Life from the deep, an impossible puzzle. The hidden world off the oceans

On January 23, 1960, Don Walsh and Jacques Piccard descended into the Mariengrube with the help of a submersible at a depth of 10915 meters. It was an extremely dangerous mission, but it was successfully completed.

Marian's pit was located in the Pacific Ocean and occupies an area of ​​2500 kilometers. In order to avoid tragedies, the use of robots to study the weird place was chosen. Fish that feed on organic matter have been discovered, but the question remains as to how they could adapt to such conditions.

This year, the American Victor Vescov repeated the record of 1960 and reached a depth of 10915 meters. Vescov explored the abyss aboard a submarine that could withstand the enormous sea pressure for four hours.

He discovered four new types of crustaceans, much like shrimp. As a breeder, Vescov has also discovered a plastic bag and candy wrappers.

The pressure in the bottom of the abyss is 108.6 MPa, which is 1100 times the normal atmospheric pressure. In order to live in this abyss, small crustaceans have formed around the true armor of the exoskeleton, which helps them to withstand this great pressure ,

At extreme pressure in the precipices, calcium carbonate, which forms the exoskeleton, reacts much more easily with carbon dioxide and dissolves in water, leaving the body of these invertebrates unprotected. Aluminum armor protects your body so you can live at very deep depths.

Crustaceans caught at depths over 10,000 meters measure about 3 cm. To achieve this armor, crustaceans use sugar-based compounds to extract aluminum ions from the shore and sand from the seabed, remains of marine plants.

So far, these amphipods are the only known that can win the aluminum and the coast and have gotten used to the hellish life from the abyss.
