A jewelry store in San Francisco, USA, was repeatedly stolen by thieves. The shopkeeper ingeniously put several big poisonous spiders in the window and wrote a notice on it: "There are poisonous spiders guarding the shop at night, be careful!" " Cough and cough really worked, so that the gentlemen on the beam stopped watching, and the jewelry in the store was safe from now on.

The poisonous spider in the temple

A British geological survey team walked in the subtropical jungle in western Myanmar for three days and nights. The team consists of eight people, most of whom are young geologists. Everything here is full of mysterious colors, and they feel very fresh.

Captain Cole is an experienced veteran. He walked all the way, talking and laughing with the players, trying to make everyone forget the fatigue of the journey. They are accompanied by a dog named Charlie.

On this day, they climbed several mountains in succession and came to a deep mountain in the evening. They must find a safer place to spend the night before dark.

At this time, a team member found a building not far ahead, and everyone suddenly came to the spirit and gathered strength to move on.

After climbing a hillside, the team saw a dilapidated temple, hidden in a large area of weeds and trees.

The players walked past with great curiosity. This is an abandoned temple for a long time. The brick wall was riddled with wind and rain and almost collapsed. The towering column at the top of the tower broke in two. The door tilted to one side and the monks had long since disappeared. It's very quiet around, showing a mysterious atmosphere.

Captain Cole led Charlie ahead. He growled with suspicion in his voice.

Cole saw a whitewashed word on the wall facing him, which was written in Burmese, so he asked a player who knew a little Burmese. He guessed and said roughly: "there are demons in the temple, and those who enter the temple die."

The team members got nervous and followed the captain to the temple.

Suddenly, there was a loud noise overhead, which startled everyone. Looking up, it turned out to be a big owl. Obviously, the arrival of these unexpected guests disturbed its dream, and the owl flew away in panic.

Everyone continued to walk inside, and a rancid smell came to the nose. Charlie looked a little restless, and Cole had a premonition that something might happen so that everyone could pay attention.

Just then, there was a loud bang, and then a cloud of gray fog rose, and a large piece of lime fell from the wall. Charlie growled. Through the fog, everyone saw a snake with thick thighs and a rabbit in its mouth, slowly crawling out of the hole where lime fell from the wall.

The players couldn't help but take a few steps back, but the serpent didn't mean to invade people. It turned its head and climbed to the dark temple nave.

There are many staggered Buddha statues in the middle hall, with a shrine in the middle. The temple is covered with cobwebs. This kind of spider silk is unusual and very thick.

They searched along the spider silk with flashlights and found a very strange spider behind the shrine. Its body is two inches long. The whole body is dark red, the legs are very long, and there is a long and pointed needle at the tail.

Probably the light of the flashlight alarmed it, and it turned around with difficulty. Because it is full of brains and intestines, it seems very inconvenient to move.

At this time, the serpent has climbed behind the shrine. It straightened its neck and looked up, then climbed up along a rotten wood pillar next to the shrine.

The spider found the snake crawling towards it and turned around again.

Then, something strange happened. The snake slowly brought the hare in its mouth to the spider.

The rabbit was killed by a big snake, but it trembled violently as soon as it touched the spider silk, as if it had touched the power grid and died.

Okumo stuck the tail needle into the rabbit's head, slowly sucked its brain juice, then pulled out the needle, pierced the rabbit's back and continued to suck its blood.

In a blink of an eye, the juice on the rabbit has been completely sucked dry, leaving only a skeleton.

When the serpent saw that the spider had eaten enough, he took down the dead rabbit like an empty skin, slowly climbed down the shrine and got into the hole in the wall.

This strange scene fascinated the players. At the moment, this Okumo's body seems to have doubled, and it is glowing all over.

Everyone is sick of this strange spider and wants to kill it. But Cole thinks this is an extremely rare spider, which can be made into specimens for biologists to study.

Blackarachnia

The back door of the canteen of Shanghai Refractory Factory is dark and damp. There is a bucket by the door, where employees often go to pour leftovers and wash dishes and chopsticks. Although this place is not noticed by people, a natural wonder appeared not long ago.

This morning, Jamlom, a young worker, was washing rice in a bucket. Occasionally, I looked up and saw a purple bug about 15 cm long on the wall, which was quickly climbing to the root of the wall.

"Big centipede!" Jamlom exclaimed that several young workers passing by were surrounded by the sound. Jamlom picked up a brick from the ground and was about to kill the centipede, only to see its body covered with many thin feet suddenly stopped.

It's strange. I looked carefully, and it turned out that a spider smaller than mung bean stood in front of the big centipede. The two sides kept a certain distance and confronted each other. Four or five seconds later, the big centipede suddenly pounced on the little spider. The little spider flashed cleverly, and the big centipede jumped into the air, turned around and descended again. This time, the little spider has circled around the big centipede and jumped lightly on the head of the big centipede. The centipede sticks out its head and opens its mouth, but it can't bite its opponent.

The little spider took the opportunity to spin silk on the head of the big centipede, wrapped wisps of spider silk around the antenna on the left side of the big centipede, then gently jumped down and climbed into the corner to hold the spider silk hard. The centipede left the ground. Then the little spider came down along the edge of the silk, then spit out a silk and wrapped it around the antenna on the right side of the centipede, climbed to the corner and glued the silk to the wall and slowly recovered it. In this way, two invisible fine spider silk hanging centipedes like goods! No matter how the centipede shakes its body, it can't escape the entanglement of spider silk.

At this time, the big centipede has become the "death row" of the little spider. At this time, the little spider easily jumped on the head of the "death row" and stabbed a pair of needles in his mouth into his body. This sting contains a lot of toxins. Soon, the centipede twitched a few times and died.

The little spider greedily sucked the juice of the centipede, had a full meal and waddled back to the corner.

The people present witnessed this extraordinary battle and were amazed: examples of the weak defeating the strong abound in nature! An interesting story about sharks.

Sacrifice crocodiles with living people

A 8.24-meter-long, 2-ton fish was found in the northern part of Queensland, Australia, and a group of indigenous people who took Shoupin fish as their gods and made human offerings were also found, with as many victims as 100.

This terrible murder was committed by a victim's brother. One day, the elder brother witnessed his sister being kidnapped by several men in broad daylight. He followed him to a swamp in the forest. He saw these people push his sister into a dry swamp and then walk into the forest.

He also continued to follow and found Yingkou where they lived. He immediately ran back to the city to call the police for help. When the police arrived at the swamp, they found giant crocodiles and countless human remains in the swamp. The police immediately launched a large-scale operation to arrest indigenous people, arresting a total of 30 indigenous people, but their leader and at least 25 people are still at large. The police sent two fishing experts to the scene to catch giant crocodiles and check their bones. According to preliminary examination, at least 100 people were injured. It is believed that these victims were not accidentally thrown into the swamp, but were pushed into the swamp as sacrifices by indigenous people. The police are now stepping up their efforts to hunt down the leaders of indigenous people and prevent them from using another crocodile as a god to harm the world.

Sharks save lives

Rosalyn is a student at Florida State University.

On Christmas 1985, Rosalyn and two classmates went to Markkula Island, west of Fiji in the South Pacific. On the way back to Fiji, after the ship had been driving for half an hour, suddenly someone in the bottom cabin shouted, "The ship is leaking!" " "Suddenly the ship was in chaos. Rosalyn quickly put on her life jacket and climbed into the lifeboat with two classmates. At this time, there are 18 people on board. Due to the large number of people and uncoordinated movements, the boat shook badly and was in danger of capsizing at any time. The ship bumped in the waves for 2 ~ 3 hours, and a line of land appeared in the distance. Bold Rosalyn jumped into the sea and shouted, "It's not far from the land, swim boldly with me. "But because the waves are too big to play her swimming level, she can only go with the flow. At the critical moment, she suddenly found a big block of wood, so she grabbed it and was dragged by the block to drift on the sea.

She drifted for several hours, when the sun was setting on the sea, and she found another dark forest drifting towards her quickly. When she walked to the front, she saw that it was a shark 2-3 meters long! With a black back, a silver-gray belly and teeth shining in the moonlight, she thought she would be eaten by a shark.

The shark slammed into her, then opened its mouth and bit her life jacket, tearing it to pieces. Then two sharks, one caught in the middle, pushed her forward with their heads. It was like this all night. At dawn, Rosalyn appeared around two sharks. Four or five sharks tried to rush over and eat her with their mouths open, but they drove her away.

At noon the next day, a shark suddenly swam away and came back after a while. Rosalyn saw a small fish floating in front of her. It turned out that the shark prepared lunch for her. She was so hungry that she grabbed the little fish and ate it.

When dusk came to the sea again, a rescue helicopter rescued Rosalyn. She wanted to see the two life-saving sharks again in mid-air, but they had disappeared without a trace.

People don't believe that fierce sharks will save people, but it's true.

Mystery of shark anti-cancer

Today, cancer is still one of the main diseases threatening human life, and scientists have not yet found a specific drug to treat cancer. Therefore, the search for anticancer drugs has become an insurmountable fortress in science.

Biologists have found that sharks are very healthy. Even if they have suffered great trauma, they can recover quickly, and there is no inflammation at all, let alone infection.

Ruhr, a famous American biochemist, works in the world-famous Matt Marine Laboratory. He has made a long-term study on the physiology and pathology of sharks. In the past 25 years, he has done pathological anatomy research on 5,000 sharks, and only one shark has a tumor, and it is also a benign tumor.

According to the data of the National Registry of Lower Animal Tumors, 16 sharks have the least cancer. Ruhr also found that out of more than 25,000 sharks investigated by scientists, only five had tumors. This discovery of Ruhr aroused great interest of scientists in sharks, and scientists all over the world began to study sharks.

Scientists in Florida used to feed sharks with aflatoxin, which is a very strong carcinogen. In the feeding experiment of nearly 8 years, no shark has grown a tumor. It can be seen that sharks have strong anti-cancer ability. So, what is its anti-cancer trick?

Some scientists believe that the secret of shark's anti-cancer lies in that it can produce a chemical in muscle. This chemical can inhibit the growth of cancer cells, so it is not easy to get cancer.

Dr. Ruhr believes that shark's liver can produce a lot of vitamin A. Experiments have proved that vitamin A can differentiate epithelial cells that have just started to become cancerous and restore them to normal cells. So Ruhr thinks that the secret weapon to protect sharks from cancer is vitamin A.

Other scientists believe that shark blood can produce an anticancer substance. Scientists from Shanghai Fisheries College in China also support this view. 1984, they extracted blood from the shark's heart, then extracted a certain concentration of serum and injected it into human erythroleukemia cells (a kind of blood system cancer). After a period of time, they found that the normal metabolism of some cancer cells was destroyed and most of them had died. This shows that shark serum has the effect of killing human erythroleukemia tumor cells. It can be seen that there are anticancer substances in the blood of sharks.

Some scientists believe that there are secret weapons in shark cartilage. Once upon a time, scientists found that calf cartilage had a certain anti-cancer effect. 1982, Langer, a scientist at the Massachusetts Institute of Technology, found in his research that shark bones are all made of cartilage. There is a compound in these cartilage tissues that can block the vascular network around cancer. "It can cut off the supply of cancer cells, shrink cancer cells and kill cancer cells at the same time. He confirmed through experiments that this substance in shark cartilage can completely stop the growth of cancer cells without any side effects, and its anticancer effect is 65438+ million times stronger than that in calf cartilage.

Scientists at Harvard University tried to treat 32 patients with advanced cancer with shark cartilage extract. Results 28 cases were cured, and the rest cancers were obviously relieved.

199 1 year, 8 patients with advanced cancer were treated with shark cartilage extract, and their cancer cells were reduced by 30%- 100% in different degrees.

Molecular biologist Zaslov believes that shark's anti-cancer weapon is in the stomach. In his experimental research, he found that the shark's stomach can secrete an antibiotic called canthaxanthin, which has a stronger bactericidal effect than penicillin. It can also kill protozoa and fungi at the same time, as well as resist AIDS and cancer.

The conclusions are really varied.

What is the secret weapon of shark's anti-cancer is still a mystery. I believe that when this mystery is solved, it is the day when human beings send away the cancer plague.

white shark

Sharks are called "siren", and fishermen or sailors are talking about shark discoloration. Among sharks, the most powerful is the man-eating shark. Man-eating shark, also known as great white shark, is a giant among sharks.

1989 65438+1On October 28th, a female corpse floated with the waves in the sea not far north of Los Angeles, USA. The female corpse was scarred, and the width of only one wound in the leg reached 33 cm. People soon discovered her identity. Her name is mana McCartney, 24, and she is a graduate student at UCLA. Four days ago, she went to sea with her boyfriend stoddard in a rubber boat, and then she disappeared. According to the situation of the deceased and the location of the accident, people judged that they had met a great white shark.

Like this, the news that great white sharks eat people is endless. When it comes to great white sharks, people shudder and call it "white death".

Great white sharks are generally about 7 meters long, up to 12 meters long and weighing about 1800 kg. Great white shark belongs to cartilaginous fish, which is muscular and powerful. Its sense of smell is particularly sensitive, especially for the smell of blood, which can be smelled from far away. The most daunting thing is its sharp teeth. The edge of each tooth has small serrations. These teeth are arranged in rows in the mouth, up to 7 rows, with more than 654.38+0.5 million teeth. In addition, its body surface is covered with numerous sharp scales, each of which is like a row of sharp blades. As long as it is rubbed on people, a large piece of meat will be scraped off.

What people want to know now is, why do great white sharks attack people? Marine zoologists believe that great white sharks are very fierce, but rarely attack people. According to statistics, among the hundreds of millions of people swimming in the sea every year, only one in five million is attacked by great white sharks, and 80% of them are only slightly injured. But why does it attack people? Some people think that it is purely a misjudgment. They mistake people who fall into the water or swim in the sea for seals or sea lions. Others think that great white sharks will attack people, which may be a warning to those who break into their territory. Some people think that the attack of great white sharks on people may be caused by the destruction of some balance mechanism in their bodies.

It has also been found that the great white shark as fierce as the devil is actually afraid of orange. Just put an orange board next to the great white shark and it will disappear immediately. What's going on here?

Great white sharks are fierce and like to live alone, which are widely distributed in most of the world's oceans, which brings great difficulties to the research work, and people have not yet figured out their population.
