Chapter 99 The Millennium King 8 Years Turtle?
"Of course not," Chen Fan replied without thinking: "The largest leatherback turtle is only 2.5 meters long and weighs more than 900 kilograms."

"2.5 meters long, that's too big, okay?"

"More than 900 kilograms, this will crush a person to death!"

"You can't think of something better..."

"It's so big, it must be slow to get up, right?"

I don't know who came up with such a sentence.

"Not necessarily."

Chen Fan said with a smile: "Don't look at this leatherback turtle, which is big and bulky, but its limbs are extremely powerful. Not to mention anything else, its crawling speed alone is far faster than ordinary turtles, and don't forget, it is a kind of Sea turtles, living in the sea, can reach a speed of 35 kilometers per hour."

"This, this doesn't seem to be slow?"

"That's right, for our electric car, 40 kilometers per hour is not bad."

"It's quite powerful," Tangyuan became interested, and asked, "The thousand-year-old turtle is 8 years old. Is this leatherback turtle still alive? How old is it?"

"The thousand-year-old tortoise is just a common saying," Chen Fan shrugged, "There are live and long tortoises, such as a 8-kilogram giant tortoise that was once captured by Spanish sailors. Experts estimate that it has lived for 300 years." The lifespan of giant tortoises is about 250 years old. Relevant literature also records: there are some large turtles weighing up to 300 kilograms growing in the Caribbean Sea, and some have lived for 500 years."

"In 1980, someone in South Korea captured a 700-year-old turtle. In China, a live turtle was found under the pillar base of a "Guanlan Pavilion" in Meizhou. According to local records, the turtle was found in A full 240 years have passed under the pillar base, and what is even more exaggerated is that someone in Santai County adopted an old turtle, which was determined by provincial biologists and archaeologists to have lived for 1000 years."

"1000 years!"

Everyone was shocked, even Xia Zichen covered his mouth.

In reality, is there really such a long-lived tortoise?
Chen Fan saw everyone's doubts, and continued: "From these cases, the tortoise is indeed very long-lived. However, there are not many cases with conclusive evidence. There is no effective method to accurately determine the age of the old tortoise. Therefore, some age judgments may lack scientific basis, and the statement that turtles can live for thousands of years is inevitably too exaggerated."

"The average turtle can continue to live without eating or drinking for a month or even several months. Under the condition of food shortage in nature, this extraordinary ability of the turtle also helps to prolong the ecological lifespan. However, the average wild turtle , due to often lack of food, and the threat of diseases or natural enemies, the life span is generally 50 to 70 years, and a few of them exceed 100 years."

"As for the biggest leatherback turtle..."

Chen Fan sighed and said, "I mistakenly thought the plastic was a jellyfish and ate it before I died."

"what!"

Tangyuan felt distressed for a while, and said, "Why is this happening? How could it be?"

"plastic……"

Xia Zichen was also silent.

"Because sea turtles are natural enemies of jellyfish and feed on jellyfish."

"Of the seven existing species of sea turtles, most of them only live in warm waters. This is because turtles are cold-blooded animals, and lower sea water temperatures will affect their body functions. But leatherback turtles have With their own set of temperature-changing abilities, leatherback turtles have rich brown adipose tissue in their bodies, which can carry out efficient non-shivering heat production activities, which is equivalent to adding an electric blanket and insulation layer to their bodies, making them a kind of animal. A rare “mesothermic animal.”

"The so-called mesotherm means that it is neither "cold-blooded" like other reptiles, nor is it constant at a fixed body temperature like our warm-blooded animals. Instead, it keeps its body temperature higher than the outside temperature as the ambient temperature changes. It has been found that The only mesophiles that exist are leatherback turtles, tuna, moonfish and porbeams."

"But this is also at a price. In order to maintain the metabolism required by mesophilia, and to feed such a huge body, the leatherback turtle needs enough food supplements, but it happens to rely on jellyfish, which is not very nutritious, as the main food. Leatherback turtles are required to eat a large amount of jellyfish every day, and some leatherback turtles may prey on 73% of their body weight in jellyfish every day, up to hundreds of kilograms!"

"But leatherback turtles don't have teeth, so how can they eat?" Song Wei scratched his head and said, "Besides, jellyfish are slippery, and the shredded jellyfish is hard to pick up with chopsticks."

"You have a good question."

Chen Fan gave a thumbs up, "Because the leatherback turtle's mouth is full of fleshy spines."

"Spines?"

"It's spines, a little soft. Although it looks very frightening, thanks to the spines, the jellyfish can be bitten smoothly. As long as the jellyfish enters the leatherback's big mouth, it will be hooked by dense spines. In fact , There are many animals that have evolved similar oral structures, such as some penguins. Other sea turtles such as green sea turtles also have spines, but most of them do not grow in the mouth, but grow on the throat wall..."

"So this is ah……"

Several people suddenly realized.

"But Xiaofan, you just said that the leatherback turtle died from eating plastic bags. What happened?" Lao Zhang listened with interest and even asked: "There is a big difference between this plastic bag and jellyfish." ?Can you mistake the leatherback turtle?"

"Yeah, it's too easy to tell!"

"For us humans, it's really easy, but for sea turtles, it's too difficult." Chen Fan shook his head, "We humans are exposed to plastic products all day long, so of course we can distinguish them from jellyfish, but for leatherback turtles , Impossible, once the plastic bag is eaten, it will be entangled with meat thorns, it is impossible to spit it out, and it will eventually lead to indigestion and die."

"Actually, it's not just leatherback turtles. A lot of plastic products have been found in many sea turtle carcasses found by humans."

The atmosphere suddenly fell silent.

"Of course, this is not something we can decide." Chen Fankuan explained: "We can do it ourselves first."

"That's right, Xiaofan, you didn't let us litter the sea two years ago. The sea here in Qingshui Village is relatively clean."

"Yeah, maybe even sea turtles can come to live in our village hahaha."

"All to your house, hahaha."

The atmosphere was no longer as heavy as before, Xia Zichen said with a smile: "Then let's put it away."

"Ah."

"I come!"

Song Wei volunteered, walked up to the leatherback turtle, and said, "Little guy, this sardine is a bargain for you. Don't move. I'll put you back."

As he spoke, he stretched out his hands.

The next moment, the leatherback turtle sprinted and slipped past his feet.

"Hey?"

Song Wei was stunned. Are you sure the tortoise can run this speed?
As soon as he turned around, he attached himself to grab it again.

The leatherback turtle is very flexible, and it is another speed-up to dodge.

"Song Wei, can you do it hahaha, being teased by a turtle?" another young man laughed.

"What are you talking about? I'll catch it later!"

Song Wei felt ashamed, especially in front of the two beauties. At this moment, the leatherback trotted all the way to Chen Fan's feet, put down the sardines in his mouth, and bit Chen Fan's trouser leg.
