"Now about 200 meters under the sea, you can see that the surrounding light is already very dark."
"200 meters is a critical point in the deep sea. Going down here, the light intensity and temperature will change dramatically."
As the submarine went downwards, Ning Fei told netizens about the world under the sea.
"Above 200 meters is a shallow water area, where there is sufficient light and abundant algae, so there are the most fish."
"Every time I get out of the sea, the scene is the most magical!"
Ning Fei continued to drive the submarine downward. He was like a tourist on an alien planet, leading everyone to experience another world.
"Now it's 500 meters under the sea, and the number of species has decreased a lot."
"However, fish in shallow water will still swim down frequently. In summer, when the sun shines directly on the sea, the temperature in shallow water is very high, and many fish will dive into the deep sea to escape the heat."
"500 meters deep on the seabed is the habitat of blue whales."
"Further down is deeper water."
"For example, sperm whales usually live below a thousand meters. Last time we were able to see a pod of sperm whales in shallow waters, which is considered very rare."
"This is also enough to illustrate the power of marine life. In a thousand-meter sea, humans will be squeezed to death by pressure in an instant, but powerful marine life such as sperm whales can live very well."
Ning Fei's narration was very leisurely and relaxing.
Listening to his voice and looking at this magical scene, netizens felt it was particularly magical.
[Increased knowledge again!]
[I have never listened so seriously to a class!]
[It feels really good to learn ocean knowledge like this.]
[Ning Guanzhu’s science popularization time!]
Further down, it gets deeper and darker.
Ning Fei was driving the submarine and had chosen to turn on the lights on the submarine.
There are lights on the front and sides of the submarine.
So netizens can also see the surrounding scenery clearly.
Going down to the deep sea, the number of fish is indeed much smaller.
Ning Fei checked the submarine's dashboard and found that oxygen could still be supplied for about six hours, and the pressure was far from reaching the critical value, so there was no safety issue at all.
At this time, netizens saw that something seemed to be shining in the surrounding sea.
The light was very small and weak.
[what is that?]
[Is there light in such a deep sea?]
[Sure enough, light is everywhere!]
Netizens were very confused.
After a while, everyone discovered that seven or eight small points of light had gathered around the submarine.
"In the sea area of about 1,000 meters, many creatures have evolved lighting organs. They can emit light themselves, just like fireflies in the forest."
"There are many luminous creatures, some of which humans have not yet named."
"And they are phototactic and will wander around when they see light."
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 their heads, some are small fish that are transparent and glowing blue, and some look like a glowing flower, and you can’t tell what their structure is.
It's almost to the bottom of the sea.
"According to the submarine's echo detection, I will soon reach the bottom of a thousand meters."
"This is the real deep sea."
"Both sperm whales and giant squid live in this area."
"If you're lucky, you might even see a battle between two prehistoric beasts."
Ning Fei said again.
Netizens were speechless after hearing Ning Fei's words.
Do you call this good luck when you encounter a sperm whale and a king squid that are more than ten meters long at a thousand meters under the sea
This is almost killing me!
At this time, the submarine turned on its lights and continued downward.
Not long after, Ning Fei finally saw the black mud.
Where the light swept over, netizens saw a fish emerge from the mud in a hurry, and then swam away as if it were flying.
At first no one noticed the fish because the fish was well camouflaged with only one mouth exposed.
As soon as the light shone, the fish was probably scared and ran away.
"The way many fish in the deep sea hunt is to sit back and wait."
"They will find ways to blend in with the surrounding environment. Not to mention that there is almost no light at the bottom of the sea. Even if it is completely bright, the prey may not be able to find where the predator is."
After arriving at the bottom of the sea, Ning Fei also wandered forward.
He wants to find the sunken ship at the bottom of the sea.
Of course, since it is a live broadcast, the purpose cannot be too clear.
Otherwise it will make people suspicious.
Therefore, Ning Fei started to drive aimlessly and explain casually.
Slowly approaching the sunken ship on the seabed without leaving a trace.
"Look at the fish next to you. There is a small lantern on top of its head. It is a huge and ugly fish."
"This fish is called an anglerfish."
Ning Fei looked out from the glass on the side of the submarine and saw a very ugly and strange fish appearing.
Netizens also took a look.
"This fish has a very interesting characteristic. Does anyone know what it is?"
Ning Fei asked again.
[Appeared, Guanzhu Ning’s question-and-answer session in class!]
[Hahaha, it’s exactly the same as what the teacher said, I feel that way!]
[Teacher, if I knew, why would I still be listening to the class!]
[Guanzhu Ning, stop being so secretive and tell me now!]
Everyone is very enthusiastic about learning knowledge. If their former teachers knew about this scene, they would probably be shocked.
"The male anglerfish is very small. According to normal proportions, the female anglerfish is 60 times larger than the male anglerfish."
Ning Fei gave the answer.
What he said immediately aroused the interest of netizens.
[What, 60 times?]
[What is the concept of sixty times? To give a simple example, the volume of a human being is 0.05 cubic meters based on 50 kilograms. When a cat is a teenager, its volume is about 1000 cubic centimeters, which is 0.001 cubic meters]
[In other words, the volume of a human is about 50 times that of a cat.]
[Thanks to my brother for the popular science. The size difference between the female and male fish is so big, so you know how they do it.]
[Yes, why do they give birth to babies like this?]
Everyone is obviously particularly interested in a certain aspect of the issue.
Ning Fei also expected this, so he told netizens:
"This fish is amazing."
"The male anglerfish will swim to the abdomen of the female anglerfish and stick to it."
"Then, the blood vessels and muscles in their bodies will slowly fuse together."
"The male anglerfish becomes part of the female anglerfish and never becomes separated again."
"The way they mate, they do it at a cost."
"This phenomenon is called 'sexual parasitism' in the scientific community."
After hearing Ning Fei's words, netizens couldn't help but widen their eyes.
[real or fake? So magical?]
[Hey guys, I checked the information, and it seems to be true. The male anglerfish will turn into a tool fish that provides sperm.]
[Guanzhu Ning is right, but not all anglerfish will choose to be parasitic. Some will never be parasitic on females throughout their lives, and some will leave gracefully after completing 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 really magical.]
Netizens were full of praise.
Obviously, the vivid and interesting knowledge made everyone experience the joy of learning.
At this time, Ning Fei continued to move forward.
He looked at the coordinate display in the submarine and knew that he was getting closer to the deep-sea sunken ship.
At this moment, a huge black shadow slowly appeared in the live broadcast footage.
