Unexpected animal common sense

1. What are the unexpected animal disasters?

Cat Disaster in Marivan Island Marivan is an island in the Indian Ocean. 1945, the first expedition from South Africa came here, and a few mice came ashore secretly. At 1948, mice became the overlord of the island. The expedition brought five cats to catch mice, but seabirds were more delicious than mice. Cats eat birds instead of catching mice, and as a result, cats breed to 25,000. Eat 600 thousand snails a year. Snail Disaster in Hawaii In the 1930s, some businessmen transported African snails to the Hawaiian Islands for human cultivation and food. Some snails are too old to eat, so they are thrown into the wild. In less than a few years, snails breed everywhere and eat vegetables and fruits indiscriminately. People spray chemicals. Land that has been continuously cultivated 15 years cannot be cleared. Washington state goldfish disaster Americans have long imported goldfish from Japan. 1973, some goldfish in Washington state accidentally fell into the water and then multiplied. A few years later, goldfish occupied 10 lakes. Trout in the lake can't get food from goldfish, so the yield is greatly reduced. Fishermen complain that fishermen can't kill goldfish. Spanish crab disaster 1976. Spain imported 50,000 crab seedlings from the United States and raised them in a river delta. A few years later, they have multiplied to hundreds of millions, and the local area can only catch up to 4 million for human consumption every year. The water in the rice field leaked out along the dense crab holes. Crabs eat fish and shrimp, aquatic plants, plankton, rice seedlings, fish are gone, birds have nothing to eat, and they are not staying here.

Animals have brought unexpected disasters to human beings.

65438+February 26th, 2004 is Black Christmas. A strong earthquake in Southeast Asia triggered a tsunami, causing heavy casualties to Indonesia, Sri Lanka, Thailand, India, Malaysia and other countries along the Indian Ocean. However, a phenomenon has attracted people's attention, that is, in this huge tsunami disaster, animals survived. Yala National Wildlife Park in Sri Lanka is one of the areas hardest hit by the tsunami. Many tourists on the island were killed in the tsunami, but it is hard to understand that almost no animal carcasses were found. Park managers said that animals have the function of sensing disasters, so they can escape before disasters happen. Yala National Wildlife Park is the largest wildlife reserve in Sri Lanka. There are about 200 Asian elephants in the park, as well as a large number of wild boar, buffalo, apes, crocodiles and other animals. In addition, there are the largest number of leopards in Asia. When the tsunami struck, the sea washed away the buildings in the park, killing about 200 people, including about 40 foreign tourists. Unexpectedly, all kinds of wild animals in the park are safe and sound. When the deputy director of the park met the reporter, it was incredible. Not even the body of a rabbit was found. This shows that animals can perceive disasters and know when they will happen. According to the photos taken by the Air Force by helicopter to Yala National Wildlife Park, the surging sea water poured into the park. Although elephants, buffaloes and deer can be seen, no signs of death have been found in these animals. The staff of Yala National Wildlife Park also confirmed that only human remains were found after the tsunami. No dead animals were found. They think that these animals may have predicted the coming disaster. The researchers pointed out that animals do not have the so-called "sixth sense" to predict disasters, but their hearing or some senses are more sensitive. French researchers believe that some social animals also have efficient "alarm codes", that is, they can make special noises before discovering disasters to remind their companions to escape from disasters. Researchers say that with the progress of science and technology and human beings,

3. What are the unexpected giant animals in the world?

This lobster is about 0.76 meters long. It is estimated that he is at least 60 years old.

British fishermen caught a rare giant lobster in the waters near Dorset, England. This lobster has a pair of giant pliers and its body is about 0.76 meters long. It is estimated that he is at least 60 years old.

Lobsters have a pair of giant pliers that can hold coke cans.

Local fishermen said that they have been fishing for lobsters for several years and rarely see such huge lobsters. The fisherman also smiled and said, "Because of its huge size, it is not suitable for cooking, so this lobster saved his life."

It is said that the normal weight of lobster is directly proportional to its price, but because lobster meat exceeding a certain weight is not delicious, oversized lobster is not popular in restaurants.

Underwater photographer Daniel photographed a giant mola fish in San Diego, California, USA, with a strange shape.

Giant squid

This giant squid lives in the dark deep sea of the Pacific Ocean, and little is known about it. There was a legend that this squid would "sit" on the bottom of the sea, extend its tentacles to the sea and attack ships. Legends are legends after all. Actually, this creature is not small. It can grow to 18 meters long and weigh 900 kilograms.

sperm whale

Sperm whales are the largest toothed whales, and adult whales can be as long as 18 meters.

killer whale

Black whales have a big appetite. Besides fish, even seals and sharks are their delicacies. They can drag seals off the ice, and sometimes even seabirds can't escape.

The restaurant bought a giant grouper weighing 509 Jin.

There is a giant grouper weighing 509 Jin in a seafood restaurant in Houjie, Dongguan. This fish was bought by the restaurant owner and returned by air. It is about 2 meters long and weighs 509 Jin. If it is sold to the museum as a specimen, it will be worth100000 yuan.

The crocodile captured alive by Filipino residents is 6.4 meters long and weighs more than 1 ton.

In Shawn Ku Province, South Philippines, four men measured the length of saltwater crocodiles with their arms. According to the Palawan Wildlife Rescue and Protection Center, this 6.4-meter-long saltwater crocodile weighs 1.075 kg, making it the largest crocodile ever captured in the Philippines.

4. Composition: People and animals should be unexpected.

Motherly love, love beyond life

A medical experiment I have done is to do a drug toxicity test with adult mice. In a group of mice, a female mouse had a lump the size of mung bean at the root of her armpit and was eliminated. I want to know the properties of the blocks, so I put them in a plastic box and keep them separately. Ten days later, the longer and bigger the lump, the bigger the abdomen of the mouse, and the activity is very difficult. I conclude that this is the result of ascites caused by tumor metastasis.

One day, I suddenly found that the mouse didn't eat or drink and was fidgeting. I think that mouse has probably finished its life, so it turned to get a scalpel, ready to dissect it, and take some fresh tumor tissue for culture and observation. Just as I opened the surgical bag, I was stunned by what I saw.

The mouse turned its head with difficulty, bit the big toe-sized lump, yanked it, and the skin cracked and blood gurgled out, making the mouse tremble with pain, which made people shudder. Later, it swallowed the lump that killed it, and every bite was accompanied by a spasm of the body. In this way, more than half of the lump was bitten and swallowed. I was deeply moved by the mouse's spirit of longing for life and the way to survive, and put away the scalpel.

The next morning, I hurried to see if it was still alive. To my surprise, there were a bunch of pink mice lying under the mice, sucking their milk desperately. I counted ten.

The wound of the mouse has stopped bleeding, and the lump has been stripped off under the armpit of the left forelimb, revealing the bones, which is terrible. However, the spirit of the mice improved obviously and their activities increased.

Malignant tumor is still torturing mice mercilessly. I am really worried about these poor little things. Once their mother leaves, they will starve to death in a few days.

Since then, the first thing every day is to come to the mouse box and look at them.

It is really unpleasant to watch ten growing offspring suck the milk of a terminally ill and scrawny female mouse. I know why the mother mouse has been trying to prolong her life. But in any case, it may die at any time.

This day has finally arrived. On the morning of the 2nd1day after giving birth to offspring, the mice lay motionless in the middle of the mouse box. Ten young rats surrounded the area.

It suddenly occurred to me that the weaning period of mice was 2 1 day. In other words, from today, future generations can live independently without drinking their mothers' milk.

In the face of this scene, I burst into tears.
