caught" eerie sounds, reminiscent of the grinding of metal. The apparatus was immediately brought to the surface. Boca steel structure crumpled, as if someone had chewed it. The steel cable 20 centimeters thick was almost bitten. The researchers came to the only, as it seemed to them, conclusion: the “hedgehog” collided with an unknown monster.

In addition, German scientists also claimed to have encountered the inexplicable. At the beginning of the 2000s, the Highfish apparatus descended into the Mariana abyss. At some point, the device froze and hung halfway. Cameras began to transmit images directly from the scene. According to the researchers, they saw with their own eyes the dark silhouette of a huge lizard. The creature swam first to the left, then to the right, aiming. Then the machine began to shake. "Highfish" responded to the attack with an electric discharge. The shaking ended and the creature disappeared.

Moreover, the fishermen who live in the waters of the Pacific Ocean absolutely agree with the scientists. Repeatedly, there were reports from the local population that a huge monster shark was swimming in the waters. The creature reaches a length of 30 meters and has sharp teeth. By the way, such teeth were repeatedly found on the coast. The average size of each reaches ten centimeters. Scientists have not yet been able to catch the monster. All that is there is a scratched "Hedgehog", teeth thrown out by the surf and eerie sounds. However, researchers are convinced that Carcharodon megalodon, a dinosaur that was the master of the ocean two million years ago, lives at the bottom of the depression.

And if the version with a prehistoric shark still withstands criticism, then other legends of the Mariana Trench seem incredible. So, the scientists who launched the Titan apparatus in 2012 are sure that they encountered aliens. The device descended in order to take photographs and film the underwater world. However, at some point, the cameras recorded strange objects. "Titan" seemed to be "surrounded" by several metal cylinders at once. They hung motionless in the water. The device swam closer, and the researchers saw that the cylinders are somewhat reminiscent of flying saucers. The Titan never surfaced, and with it the ocean swallowed up all the records. Despite this, scientists are convinced that the Mariana Trench is inhabited sentient beings. Of course, the bottom of the gutter is inhabited. But organisms familiar to the Earth live there. Although some are a real miracle of nature.

Real inhabitants of the Mariana Trench

The most interesting and creepy specimens of fish are found where light does not penetrate. Darkness gives birth to monsters who had to adapt to such a lifestyle. For example, anglerfish use a luminous lure attached to the antennae in front of the fish's mouth during hunting. And in the mouth of the angler is a palisade of sharp teeth. The stomachs of these monsters are perfectly stretched. As a result, they absorb prey that is several times larger than them, and then slowly digest it.


Live at the bottom of the Mariana Trench and bizarre sharks. For example, the goblin shark lives here, which got its name because of its strange appearance. It is interesting that for all the time it was possible to catch or find only 45 specimens. The goblin shark has a unique jaw structure. During the hunt, she is able to throw them forward, catching the victim. The monster then retracts its jaws back, along with the prey. The protrusion on the nose, which is why the creature was nicknamed the "goblin", consists of many electrically sensitive cells. Thanks to the growth, the shark perfectly feels the prey and quickly determines its location.

It should be noted that deep sea fish extremely voracious. This is not due to greed, but to limited resources. The Black Liverthroat, or as the scientific community calls it, Chiasmodon, is a gluttonous champion. Externally, the fish looks inconspicuous. Its length reaches only 20 centimeters. The live-eater does not have large fins, developed muscles, and even scales. But fish bones are extremely elastic. The mouth and stomach of the larva are also strongly stretched. Thanks to this, a small creature absorbs prey several times larger than itself. And the victim is often still trying to get out.

Almost all inhabitants of the Mariana Trench are predators. Due to the lack of light, the flora in the gutter is very sparse. All that remains for the underwater monsters is to devour each other. This explains why the Mariana fauna is so toothy. In addition, each fish has a unique mechanism for obtaining food. For example, a viper fish can open its mouth more than 100 degrees. To do this, the lower jaw with long teeth moves forward. The viper clings to the victim and literally stuffs it into the mouth.

In addition, less toothy, but no less amazing creatures live at the bottom of the depression. The appearance of a fish called macropinna, to put it mildly, is specific. The creature's forehead is transparent. Hidden under a layer of transparent fabrics are the eyes, which rotate freely in their lodges. The space around the eyes is filled with a clear fluid. Thanks to this unusual structure, the macropinna sees perfectly in almost complete darkness. Moreover, the fish notices the prey even when it changes direction abruptly: the field of view near the eyes is impressive.


When a cat falls from a great height, it lands on its belly instead of its paws, which helps it survive.

When falling from a great height (above the seventh floor), the cat's body accelerates until it reaches the maximum speed, after which it goes into free fall. In this state, the cat no longer feels gravity and cannot determine which is up and which is down. Then she spreads her paws in different directions, increasing the surface of her body, like a parachute, and the fall speed decreases, and the chances of survival increase.

A sloth can starve to death with a full stomach of food.

Animal horns are a huge cancer

Probably, in the memory of each of us there are concepts from school curriculum in geography, monotonously repeating in the voice of a teacher: the highest point on earth is Everest, the deepest is the Mariana Trench. While still schoolchildren, we listened and imagined, what a depth, as much as 11022m! But, probably, they could not even imagine how many secrets and unknown inhabitants this abyss hides in itself!

The Mariana Trench (aka the Mariana Trench and the Womb of Gaia) was formed several million years ago due to shifts in tectonic plates. According to the latest data from American scientists, its depth is 10971m, while Soviet researchers in 1957 recorded the familiar figure of 11022m. The water pressure at the bottom of the gutter is 1100 times higher than normal atmospheric pressure.

So who, after all, decided to go down far into the ocean and how many still unsolved mysteries she asked us?

The first to measure the depth of the depression were members of the crew of the Soviet research vessel Vityaz in the aforementioned 1957. And it was they who refuted the azoic theory, according to which it was believed that at a depth below 7000 meters there are no life forms. Scientists have identified colonies of barophilic bacteria that can only survive at very high pressures.

In 1960, the American bathyscaphe Trieste, designed by Jacques Picard, set a new record by reaching the bottom of the depression and staying there for 12 minutes. And to this day, no one has been able to repeat this! Sinking into the ocean abyss, the crew members saw two 30-centimeter fish, which proved by itself that even under such high pressure and in pitch darkness life exists.

The same, after more than three decades, was proved by the research of the Kaiko automatic bathyscaphe from Japan. He managed to collect soil samples from the bottom of the deepest trench, where 13 species of unicellular organisms were found that were not previously classified by science. What is surprising, they have existed for more than one billion years!

And in 2009, the American deep-sea robot "Nereus" descended to the depth, which transmitted videos and photos taken in the thickness of the ocean to land via a special cable. With his lens, he also managed to catch photofluoric fish, in which some parts or the entire surface of the body emit light.

In addition to them, as well as a number of protozoa and various types of barophilic bacteria, invertebrates in long chitinous tubes, rhizopods with a cytoplasmic body and a turtle (foraminifera), isopods, gastropods... The fish that exist there, in search of food, also stray into schools. But there is something that distinguishes these creatures from the usual marine life for us - their terrifying appearance! Huge teeth and eyes rotating in different directions, sharp spikes instead of fins, or, in general, the absence of a mouth and anus, as in the 2-meter living here giant worms… One of the most interesting discoveries was the dragon fish. This fish emits infrared rays with its black body, and then catches their reflection. These ocean inhabitants are of great importance in the development of biology and oceanology.

But hiding under water and someone still misunderstood and unknown. It is not in vain that sometimes on the ocean coasts, fishermen find the bodies of unusual monsters thrown out by the elements, up to 70 meters long.

And within the Mariana Trench, the teeth of the giant shark megalodon were found. These prehistoric monsters weighed about 100 tons, had a length of 24 meters, and a mouth width of 2 meters. It was believed that they disappeared from the face of the Earth 2-2.5 million years ago, but the 10-centimeter teeth from the gutter are about 11-24 thousand years old! Does this mean that not all sharks died out, some of them continued to exist in the Womb of Gaia?

But there are even worse facts! The vessel "Glomar Challenger" in 2003 studied the bottom of the depression. Suddenly, his devices recorded strange sounds, as if someone was sawing metal cables, and shadows of creatures 12-16 meters in height appeared on the monitor, somewhat reminiscent of two-headed dragons. Scientists were afraid that the 9-meter robot could remain at the bottom and raised it to land. What they saw was horrifying. The side of the "hedgehog" (the so-called spherical apparatus) was deformed, and the powerful cables holding it seemed to be sawn.

The German apparatus "Highfish" suddenly braked sharply at a depth of 7000m. To find out the reason, the crew members turned on the infrared light and saw how their ship fell into the mouth of a huge creature that looked like ancient lizard. And this lizard is diligently trying to figure out the ship. With difficulty coming to his senses, the researchers decided to use " electron gun". Having received a dose of electric current, the monster released the bathyscaphe and disappeared.

Unfortunately, there are no pictures of these inhabitants of the ocean, which makes it possible for skeptics to laugh and elevate these stories to the rank of fairy tales. However, ufologists and oceanologists, nevertheless, do not lose hope in the future to conduct more research and to prove that the Mariana Trench is not only one of the geomorphological poles of our planet, but a place where a lot of unknown things are hidden, unknown to science. After all, everything unknown has long attracted a person, and new immersions and research only add questions on this topic, thereby keeping the inhabitants of the Earth in constant tension and inexhaustible interest.
