Mariana Trench is located in the western Pacific Ocean. Known as the deepest ocean in the world, it has a total length of 2,550 kilometers and a depth of over 1 1 km. Even Mount Everest, the highest peak in the world, will be submerged here. In the deepest part of the trench, the water pressure is high, the temperature is low, the oxygen content is low, and the food resources are extremely scarce, so it has become one of the worst environments on earth.

I have always taken it for granted that there is nothing deep in this trench, and it is impossible for creatures to survive here.

However, in 1957, scientists from the former Soviet Union made a detailed survey of the Mariana Trench on the research ship Vitaz, and found life at a depth of 7000m. Until today, more and more evidence shows that there are a lot of life in the Mariana Trench, and many creatures are still very strange.

1960 65438+1On October 23rd, Swiss explorer Jacques piccard and the US Navy took the submarine Trieste to the trench 1 1000 meters deep. This depth, also known as Challenger Abyss, is the deepest record of human exploration of the seabed.

They stayed in Challenger's abyss for almost 20 minutes, and after landing, they announced to the world their discovery in the depths of the trench: there is life at the bottom of the trench. The news shocked the whole world. Because in such a deep place, the water pressure is more than 1000 times of the sea level. With such a strong water pressure, steel will deform directly, not to mention flesh and blood!

However, many years later, someone discovered Jacques' diary and published its contents. According to the diary, when he was diving with the US Navy, he once saw a huge unidentified disc-shaped creature, which suddenly disappeared after diving for a few minutes.

What species this creature is is unknown. Some people speculate that it may be the offspring of some ancient creature, because living in the depths of the trench, human beings can not explore, so it is normal not to know.

1985, a scientific research team from the United States put a probe named "Hedgehog" into the Mariana Trench for scanning. The detector was in a normal state at first, but when it dived deeper, it suddenly sent back a strange sound to the researchers on the ground.

The researcher was frightened and called the detector back, but it seemed that the detector was caught by something and could not move. After struggling for three hours, the instrument finally escaped back. Surprisingly, the exterior of the detector was damaged, as if it had been bitten by something and the cable was broken.

Detectors that can stay deep in the ditch have certain resistance to water pressure. However, such serious damage will still happen. What a powerful creature it takes to create this scene!

Later, after analyzing the researchers' reports, some experts put forward their guesses. They speculated that this powerful mysterious creature was probably Megalodon.

Megalodon lived from the late Miocene 6.5438+0.5 million years ago to the early Pleistocene 2.6 million years ago. It is the top marine predator in its life, and now it is considered as an extinct creature. Their average body length is 14m, weighing 40 tons, and their maximum bite force can reach 20 tons. Paleontologists once called them "the strongest and largest creatures in the history of the earth."

Surprisingly, scientists also found a huge tooth at the bottom of the trench. After research, it is concluded that this is the tooth of Megalodon. Has Megalodon been hiding in Mariana Trench?

Bian Xiao believes that Mariana Trench is full of unknowns and mysteries. However, the Mariana Trench is only a small microcosm of the earth, and there are too many wonders waiting for us to explore.
