My Deep-sea Fishery

"Student Xiang Yang." A professor looked at Xiang Yang, "Please tell me, where is that straight-shelled nautilus."

Xiang Yang frowned! Although the biology expert spoke politely, he had an unquestionable tone, which made Xiang Yang feel a little unhappy.

Although Xiang Yang had already thought in his heart that the straight-shelled nautilus was going to be handed over to this scientific research team, this tone still made Xiang Yang a little angry.

"Old Qian, what are you doing?" Professor Chen Yu felt the change of Xiang Yang's expression very sensitively. Before Xiang Yang could speak, Professor Chen Yu said.

"Dean Chen." The professor named Lao Qian hadn't noticed the change in Xiang Yang, he wondered, "What's wrong with me?"

"Are you a robber?" Professor Chen Yu scolded unceremoniously.

That Professor Qian's expression turned into a pig's liver, and he said quickly: "I'm sorry, Dean Chen, I forgot that he is your student."

"Bullshit." Professor Chen Yu said unceremoniously: "So what if you are my student? What if you are not my student? If you are not my student, you can get someone to take you without even discussing the distribution of benefits." Go get that straight-shelled nautilus?"

Professor Chen Yu is not only a serious scholar, he is also the dean of the Marine Biology and Snow Institute of Ocean University. In his life, he has never been greedy for money, not lustful, and not forming gangs.

He did this not only to help Xiang Yang, but also to cherish his own feathers.

In the past few years, too many so-called experts and professors used the banner of scientific research to confiscate too many treasures from the people, which has already tarnished the reputation of many experts and professors.

Professor Chen Yu cared about his reputation very much. When he saw Xiang Yang frown, he immediately thought of the past when some experts and scholars were greedy for private treasures.

When Professor Qian saw that Xiang Yang was angry, he immediately lowered his head and stopped talking.

Professor Chen Yu snorted coldly, "Scientific research is not a robber. If you take someone else's money, you have to give it back. The annual scientific research funds are originally paid by taxpayers. We can no longer be robbers in front of taxpayers. We should compensate them. Not even a penny less."

Professor Qian nodded quickly.

Professor Chen Yu then looked at Xiang Yang, smiled and said, "Student Xiang Yang, are you sure how many meters is that conch really long?"

Xiang Yang nodded quickly, Xiang Yang was very sure of this.

Xiang Yang knew that Professor Chen Yu wanted to determine whether the conch was a straight-shelled nautilus.

In fact, Xiang Yang has already determined whether the conch is a straight-shelled nautilus.

After discovering the straight-shelled nautilus, Xiang Yang deliberately researched a lot of information related to the straight-shelled nautilus.

In its heyday, the straight-shelled nautilus encountered the strongest competitor is the horseshoe crab.

The straight-shell nautilus and the plate-footed horseshoe crab had a knockout and evolutionary competition in the middle of the Cambrian period.

But until the end of the Cambrian period, the straight-shelled nautilus and the plate-footed horseshoe crab did not completely defeat each other.

The struggle between the straight-shelled nautilus and the plate-footed horseshoe crab has always been the straight-shelled nautilus, which lasted until the end of the Ordovician.

After experiencing the mass extinction event at the end of the Ordovician, the straight-shelled nautilus was seriously injured and eventually lost to the horseshoe crab, but it still maintains a very high position in the ocean.

In the Devonian period, due to the appearance of Dunkleichthys, the sea horseshoe crabs were forced to move to land, and the straight-shelled nautilus could not go ashore. They were oppressed by Dunkleichthys and completely lost their dominance. Finally, the Permian The appearance of the spiral tooth shark made the straight-shelled nautilus family dying. In the Triassic, ichthyosaurs ruled the ocean, and the straight-shelled nautilus was completely extinct.

Nautilus has fought, fought, been brilliant, and also been down, until today, hundreds of millions of years of change, it boiled to death the horseshoe crab, killed most of the prehistoric creatures, and became Like a living fossil.

"Student Xiang Yang, can you take the teacher to see that conch?" Professor Chen Yu asked.

Xiang Yang was about to agree, when Professor Chen Yu spoke again, "We won't let you work for nothing, you just need to lead us to find that conch, whether it is a straight-shell nautilus or not, we will pay you one thousand yuan Remuneration, if it is confirmed that the shell is really a straight-shell nautilus, I can decide to reward you with at least 200,000 yuan, and on the premise of not violating the principle, as long as it is within my ability, you can do whatever you want. Make a request, as long as I can complete it, I will agree to you."

"No, no money." Xiang Yang hurriedly said: "Teacher, you are here for scientific experiments. If you really research something, it is a good thing for the country and the people. I don't think it is good to talk about money. , Anything that is designed in the interest of the motherland cannot be traded."

Professor Chen Yu patted Xiang Yang on the shoulder and said with a smile, "Your awareness is very high, teacher, I am very pleased."

"But teacher, I'm not making a deal with you. The money I give you is a recognition of your practice and a reward."

Xiang Yang looked at Chen Yu.

Chen Yu looked at Haiyang, sighed slightly, and said, "You may not know what a straight-shelled nautilus is."

"Or you don't know its value yet."

"When it comes to nautilus, everyone may think of those ancient creatures that float in the water today. Although they belong to the same category as cephalopods such as squid and octopus, they are extremely lazy. But nautilus have just emerged from the evolutionary tree. When they appeared, there were actually some quite aggressive ones of the same kind, and the most famous of them was the straight-shelled Nautilus that once ruled the ocean."

"This kind of creature that may remind people of the legendary sea monster that once ruled the Ordovician period can be regarded as the hero of the Nautilus, but how did this huge creature disappear?"

"These are secrets. The so-called truth has different opinions, and no one can give an accurate answer."

"At present, the fossils of straight-shelled nautilus are mainly unearthed from the coast of the Baltic Sea, and there are also a large number of small populations that belong to straight-shelled nautilus, but are completely different species. However, it is almost certain that these Straight-shell nautiluses with great differences in body size and size, without exception, are quite fierce predators, especially large nautilus. Their diet includes almost all marine species including other types of straight-shell nautilus. Animals. However, due to the heavy shell of the straight-shell nautilus, their hunting cannot actively chase the prey, but they hunt through an ambush strategy similar to that of an octopus. After the prey approaches, the straight-shell nautilus will rely on the tentacles to pull the prey Catch. Although there were some other predators in the Ordovician oceans in addition to the straight shell nautilus, the straight shell nautilus with their large size makes it very few other types of hunters can threaten them."
