Man's yearning for the sea is no less than his yearning for the universe. With the continuous development of science and technology, human beings are exploring the universe more and more, as well as the deep sea. But you know what? About 70% of the earth's surface, and the deepest part of the ocean is more than 1 1000 meters. Humans only know 5%, so what is there in such a mysterious ocean world? After watching the watermelon video, you will know by creating a short video of the human brain hole solar system.

The ocean has always been very mysterious to human beings. You should know that 94% of the creatures on the earth are aquatic creatures, and human beings are only very special terrestrial creatures to them. So what's in the ocean? Let's start with a depth of three meters in the ocean. First of all, the depth of three meters is about the depth of our human swimming. At a depth of 20-30 meters, we can see some common coral reefs and aquatic plants. Below sea level 100 meter is the limit diving depth of many professional divers. There are giant octopuses living here in the North Pacific Ocean, which is at this depth. Many divers can't do it by people.

It is difficult to have photosynthesis below 200 meters above sea level, so there are few green plants here. It really entered the animal world at an altitude of 500 meters, and the deepest diving of the world's largest mammal, the blue whale, was here. At an altitude of 900 meters, a large number of king squid live. Below the altitude of 1000 meters, it is almost dark here, and even life is very scarce. The deep sea area is 3000 meters below sea level, where the temperature is very low and the pressure is very high. Few fish live here, but sperm whales, as the largest creatures with the deepest diving depth, live here. 3,800 meters below sea level, which is the depth at which the Titanic sank.

6000 meters below sea level, you reach the deep sea area. At an altitude of more than 8,000 meters, the China diving team discovered the Mariana snail fish, a very old creature. At an altitude of 10000 meters, humans discovered a huge primitive single cell, which is also the last creature found in the deep sea. At the altitude of 1 1000 meters, which is the deepest part of Mariana Trench, it is called Challenger Abyss, and no living things have been found here for the time being.

In fact, there are many excellent video creators and wonderful short videos on watermelon video. Besides letting you know about the ocean and the universe, there is a lot of life-related knowledge. Pay attention to watermelon videos and satisfy your curiosity!
