On the train to Burundi.

Liu Wei: "Gustav is not the largest crocodile ever discovered, it can only be said to be the largest freshwater crocodile, but it is the most famous in the world.

We all know that the Nile crocodile is a brutal crocodile, and its brutal personality is vividly expressed in Gustav, this ferocious personality has brought it a large number of fans, and crocodile fans worship its body, strength, and wildness.

Among the known large crocodiles, Gustav can only rank fourth in size, and the top three predators are all saltwater crocodiles we have seen.

In third place was a saltwater crocodile found in Australia, its name was Dominator, and its body length was 20 feet, and we learned that Gustav's most accurate body length measurement is 19.68 feet, which is a little more than six meters long, which is equivalent to the length of a heavy truck!"

"My day, the picture is shocking!"

"I shuddered unconsciously!"

"A crocodile of more than six meters, I dare not imagine!"

"Monster!"

Liu Wei smiled faintly, and continued, "The second-ranked crocodile, everyone should be familiar with it, it is Luolong, who lives in the Indian National Park, a saltwater crocodile with a body length of 20.3 feet, when catching this crocodile, almost the strength of the whole village was used, but unfortunately it has passed away at the age of 110."

From the analysis of lifespan, the life span of the Nile crocodile can reach 70 to 100 years, in 04, when zoologists studied and observed Gustav, it was only sixty years old, and the body was very healthy, if it was able to escape human hunting and injury, it is possible to still be alive, and now, its age is almost eighty years old!"

"Gu Ye didn't run away!"

"Long live Gu Ye!"

"The absolute force is still alive, if it is dead, it is impossible that no one will find out!"

"What if the bones sink to the bottom of the lake? I remember that Ah Wei also found the fossil of the Australian magic dragon in the lake in Australia at that time!"

"It's not impossible!, but I prefer it to be alive!", Liu Wei smiled, "The number one crocodile is Kalia, a saltwater crocodile with a body length of 23 feet, which also lives in a national park in India, and this crocodile is still alive, so to speak, in the field of human research, its body length has reached the end point of saltwater crocodile growth."

Of course, I hope there are still many predators alive who have not been discovered by humans!"

After speaking, he glanced at the time, "Brothers, I will arrive in the capital of Burundi in ten minutes, and a good friend will come to greet me, he is the famous French zoologist Patters, and the scientist who tried to capture Gustav with a trap for the first time." ”

Burundi Capital Station.

The sound of the train horn gradually subsided.

After parking, Liu Wei came out of the train station with Chubby.

Patters' face is much more vicissitudes than the photos Liu Wei saw on the website.

He was almost sixty years old.

He has reached retirement age, but he still stays in the Luxisi River Basin National Park to study the Nile crocodile.

Liu Wei guessed that maybe it was because of the obsession in his heart that he stayed.

He remained convinced that Gustav was still alive.

"Hey, Liu!Welcome!" Patters walked up and shook hands with Liu.

"Professor Patters, thank you for coming to pick me up!" Liu Wei thanked.

"I would like to welcome zoologists from all over the world to Lake Tanganico in search of Gustav's traces!", Patters smiled gently, "I hope you can bring good luck!"

"Get in the car!"

Liu Wei got into the car.

The conversation between the two gets straight to the point.

When it comes to Gustav and the Nile crocodile, Patus has endless stories to tell.

Liu Wei was curious: "Professor Patters, I have read many authoritative journals, and they all mention that Gustav killed nearly three hundred people in the ten years before he disappeared, is this true?"

Patters held the steering wheel with both hands and said with a faint smile: "I came to Burundi in 1990, and I have been observing Gustav for more than ten years, Liu, I have never heard of it killing so many people."

And, you know, Liu, Burundi is one of the poorest and least populous countries in Africa, with more than 300 people equivalent to the population of several villages around Lake Tanganico combined, and if Gustav had killed so many people, these villages would have been deserted a long time ago, but now they are still widely active in that area!"

"So the news of Gustav's murder is fake?"

Patters shook his head: "The killings are real, but the number is not as exaggerated as the media claims, according to my statistics, Gustav killed a maximum of sixty human beings." ”

"Sixty people is already terrifying!" Liu Wei sighed.

"Yes, Liu, it is very rare for a beast to kill so many humans, so the local residents are very afraid of it, and many people have thought about hunting it, including me.

But that guy is so cunning, our plans all ended in failure!" Patters shook his head with a helpless smile, "If it's alive now, I think I'll do everything I can to protect it!"

Returning ten or twenty years, Patters' current thinking will definitely not be recognized, after all, Gustav is a murderous nightmare and should be punished by humanity.

But now, it's become so precious that it's not just Patters, and if anyone finds it alive, the World Wide Union of Nature will help protect it.

Its place in species like the Nile crocodile is the equivalent of a living fossil.

Liu Wei faced the camera and said, "Brothers, do you know why this Nile crocodile is called Gustav?"

The audience looked confused.

They came to know the murderous Nile crocodile through this name, and almost no one knew the origin of the name.

Liu Weipu said: "Gustav is actually a European family, there are two very famous Gustavs in history, one is King Gustav II of Sweden, interested audiences can go to learn about it."

We focus on the second Gustav, which is the German-made super cannon of World War II - Gustav train gun, which can be described as invincible on the battlefield of World War II.

The country of Burundi was conquered by Germany in the 19th century, and the term Gustav was named by the French ephertologist Patters, a French herpetology expert close to me, who borrowed the prestige of Gustav's train cannon, which actually means the king of crocodiles, the super cannon of the Nile crocodile!"

"Gustav train cannon, I know, a fierce one!"

"In Germany during World War II, the military industry was a real bull!"

"A new knowledge every day, and knowledge is increasing again, hahaha!"

"Thanks to Awei for his popular science, I have the capital to pretend to be forced again!"

Liu Wei continued: "Not only that, but the hypothesis of the cause of Gustav's attack was also put forward by this old expert close to me.

At a time when many people thought that Gustav was a murderous demon, possessed a strong bloodthirstiness, and even regarded humans as prey, Professor Patters made the most consistent assertion of the time with scientific rigor.

Through long-term observation, he concluded that Gustav has a frequent cycle of attacking humans, which happens to be the estrus period of the Nile crocodile, and during the estrus period every year, Gustav will swim around the lake to attract the attention of the female, and at this time, the villagers who come to the lake to wash and fetch water are easy to disturb it, its nose has a special warning sensor, which can detect the pressure generated by the water surface, with the strong territorial awareness of the Nile crocodile, it will take the initiative to drive away the invaders, that is, the villagers who are active near the lake, and finally Gustav will selectively attack these villagers！”
