The pressure in the deep sea at 1, meters is amazing. At 1, meters, the pressure in the deep sea reaches an amazing one ton per square centimeter. There is no diving equipment in the world for human beings to dive into. At present, the deepest diving tool for human beings is only 4 meters. Only about 4 meters under the sea, human beings have to bear 27 tons of pressure. Because of this, the fish in the deep sea are flat. Today, humans have not found any living fish at 84 meters. In such a deep seabed, the sun can't shine, and it is conceivable that the deep sea is silent. The following data are the survival depth of various organisms
