If such a thing happened on land, it would almost be a fantasy.
But in the ocean, it is a very real possibility.
The vast ocean is home to countless incredible lives.
Xiang Yang once read a news report that said a little boy who loved seafood had two one-meter-long parasites on his back. The parasites also came from the ocean.
After burning the hagfish to death with gasoline, spraying disinfectant on anyone who approached the hagfish, and finally washing the deck with alcohol, Xiang Yang did not allow the crew on the ship to fish anymore.
The crew on the ship had no complaints.
In fact, even if Xiang Yangzun asked the crew to fish, they would not do so.
Not to mention sea fishing, many crew members didn't even dare to approach the edge of the deck after listening carefully to Xiang Yang's description of the horror of the hagfish.
Are you kidding? It can survive by starving for half a year, can parasitize in the human body, and can eat twice its own body weight in food every day. If you are parasitized by such a terrible parasite, you will be bitten to death by it.
Xiang Yang found it funny, so he said, "Actually, you don't have to be so afraid of hagfish."
"How can I not be afraid? When I think about the possibility of such a terrible thing in my body, I can't help but shiver all over." Fang Youqun said with a trembling heart.
"But it's not so easy for hagfish to parasitize the human body. Don't worry, as long as you don't eat raw seafood, there will be no parasites in your body." Xiang Yang said with a smile.
High temperatures can kill most marine parasites, including hagfish.
Many people like to eat seafood raw, especially seafood like salmon, which tastes better when eaten as sashimi.
But Xiang Yang never eats raw seafood. He cooks all seafood before eating it, even the most acceptable drunken shrimp.
After Xiang Yang finished speaking, he thought everyone would breathe a sigh of relief.
However, Xiang Yang discovered that after he finished speaking, the expressions on many people's faces instantly became uglier.
Xiang Yang was quite puzzled and asked: "Why do you all have such expressions?"
"Brother Yang, I've eaten raw seafood." Fang Youqun said with a bitter face.
Xiang Yang blinked his eyes. "When I let you eat seafood on weekdays, isn't it always cooked?"
"But we have eaten raw food ourselves." Fang Youqun said bitterly.
Xiang Yang covered his forehead and said after a while: "Just eat it. It's not a big problem. For example, among the fishermen of my father's generation, there are several who have never eaten raw seafood, but they are still not infected by parasites, right?"
In fact, even Xiang Yang himself had eaten raw seafood before.
When Xiang Yang was a child, he also ate raw oysters.
In order to prevent panic from spreading on the ship, Xiang Yang decided to quickly disclose the matter.
Xiang Yang glanced left and right, finally landing on Xu Fang.
"Xia Pengjie, there is no wind or snow on the sea now, you don't have to wear a windbreaker and snow pants on the boat, right?" Xiang Yang said to Xia Pengjie, who was fully armed, still hunched over with his hands inserted into the sleeves of each hand.
Now is the time when the sun is the brightest in the day. Although the temperature in Antarctica is low, Xiang Yang himself feels a little cold, but it is definitely not cold enough to need to wear a combat suit.
"You all went underwater to exercise just now, but I stayed on the boat without moving. Of course I am colder than you." Xia Pengjie said, stamping his feet. The cold weather made his feet hurt.
"Shouldn't it be us who go under the water and be colder than you?" Fang Youqun asked, tilting his head.
"You weren't wet by the sea water, and you've been exercising for so long, how could you be colder than me?" Xia Pengjie rolled his eyes.
As the saying goes, life lies in movement.
Many people have the habit of exercising in winter.
Often when it’s cold, I just run around the playground a few times and I won’t feel cold anymore.
Of course, this situation is limited to the south in our country.
In the north, the outdoor temperature is really too low, and it is not suitable to go out in winter.
Antarctica is a place much colder than the north of our country and is the coldest continent in the world.
The average annual temperature in Antarctica is minus 25 degrees Celsius, and the average annual temperature in inland areas reaches minus 40 to minus 50 degrees Celsius.
In 1983, the temperature even reached an incredible low of minus 90 degrees Celsius.
Scientists have different opinions on why Antarctica has such cold weather. After all, Antarctica actually has a lot of sunlight, and sometimes even has polar day.
The most common explanation for why Antarctica is so cold is that the Earth is rotating all the time and also revolving around the Sun. The sunlight comes from far away, and the Earth's belt, which is near the equator, is directly exposed to the sunlight, so the average temperature at the equator is relatively high.
The head and foot of the earth, that is, the South Pole and the North Pole, can only be illuminated by sunlight obliquely, and there are even long periods of time in a year when the sun cannot be seen. The amount of light received is relatively much less. Due to the lack of sunlight at the South Pole and the North Pole, the temperature is of course lower.
Moreover, Antarctica is located at the southernmost tip of the earth and is an area covered with ice and snow. Because it is covered by thick ice, the ice reflects sunlight back to the sky, so the polar region has a weak ability to retain heat, making it even colder.
However, this statement is somewhat controversial.
Because the North and South Poles, both poles, receive the same amount of sunlight, but the coldest place is at the South Pole, not the North Pole.
Some scientists believe that although the North and South Poles are both the poles of the earth, their terrains are different and their heat dissipation rates are also different.
The Antarctic region is a landmass called Antarctica, while the Arctic region is a sea called the Arctic Ocean.
There is a big difference between seawater and land in absorbing heat. When exposed to the same light, the temperature of land rises faster than that of seawater.
Without sunlight, the land would cool faster.
When the sun shines on the poles in the summer, the Arctic Ocean slowly absorbs heat, and in the winter it slowly releases heat, so the temperature in the Arctic is not that cold, while the heat dissipation rate in Antarctica is very fast.
Even if there is polar day in Antarctica, the sunlight can still provide a lot of temperature.
However, because Antarctica dissipates heat quickly and has a poor ability to retain heat, no matter how much heat the sun shines on Antarctica, it will quickly be dispersed by Antarctica, so the temperature in Antarctica is much lower than that in the Arctic.
Xiang Yang personally agrees with this statement.
The low temperature in Antarctica is not just due to the lack of sunlight, but also due to the rapid heat dissipation in Antarctica itself.
