Exploring the ocean is much more difficult than exploring space. The ocean covers an area of ??about 360 million square kilometers, accounting for 71% of the earth’s surface area. It can be said that humans have only explored less than 5% of the seabed, and the remaining 95% of the world is unknown.

Let me take you to dive together to see what is 10,000 meters under the sea?

Depth 3 meters: This is the depth at which ordinary people swim.

30 meters under the sea: This is where coral reefs and undersea plants grow.

100 meters under the sea: The toad fish, known as "foie gras of the sea", is here waiting for prey to come to you. The male fish is only one-tenth of the female fish. It spends its whole life just to get close to it. A rich woman.

The above is the photosynthesis zone. In this zone, most of the visible light in the sun can shine in, and phytoplankton on the surface of the ocean live here.

The middle zone between 200 meters and 1,000 meters under the sea is where the sun is basically not exposed, the oxygen content is very low, and the seawater temperature has dropped from 20 degrees Celsius to 4 degrees Celsius.

300 meters under the sea: Here you can encounter the largest crustacean in existence, the Giant Crab, with 4-meter-long legs.

The water pressure here is equivalent to a 540-pound fat man dancing on every inch of your skin.

500 meters under the sea: the deepest point where the blue whale lives. Its tongue is as heavy as an elephant, and its blood vessels are so wide that people can swim in it.

600 meters under the sea: The big-finned anus is staring with a pair of tube-shaped eyes pointing upward, searching for delicious small fish swimming from above. By the way, its head is transparent.

In the deep zone of 1,000 to 4,000 meters under the sea, almost all sources of energy are cut off. The temperature is constant at about 4 degrees Celsius. Although the water pressure is already huge, a large number of organisms still survive. The only visible light here is produced by luminescent organisms.

Warning ahead, the following deep-sea fish look very random: Black's flat-nosed chimaera, giant silver ax fish, etc.

Under the sea

1,300 meters: There lives the European giant shark. Its mouth and jaws are separate. When you open your mouth to eat, the teeth will fly out to bite things. Live and then take it back.

Under the sea

2200 meters: You can see sperm whales and giant squids fighting fiercely.

Under the sea

2800 meters: The Dumbo octopus is a rare deep-sea fish with a cute appearance. Its fins look like elephant ears.

Bottom 3,000 meters: The pressure is 3,000 times that of the ground, and it takes several months for sea snow to fall. Marine snow is a slime synthesized by protists and bacteria living in surface seawater.

3100 meters under the sea: giant squid can appear and disappear.

3750 meters under the sea: This is the depth where the Titanic sank.

3800 meters under the sea: This is the average depth of the world’s oceans.

4000 to 6000 meters under the sea is the "abyssal zone". It is not only dark, but also very cold. The water temperature is close to freezing point. Coupled with the terrible pressure, few living things exist.

All living creatures are invertebrates, and many fish have degenerated into blindness, relying only on tactile organs instead of visual organs, such as sea cucumbers, tripod fish, jellyfish, etc.

5,000 meters under the sea: There is a lack of food here, so the fang-tooth fish staying here are not picky about food and eat whatever they see. The food mainly falls from the oceans in the previous layers.

5900 meters under the sea: Patrick lives here.

The 6,000 to more than 10,000 meters under the sea is the "deep sea zone". Generally, such deep places can only be found in ocean trenches and submarine canyons. Although the water pressure and water temperature here are unimaginable, there are still a small number of unimaginable places. Vertebrates thrive here.

7062 meters under the sea: the deepest dive record of China’s Jiaolong in the Mariana Trench.

8,000 meters under the sea: The salmon that everyone usually eats is here.

The seabed is 11,034 meters, which is named Mariana Deep. This is the largest seabed depth known to mankind, enough to fit the world's highest peak, Mount Everest, into it.

At present, people’s understanding of the depths of the seabed is far less than their understanding of space. If the level of science and technology improves, and people can take a submersible to swim on the seabed 10,000 meters below, they will definitely be able to discover it by then. More surprising creatures, this is no less than an exploration of the universe!
