"Gillless sharks? Is it the name of this big fish? ”

As soon as Wang Yong's question was finished, everyone around him turned their eyes to Professor Sun. Obviously, this question is also what they are most concerned about at the moment, what is this fish, and why is it so different from the fish that are so common to them?

"Well, this fish is called a frilled shark!"

As soon as Professor Sun's words fell, Guo Qiang couldn't wait to ask:

"Teacher, how do you know? Why haven't I seen this information? ”

Professor Sun looked at his student and did not answer immediately, but looked at the two-meter-long fish in front of him and was silent for a long time. Just when everyone was waiting impatiently, Professor Sun finally spoke.

"There is only one fish found in the world at the end of the 19th century. There are very few records of it, and it's normal that you haven't seen it. ”

Seeing that Professor Sun said these words very plainly, not to mention Guo Qiang and Wang Yong, everyone present could see that there was definitely a story in this!

"Huh? Is that so? So how do you know? Where did you see this? Why haven't I heard you mention it before? ”

Guo Qiang's questioning caused Professor Sun to fall into deep thought again.

He remembers it was when he was just over five years old, and that day he had just returned home from kindergarten with his mother. After a while, an old man hurried to their house and muttered to his parents for a long time.

I don't know what they said, because he was driven back to his room by his mother. Through the unclosed door, he could only see their movements, and as for the sounds, because they had deliberately lowered their voices, he could only hear a few words intermittently.

"Movement, here it is again, information, storage. Please......"

Then the old man was full of tears, and he reluctantly rubbed it on a box he had brought with him for a long time, and finally gritted his teeth and handed it to his father.

He hadn't seen the old man since that day, and his parents had never talked to him about it. However, he secretly opened the contents of the box behind his parents' back.

It's full of books on the ocean, a collection of newspaper clippings about things about the ocean, and even some antique-grade parchment.

And because of this, he has a passion for the ocean. I developed a strong interest in the strange animals and plants in the ocean, and began to collect information on this area since I was a child, and slowly my hobby became a hobby, and finally it became a lifelong career!

Seeing that the teacher was silent, Guo Qiang thought that the teacher had something unspeakable, so he quickly racked his brains to divert the topic and help the teacher get rid of it, but he didn't expect Wang Yong next to him to resolve his embarrassment as soon as he opened his mouth.

"Professor Sun, why is this big fish called a frilled shark? Is he also a shark? Why is it different from the sharks I saw? You look at his tail. And the dorsal fin of sharks is different! ”

Wang Yong's voice woke Professor Sun from his memories, and he looked at his worried students and colleagues, and he smiled reassuringly before crouching down. Little by little, he began to point out the special features of this big fish.

"Look here, this place on either side of the head, three places on one side, and this is its gills! Because he has been living in deep sea waters. Deep-sea environments have low oxygen concentrations, so they need more gill slits to breathe. ”

"And here, see no. This is how the folds come from, and why they are called frilled sharks. ”

With Professor Sun's eloquent and easy-to-understand explanation, everyone listened so intoxicated, and they all had a general understanding of this shark called the frilled shark.

The frilled shark, also known as the eel shark, is so much like a giant eel in appearance. Of course, you can also think of it as a weird-looking deep-sea lizard.

It is a primitive shark with no subspecies, and is known by scientists as a living fossil. It usually feeds on fish and other sharks, but unlike other sharks, it has a unique jaw and needle-like teeth that help him to squid, which is one of his main foods.

This small fish is found in deep waters between 500 and 1,500 meters in the Pacific and Atlantic Oceans, and is ovoviviparous, fertilized in the spring, and hatched for up to a year, with juveniles born the following summer.

This frilled shark, which has hardly mutated in hundreds of millions of years, is extremely rare and can die as quickly as other deep-sea creatures once it surfaces.

"So what's the use of this thing for us? Can you eat it? ”

As for fish, Wang Yong's first feeling at any time is whether it can be eaten or whether it is good or not. So after listening to Professor Sun's introduction to a lot of knowledge about frilled sharks, I couldn't wait to ask the questions I was most concerned about.

"Huh?"

This is a question that Professor Sun is really difficult to answer, because so far, there is only one record of this fish in human history at the end of the 19th century, and there is really too little research and understanding about him.

Seeing Professor Sun's constipation-like expression, Wang Yong quietly slipped away with a lot of eyes. There is such a group of experts who study marine life around them, and they discuss in front of them whether such a precious fish can be eaten?

Without looking at their expressions, Wang Yong also knew that he had said the wrong thing. So it was wise to slip away quietly, leaving a group of them happily engaged in a heated discussion around the big fish.

Wang Yong's only interest in this fish is whether it can be eaten or not, and whether it tastes good or not, so he can't imagine what a sensation such an almost rare fish will cause when it is discovered.

But he soon saw it.

When he and his younger brother Wang Liang were still chasing these little sea crabs that drilled into the sand in a hurry on the beach, a deafening roar came from the sea.

Wang Yong stood up straight and looked at the sea in the distance, a huge helicopter was flying quickly towards where they were.

"Ahh Plane! That's an airplane! ”

"It's strange, why doesn't he have wings?"

Regarding Wang Liang's question, Wang Yong wisely did not open his mouth, because he knew that as long as he opened his mouth, his younger brother, who was at the age of being curious about everything, would definitely become a problem king, and it would be impossible to subdue him without a whole book of "For One Hundred Thousand Whys".

"Brother, what kind of plane is that? How can you fly in the sky without wings? ”

However, Wang Liang didn't seem to have any intention of letting him go, and looked at Wang Yong with his little head very innocent.

"It's a helicopter, with wings overhead, just like the kind of thing you see in the robot cats they can fly with them overhead."

"Huh? Is that really such a thing? ”

"Would you like to buy me one for each one?"

"I want to fly into the sky too?"

"Where is this thing sold?"

"How does it fly?"

Wang Yong's head was three times bigger, looking at his younger brother who was pulling his pants and not reluctant, he had no choice but to make a big move.

"I don't know what you asked, you better ask your parents, they may know. If they don't know, then you can ask......"

Before Wang Yong could finish speaking, he heard a loud sound as a larger and larger propeller cut through the air, mixed with the crisp child's voice of his younger brother Wang Liang.

"He's flying, it's coming! Did he come to pick me up and go to heaven to play? ”

Seeing that the helicopter was obviously coming here, and the altitude was getting lower and lower, Wang Yong was very wise to pull his younger brother to flash people, and if he didn't flash people, it would definitely be asking for his own hardship.

As the height of the helicopter continued to decrease, the strong wind set off by the rotation of the propeller blew the sand and sea water on the beach all over the sky, and the scene was so beautiful that Wang Yong didn't dare to look at it directly!

Fortunately, the helicopter quickly landed on a flat, solid ground by the sea. As the tires came to a steady stop on the ground, the propeller overhead spun slower and slower, knowing that it eventually came to a complete stop.

"Squeak-"

The side hatch was pulled open from the inside, and a soldier in a flight jacket lowered a small ladder, and then five or six men and women of different ages walked down the ladder at once, and ran to Professor Sun not far away without stopping.

"Yo! And journalists? ”

Wang Yong exclaimed, he never expected the reporter to rush over so quickly, and he was also a big-name reporter of CCTV, even Wang Liang, a little thing, recognized the big-name reporter and host who often appeared in CCTV news at a glance.

In addition to him, there was also a reporter with a video camera and a reporter who got off the plane and started taking pictures with a camera hanging on his chest, probably a reporter from the big newspaper, right?

Even the remaining three white-haired old men, looking at the appearance that they are very familiar with Professor Sun, should be experts in this area!

After a few glances, Wang Yong lost any interest in them. Instead, he trotted his younger brother, who had been eager for a long time, to the helicopter that didn't seem to be about to fly away.

"Wow! Brother, it's so big! It's bigger than our big truck! ”

Wang Liang's childish words made the mechanic who came down from the helicopter and was checking the plane roll his eyes very covertly, muttering a few words, but Wang Yong didn't hear what he said.

It's just that the eyes found his contemptuous look, which made Wang Yong's chest immediately ignite the anger of the command. Why, you're a great mechanic? You're not a pilot yet, do you?

"Brother? Can I go up and have a look? ”

Seeing the longing on his younger brother's face, Wang Yong had just sat down in his heart and made a decision, when he was completely angered by a very yin and yang voice next to him.

"Those two children, just say you, stay away, hurry up! Otherwise, don't blame me for pumping you! Get out of here! Come back and don't blame me for being rude! ”

In this regard, Wang Yong didn't even think about it, and began to fight back.

"! You're welcome to give it a try? (To be continued......)
