“Now that we’re about 200 meters below the sea, you can see that the surrounding light is already very dim.”
“200 meters is a critical point in the deep sea. From here down, the light intensity and temperature will undergo a huge change.”
As the submarine descended, Ning Fei told the netizens about the world under the sea.
“Above 200 meters is the shallow water area. There’s plenty of light and algae, so there are the most fish.”
“Every time we go into the sea, the scene is the most fantastic!”
Ning Fei continued to drive the submarine downwards. He was like a tourist who had come to an alien planet, leading everyone to experience another world.
“Now it’s 500 meters under the sea. The number of species has decreased a lot.”
“However, the fish in the shallow waters often swim down. In summer, the sun shines directly into the sea. The temperature in the shallow waters is very high. Many fish will dive into the deep sea to escape the heat.”
“The place 500 meters under the sea is the habitat of the blue whales.”
“Further down is the deeper waters.”
“For example, sperm whales usually live below 1,000 meters. The last time we saw a group of sperm whales in the shallow waters, it was considered very rare.”
“This is enough to show how powerful marine creatures are. In an area of 1,000 meters, humans would be instantly crushed to death by the pressure. However, powerful marine creatures like sperm whales can live very well.”
Ning Fei’s narration was very leisurely and relaxed.
Listening to his voice and looking at this magical scene, the netizens felt that it was especially magical.
[ my knowledge has increased again! ]
[ I’ve never been so serious in class before! ]
[ it feels good to learn marine knowledge like this. ]
[ Abbey Dean Ning’s time for science popularization! ]
Further down, it became deeper and darker.
Ning Fei was driving the submarine and had already chosen to turn on the lights on the submarine.
There were lights on the front and both sides of the submarine.
Therefore, the netizens could also see the surrounding scenery clearly.
When they went down to the deep sea, the number of fish was indeed much less.
Ning Fei checked the dashboard of the submarine. Oxygen could still be supplied for about six hours, and the pressure was far from the critical value, so there was no problem with safety.
At this time, the netizens saw that there seemed to be something glowing in the surrounding sea area.
The light was very small and very weak.
“What is that?”
“There’s actually light in such a deep sea?”
“Indeed, light is everywhere!”
The netizens were very confused.
After a while, everyone discovered that there were already seven or eight small light spots gathered around the submarine.
“In the sea area of about 1,000 meters, many creatures have evolved lighting organs. They can emit light on their own, just like fireflies in the forest.”
“There are many creatures that emit light, and some creatures are not named by humans.”
“Moreover, they have phototaxis. When they see light, they will wander nearby.”
Ning Fei explained.
There were many small fish around the submarine.
These small fish were very strange.
Some were lantern fish with a lantern on their head, some were transparent fish that emitted blue light, and some looked like a glowing flower. No one could tell what they were made of.
They were almost at the bottom of the sea.
“According to the submarine’s echo detection, I’m about to reach the bottom of the sea one thousand meters away.”
“This is the real deep sea.”
“Both the sperm whale and the giant squid live in this area.”
“If we’re lucky, we might even be able to see the battle between two prehistoric behemoths.”
Ning Fei said again.
The netizens were speechless when they heard Ning Fei’s words.
To encounter a sperm whale that was more than 10 meters long and a giant squid that was more than 10 meters long at a place 1,000 meters below the ocean floor, do you call that Lucky?
It was going to kill him!
At this moment, the submarine turned on the lights and continued to descend.
Not long after, Ning Fei finally saw the black mud.
At the place where the lights swept past, the netizens saw a fish that scrambled out of the mud and swam away as if it was flying.
At first, no one noticed the fish because it had disguised itself very well and only revealed its mouth.
When the light shone, the fish was probably afraid and ran away.
“Many fish in the deep sea hunt by waiting for prey.”
“They will think of ways to blend into 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 the hunter.”
After arriving at the bottom of the sea, Ning Fei also strolled forward.
He wanted to find the sunken ship at the bottom of the sea.
Of course, because it was a live broadcast, the purpose could not be too clear.
Otherwise, it would make people suspicious.
Therefore, Ning Fei started driving aimlessly and casually, explaining.
Without leaving a trace, he slowly approached the sunken ship at the bottom of the sea.
“Everyone, look at the fish next to us. There is a small lantern on its head. It is an extremely ugly fish.”
“This fish is called the monkfish.”
Ning Fei looked out from the glass on the side of the submarine and saw a very ugly strange fish.
The netizens also looked over.
“This fish has a very interesting feature. Do you know what it is?”
Ning Fei asked again.
“It’s here. It’s Abbey Dean Ning’s question-and-answer session!”
“Hahaha, it’s exactly the same as what the teacher said. I have that feeling now!”
“Teacher, if I knew that, why would I listen to the lecture?”
“Abbey Dean Ning, don’t keep me in suspense. Tell me quickly!”
Everyone was very enthusiastic about learning knowledge. If their former teacher knew about this scene, he would probably be shocked.
“The males of the monkfish are very small. According to the normal ratio, the female monkfish is 60 times more than the male monkfish.”
Ning Fei gave the answer.
His words immediately attracted the interest of the netizens.
[ what, 60 times? ]
[ what does 60 times mean? To give a simple example, the size of a human is 0.05 cubic meters based on 50 kilograms. When a cat is young, its size is about 1,000 cubic centimeters, which is 0.001 cubic meters. ]
[ in other words, the size of a human is about 50 times that of a cat. ]
[ thank you for your explanation. The size difference between females and males is so big, so how do they… you know. ]
[ yeah, how do they give birth? ]
Everyone was obviously very interested in a certain aspect.
Ning Fei also expected this, so he said to the netizens:
“This fish is very magical
“The male anglerfish will swim to the female anglerfish’s abdomen and latch onto it
“Then, the blood vessels and muscles in their bodies will slowly fuse together
“The male anglerfish will become a part of the female anglerfish and will never separate again
“Their mating method can only be carried out at the cost of sacrifice
“In the scientific world, this phenomenon is known as sexual parasitism.”
The netizens could not help but widen their eyes when they heard Ning Fei’s words.
[ are you serious? Is it that magical? ]
[ good lord, I’ve checked the information and it seems to be true. Male anglerfish will become a tool fish that provides sperm. ]
[ Abbey Dean Ning is right. However, not all anglerfish will choose to parasitize. Some will never parasitize a female in their entire lives. Some will leave after completing their mission and continue living their lives. ]
“I see.”
“I didn’t expect such a species to exist in the deep sea. Nature is really amazing.”
The netizens were full of admiration.
Obviously, the vivid and interesting knowledge made everyone experience the joy of learning.
At this moment, Ning Fei continued to move forward.
He looked at the coordinates in the submarine and knew that he was getting closer and closer to the sunken ship.
Just then, a huge black shadow appeared on the live camera.
