In the vast depths of the ocean, there are many species of creatures in various shapes and forms.

The diversity of these organisms is amazing, and they each play a unique role in the marine ecosystem.

However, for many netizens, facing such a large number of marine life, they often feel overwhelmed.

It's just that many of these creatures are not of particular interest to them.

But creatures like sea urchins are well known for their unique appearance and biological characteristics.

Kelp, as an important plant in the ocean, also occupies a place in people's marine knowledge system.

For people who do not live in coastal areas, sea urchins and kelp have almost become their basic knowledge of oceanography. These two things are indispensable in any marine environment.

They were so familiar with the image of the sea urchin that they could almost imagine what it looked like, as if the sea urchins were about to pop out of their eyes.

"Brother Su is here now. It's good to catch some fish, but shouldn't we catch some sea urchins?"

"I'm telling you, sea urchins are very valuable. We have to make a fortune out of them. We can't miss this great opportunity."

What the audience said made sense, and Su Ran also wanted to get some sea urchins to satisfy his craving.

Since everyone said so, he would definitely go and look for it.

As he continued to move forward, suddenly, he felt a strong current of water rushing from the front.

He looked up and saw a slightly larger fish swimming towards him.

Why do we say that its size is only slightly larger?

Because compared with those real sea monsters, its size is not particularly large.

However, compared with the small fish around it, it appears abnormally huge, as if it is the overlord of the ocean.

When the fish swam in front of the camera, Su Ran was surprised to find that it was a shark.

The audience's heartbeats suddenly accelerated, and an unknown fear spread in their hearts.

"Oh my god, it's a shark! Brother Su, you better be careful, don't get swallowed by it!"

The audience was extremely shocked when they saw this scene.

Sharks, as one of the most ferocious fish in the ocean, undoubtedly added many unknown dangers to this expedition.

If he meets someone, he will swallow them in one gulp.

However, Su Ran was very calm, neither panicked nor hurried.

This shark is small in size and is considered to be a relatively gentle species.

Unlike other great white sharks and other ferocious sharks, it has a relatively gentle personality.

Humans use tools, and clever fish use humans.

It was obvious that the shark had no ill intentions when it came over. Instead, it was very greedy for the big fish that Su Ran had just caught.

Its eyes were fixed on the big fish, as if it was thinking about how to get it into its stomach.

Good guy.

I understand, is it attracted by my fish?

Then I'll give it to you to eat.

Su Ran knew in his heart that he was in someone else's territory at the moment. If he didn't satisfy the ruler here, what if he got so hungry that he ate him directly?

Therefore, he threw the fish in his hand to the other party without hesitation.

The fish gently drew an arc in the water. In this vast body of water, it looked so small, as if it was a speck of dust in the ocean.

However, for sharks, it is a delicious meal.

The shark seemed to have noticed this as well, and its huge body swam flexibly in the sea.

Suddenly, it shook its tail fin violently, and then rushed towards the fish quickly. In an instant, the shark opened its bloody mouth and swallowed the fish directly into its mouth.

This scene made the audience in the live broadcast room sigh at the cruelty of nature and the fragility of life.

Amid the sighs, the shark seemed unusually excited.

It seemed as if it suddenly lived the life of free food and drink that it had always dreamed of.

Especially when the shark looked at Su Ran again, its eyes seemed to be asking, "Anything else?"

Viewers couldn't help but be amazed to see a fawning expression on a shark's face.

"It turns out that there is more than one beggar in the wild who is a celebrity wolf," someone joked.

"This shark is so interesting," another person agreed.

"Okay, so we're just going to eat and drink for free, right?" The audience discussed in a sardonic manner.

After eating and drinking, the shark suddenly swam away. Su Ran thought it was going home to take a nap.

Unexpectedly, he brought his own tribe here soon after.

Introduce them to Su Ran one by one.

A group of sharks were whispering to each other, but no one knew what they were discussing.

But it seems like he's probably saying: This is the guy who's fishing here, right?
This group of sharks does look like they are not easy to deal with, but they only eat fish and do not attack humans.

After all, you can still distinguish between one meal being full and another meal being full.

A shark is eaten in one bite.

The fish that Su Ran had caught with such great difficulty were all gone in an instant.

No, you don’t know how to catch it yourself!
Su Ran felt a little dizzy.

But he found it quite interesting.

Anyway, it's just eating fish, it will only make you a little tired, as long as you don't eat it.

So Su Ran began to look for other fish around, and then fed all the fish to the shark family.

Su Ran always felt that when he fed them, these guys were like puppies, which was quite interesting.

After the sharks became familiar with Su Ran, they felt that they could not eat for free, and some small sharks even gave their shaved teeth to Su Ran as currency.

This was the first time Su Ran had seen shark teeth. They were triangular in shape, and very different from human teeth.

As a result, Su Ran inexplicably had a lot of shark teeth in his hands.

The audience was extremely surprised.

"Oh my god, if you give it so much at once, doesn't it need teeth of its own?"

"I'm so scared that these sharks will give away their teeth and then they won't have any more to use, haha."

The audience sent out barrages of comments.

Su Ran couldn't speak now, he definitely knew that these teeth were nothing to the shark.

Fortunately, Deng Jiaying explained in the live broadcast room: "Don't worry, shark teeth are very different from shark fins. According to records, sharks can replace about 20000 teeth in their lifetime. Strictly speaking, what is replaced is not teeth, but scales."

As a cartilaginous fish, all the bones in the shark's body are made of cartilage, and there is no true bone tissue. After the exoskeleton degenerates, the body is covered with dermal teeth, or scales.

After research, scientists concluded that the scales on sharks are very similar to the structure of teeth.

It can even be said that shark teeth are a derivative of body scales, which also explains why sharks can replace their teeth frequently. After all, the scales of many fish are replaced regularly.

So these teeth are nothing to them. (End of this chapter)
