These creatures in the ocean always give people a sense of wonder.

Netizens resonated with the survival method of sea spiders.

They all feel that their lifestyle is similar to their own.

Su Ran said: "Although sea spiders may seem insignificant in the ocean, they are able to adapt to various environments and demonstrate strong vitality."

“Even seemingly insignificant existence has its own unique way of survival.”

"And the sea spiders' lifestyle also makes people think that sometimes it's good to slow down and enjoy the peace and quiet of life."

The audience was surprised to find that Su Ran not only had outstanding acting talent, but was also a hidden philosopher.

"What Su Ge said does make sense."

"To be honest, my mom often doesn't let me lie flat. Actually, there's nothing wrong with lying flat."

"To be honest, I really like him. He and I are cut from the same cloth."

"Let's just say that the sea spiders are just too strong. This kind of trash is exactly like me."

Although the audience were all making fun of themselves, it was also a kind of understanding of life.

For ordinary people, there are not many opportunities. Most people spend their lives lying flat.

Su Ran himself began to sigh.

If he hadn't wanted to go home and lie down, and couldn't stand the exploitation of the capitalists in the big cities, the series of events that followed wouldn't have happened.

Therefore, we should live our life in time. No matter what happens in the future or what we encounter now, being happy is the most important thing.

After sending the sea spider away, Su Ran continued to dive into the seabed.

The world in the ocean is always colorful and even magical.

The further we went, the more we encountered a large group of colorful fish. This is the most unique sight in the ocean, a large group of fish swimming together.

Schools of fish swim around on the seabed, like sparkling silver elves.

When Su Ran swam over, all the fish gathered around him.

The sight of the fishes swimming in groups was very beautiful to the audience.

In particular, many people can see schools of fish swimming around in the underwater tunnels of oceanariums or in documentaries related to the deep sea.

So at this moment, many viewers in the live broadcast room were taking screenshots, and some were even marveling at the sight of the schools of fish swimming together.

I'm also a little curious as to why they like to travel in groups so much.

When this question arises, some people immediately hope to get an answer.

As a result, someone in the barrage began to ask Su Ran: "Brother Su, Brother Su, can you tell me why these fish always like to be together?"

"That's right. If there are so many fish together, sharks or whales will swallow them all in one gulp."

"To be honest, I think these fish might be less dangerous if they lived alone, but if they live together in such large numbers, they will easily be noticed by their predators. Wouldn't they be swallowed by them in one gulp?"

Su Ran smiled and responded, "You are not without reason. It's just that biologists generally believe that grouping behavior is an adaptation of fish that has been preserved through long-term natural selection."

"It plays a very beneficial role in the survival of fish."

Su Lan's answer was very different from what the audience had imagined.

"In fact, in biological terms, grouping behavior can not only reduce the probability of forage fish being discovered by predator fish, but also reduce the probability of forage fish that have been discovered being successfully killed by predator fish."

Su Ran dived into the water again, then had a close contact with the school of fish, then returned to the surface and breathed deeply.

"At first glance, a school of thousands or even tens of thousands of fish may be very conspicuous, but in fact, in the vast ocean, a school of fish is no more easily detected by predators than a single fish." "The reason for this has a lot to do with the optical properties of the environment in which the school of fish is located."

Optical properties?
The audience didn't quite understand it, but they always thought it was pretty amazing.

"It's not that I didn't quite understand, Su, could you explain it in more detail?"

Whenever there are people in the live broadcast room who have questions they don’t understand, Su Ran will basically answer them patiently.

So this time he also transformed himself into a professional commentator and said:

“Due to the absorption and scattering of light by suspended particles in seawater, the visible distance of objects in water is very limited. Even in particularly clear water, the maximum visible distance of objects is only about 200 meters.

And this distance has nothing to do with the size of the object. If there are 1000 fish in a school, the probability of one of them being discovered is only one thousandth of the probability of the 1000 fish being found when they are scattered.

It can be seen that the more individuals a school of fish consists of, the smaller the probability of individual fish being discovered. "

After hearing the detailed explanation, the audience also suddenly understood.

During the long process of evolution, small fish in open waters formed groups by following each other and shielding each other in order to cope with the unfavorable environment of the sea where there is a lack of shelter.

When they are attacked, the schools become more dense.

At this time, predatory fish may regard the dense school of small fish as a "giant", so the chance of the small fish being attacked will be greatly reduced.

Although they are in danger, they are safe and sound. For a large number of small fish, traveling in groups can increase the safety factor and ensure their survival and development in an environment where big fish eat small fish.

Therefore, the choices made by organisms are basically for the sake of survival.

Just when everyone was preparing to enjoy the scenery here, there was suddenly a huge noise in the water.

Then the audience saw a scene that shocked them immensely.

A school of winged fish flew out from the bottom of the sea.

The audience at the back of the live broadcast room exclaimed instantly as the hands were typing away on the keyboard.

"It's amazing! This is the first time I've seen a fish flying in the sky."

"I know their name is flying fish, but why don't they swim in the water?"

When Su Ran dived into the water, he discovered that they were being attacked by ferocious swordfish.

Su Ran exclaimed: "This is a powerful guy."

Swordfish can reach a speed of 100 kilometers per hour. Even sharks stay away from it. It is called the ocean catcher.

For example, in the British Museum, there is still a 50-centimeter-thick piece of wooden hull that was pierced by the upper jaw of a swordfish.

So when everyone saw the swordfish, they felt a little panicked.

After all, you really can't underestimate this thing.

An experienced viewer in the live broadcast room directly commented.

"On July 1967, 7, the world's first manned deep-sea submarine explored the Titanic, but during the mission the crew suddenly heard a scraping sound on the hull.

I originally thought that the noise was caused by the submarine scraping against the riverbed, but suddenly I heard a crew member in the right cockpit exclaim: We were hit by a fish.

What you see is a swordfish trying to break free.

Its sharp spike penetrated deeply into the opening of the fairing. So the crew quickly raised the submarine to the surface. "

The audience just heard that this fish could actually pierce the boat with its sharp spines, and they thought it was very powerful. (End of this chapter)
