Chen Bin put on a pair of plastic gloves and grabbed the Greenland shark.

Li Xuan also took a step back slightly. To say that parasites are scary is just that, but to say they are not scary is definitely a lie.

As a result, when Chen Bin grabbed the Greenland shark with both hands, everyone, including Chen Bin and Li Xuan, was stunned.

The Greenland shark, which looked like a popsicle, shook its body violently after being picked up by Chen Bin.

Chen Bin was stunned for a moment, and then shouted loudly: "Zhou Cao, this thing is alive."

Li Xuan was also in a daze. The temperature here was very cold. After the fish came out of the water, it immediately looked frozen. Unexpectedly, it didn't die.

"Quickly, throw him into the sea water." Li Xuan reacted and shouted quickly.

Chen Bin was a little reluctant to give up now. He looked at Li Xuan and said: "Brother Xuan, this is alive."

After Li Xuan thought for a moment, he understood what Chen Bin meant.

Chen Bin thinks that live Greenland sharks can be sold for money.

Li Xuan shook his head directly and said: "Throw the alive fish back into the sea. This fish is worthless and no one wants it."

Ever since the field of human science and technology entered the microscopic world, the value of Greenland sharks has really plummeted. Up to now, everyone avoids this thing, just like the god of plague.

This is mainly related to the food of Greenland sharks.

There is plenty of evidence that Greenland sharks will eat any carrion they encounter.

Scientists have also found the partial remains of a variety of fish as well as whales, seals, dogs, horses, reindeer, moose and polar bears in the stomachs of Greenland sharks.

At the same time, the Greenland shark is a slow-moving fish with a low metabolism.

Although humans still don’t know how effective they are as predators, it’s not clear whether they can catch their own food, and it’s also unclear whether they rely on the carcasses of other dead animals to maintain life activities, or whether they can catch food.

prey to eat.

However, so far, no one has ever seen a Greenland shark directly hunting a seal.

Therefore, in terms of biological classification, biologists classify Greenland sharks as scavengers.

As for the organisms that eat carrion, you can imagine the bacteria in their bodies.

When Chen Bin saw what Li Xuan said, he lowered his head and looked at the Greenland shark he was holding in his hand. Then he walked to the side of the boat, threw it down, and then stood on the side of the boat with helpless eyes.

Look under the boat.

Li Xuan was amused when he saw his appearance, "Why, are you still reluctant to part with this shark?"

Chen Bin scratched his head, then nodded and said: "It doesn't matter what parasites or bacteria it is, if it's cooked, nothing will be left. It's such a big fish, and it's still a cold-water fish. Even if you can't sell it for money,

We might as well eat it ourselves."

Li Xuan shook his head seriously and said: "No, your idea is wrong, and it is very dangerous."

Li Xuan doesn't know whether high temperatures can kill bacteria and parasites in Greenland sharks.

But Li Xuan knows that the Greenland shark itself is also poisonous.

Greenland sharks contain large amounts of urea and trimethylamine oxide in their bodies.

These two substances make the meat of Greenland shark inherently toxic.

Many marine fish continuously consume energy to balance the amount of water and salt in their bodies. The high concentration of urea in their body fluids means that water balance can be maintained without consuming energy.

High concentrations of urea are harmful because they destabilize proteins.

In order to eliminate the effects of urea, the body fluids of Greenland sharks also contain trimethylamine oxide.

Trimethylamine oxide itself has other benefits. It acts as an antifreeze and helps Greenland sharks swim in the deep sea.

However, if you eat Greenland shark meat without processing it, you will definitely be poisoned. The harm is similar to extreme alcohol poisoning. If you eat too much, it will lead to death.

Of course, there is no solution to this problem.

Greenland shark meat can be eaten by drying, fermenting or boiling it in boiling water several times until it reaches safe consumption standards.

But Li Xuan would not tell Chen Bin this method.

Because this is just the Greenland shark's own toxins, and Li Xuan can't solve the bacteria and parasites on its body.

Moreover, Li Xuan is very sure that the Greenland shark is a fish that specializes in eating carrion.

Although biological experts have not confirmed whether they can hunt prey on their own.

But Li Xuan himself was very sure that this was not a shark that could hunt on its own.

First of all, most Greenland sharks have parasites in their eyes and are almost blind. Moreover, they live in the dark depths of the ocean, where there is no light. They can only use their excellent sense of smell to find carrion for food.

, they cannot see their prey.

Secondly, Greenland sharks are the slowest swimming species among sharks of similar size. Their normal swimming speed is about thirty centimeters per second, and almost any prey they want to hunt can swim faster than them.

With this kind of swimming speed, in sea water, you can basically say goodbye to hunting on your own.

It is said that the reason why Greenland sharks can live for such a long time is because they swim extremely slowly and consume little, so their metabolism is also slow.

Of course, this is just speculation.

Overall, the Greenland shark can be summed up as an ancient, slow and almost unknown fish.

As a deep-sea fish, the specific number of Greenland sharks is unknown to humans.

But the number of Greenland sharks is definitely not a small number.

Greenland sharks were caught in large numbers by fishermen at the beginning of the last century.

Sometimes the catch in a year exceeds 30,000 fish.

The fact that fishermen can catch them in large numbers reflects that they have a large number of individuals and are easy to catch.

The most amazing thing about the Greenland shark is its age.

Scientists have discovered that crystal structures are left behind in the lenses of Greenland shark eyes.

These crystal structures can be used to determine the age of Greenland sharks using radiocarbon dating.

Using this technology, the longest-lived Greenland shark currently discovered by scientists lived as long as 512 years.

It is absolutely incredible for this age to appear in a vertebrate animal.

Many scientists are trying to find out the real reason why Greenland sharks can live so long.

Some scientists have put forward a theory. He believes that from a genetic point of view, a lower metabolic rate plays a major role.
