Chapter 381

"Now about 200 meters under the sea, you can see that the light around is very dark."

"200 meters is a critical point of the deep sea, where down, the light intensity and temperature will change dramatically."

Submarine side down, Ning Fei side to tell netizens about the world of the seabed.

"200 meters above belongs to the shallow water area, where there is sufficient light and rich algae, so fish is the most."

"Every time I just go to the sea, the scene is also the most fantastic!"

Ning Fei continued to drive the submarine down, he was like a tourist to the outside world, leading you to appreciate another world.

"It's 500 meters under the sea, and the number of species has decreased a lot."

"However, the fish in shallow water often swim down. In summer, the sun shines directly on the sea. The temperature in shallow water is very high, so many fish will dive into the deep sea for summer vacation."

"500 meters under the sea is the habitat of blue whales."

"Further down is the deeper sea."

"Sperm whales, for example, usually live under one kilometer. Last time we saw a group of sperm whales in shallow water, it was very rare."

"This is also enough to show the strength of marine life. In the one kilometer sea area, human beings will be crushed by pressure and die instantly, but powerful marine life such as sperm whales can live well."

Ning Fei's story is very leisurely and relaxing.

Listening to his voice, looking at this magical scene, Netizens feel particularly magical.

[knowledge is rising again! 】

[I have never been so serious in class! 】

[it's really good to learn marine knowledge in this way. 】

[Ning Guanzhu's popular science time! 】

further down, it gets deeper and darker.

Ning Fei is driving the submarine and has chosen to turn on the lights on the submarine.

There are lights in the front and on both sides of the submarine.

So netizens can also see the surrounding scenery.

Down to the deep sea, the number of fish is really much less.

Ningfei checked the instrument panel of the submarine. The oxygen can still be supplied for about six hours, and the pressure is far from reaching the critical value, so there is no safety problem at all.

At this time, netizens see that there seems to be something glowing in the surrounding waters.

The light was very small, very weak.

What's that? 】

[is there light in such a deep sea? 】

[sure enough, light is everywhere! 】

netizens are very confused.

After a while, we found that seven or eight small light spots had gathered around the submarine.

"In the sea area of about 1000 meters, many organisms have evolved lighting organs, which can emit light themselves, just like fireflies in the forest."

"There are a lot of luminous creatures, and some of them are unnamed."

"And they have phototaxis. When they see light, they wander around."

Ning Fei explained.

There are many small fish around the submarine.

These little fish are very strange.

Some are lantern fish with a lantern on top of their heads, some are small transparent fish with blue light, and others look like a luminous flower, and they can't see the structure.

It's almost to the bottom of the sea.

"According to the submarine's echo detection, I'm going to reach the bottom of the sea one kilometer away."

"This is the real deep sea."

"Sperm whales and giant squid live in this area."

"If you're lucky, maybe you can still see two prehistoric giants fighting."

Ning Fei said again.

After hearing Ning Fei's words, netizens were speechless for a while.

One kilometer from the bottom of the sea, you meet a sperm whale more than ten meters long and a giant squid more than ten meters long. Do you call this luck?

It's going to kill you!

At this point, the submarine lights on and continues down.

Before long, Ning Fei finally saw the black mud.

Light swept the place, netizens see a fish rush out of the sand, and then fly away.

At the beginning, we didn't find the fish, because the fish camouflaged very well and only showed a mouth outside.

As soon as the light shone, the fish was afraid, so he ran away.

"A lot of fish in the deep sea wait for their prey."

"They will try to integrate with their surroundings, not to mention that there is little light at the bottom of the sea. Even if it is completely bright, the prey may not be able to find out where the hunter is."

After arriving at the bottom of the sea, Ning Fei also wandered forward.

He wants to find the wreck.

Of course, because it is live, the purpose can not be too clear.

Otherwise, it would be suspicious.

Therefore, Ning Fei began to open aimlessly and explain at will.Without any trace, the sunken ship slowly leaned towards the bottom of the sea.

"Look at the fish next to you. There is a small lantern on the top of your head. It's a very ugly fish."

"This fish is called minnow."

Ning Fei looked out from the side glass of the submarine, and a very ugly strange fish appeared.

Netizens also looked in the past.

"This fish has an interesting feature. Do you know what it is?"

Ning Fei asked again.

[there is a question session of Ning Guanzhu in class!

as like as two peas, the feeling is there. 】

[teacher, if I knew, what else would I do! 】

[ningguanzhu, don't play tricks, talk about it quickly! 】

everyone has a high enthusiasm for learning knowledge. If their former teachers knew about this scene, they would be surprised.

"Males are very small, and in normal proportion, females are 60 times as large as males."

Ning Fei said the answer.

He said this, immediately aroused the interest of netizens.

[what, 60 times? 】

[what's the concept of 60 times? For a simple example, the volume of a person is calculated as 50 kg, which is 0.05 cubic meters, while that of a cat is about 1000 cubic centimeters, which is 0.001 cubic meters when it is young]

[that is to say, the volume of a person is about 50 times that of a cat. 】

[thank you, brother Kop, the size difference between female and male is so big, so how do they...? you know what. 】

[yes, how do they have children? 】

you are obviously very interested in a certain aspect.

Ning Fei also expected this, so he said to netizens:

"this kind of fish is very magical."

"The male swims to the belly of the female and attaches to it."

"Then, the blood vessels and muscles in their bodies will slowly blend together."

"The male becomes part of the female and never separates again."

"The way they mate is at the cost of sacrifice."

"In the scientific community, this phenomenon is called" sexual parasitism. "

Hear Ning Fei's words, netizens can't help but stare big eyes.

Is it true or false? So amazing? 】

[good guy, I checked the data and it seems that it is true. The male fish will become a tool fish providing sperm. 】

[what Ning Guanzhu said is right, but not all of them will choose to parasitize. Some of them will not parasitize females all their lives, and some will leave after finishing their tasks and continue to live their own lives. 】

[I see. 】

[I didn't expect that there are such species in the deep sea. Nature is amazing. 】

netizens were all amazed.

Obviously, the vivid and interesting knowledge makes us feel the joy of learning.

At this time, Ning Fei continued to move forward.

He looked at the coordinates in the submarine and knew that he was getting closer to the sunken ship.

At this time, a huge shadow appeared slowly in the live camera.
