There is a king squid in the squid family. Just like its name, it is a giant. Its body length is 18 m, its long legs are 1 1 m, and its weight is 30,000 kg. This? King of squid? I once fought with a big whale, and it was dark. As a result, I lost both sides.
But the most incomprehensible thing is, this? King of squid? I don't know why, but often. Hard? Suicide, what is this?
1976 10 In October, thousands of squid suddenly poured in on the vast beach along Cape Cod Bay in the United States. They are like a mighty army of squid, one after another, swimming bravely to the coast, to be precise, crashing into the coast. In a short time, their bodies covered the whole beach. After the local people found out, they tried to help them out of trouble in various ways, but it was a drop in the bucket, because there were too many and the body of the king squid was so huge. Then 1 1 month, the strange thing of squid collective death happened in other places along the Atlantic coast. Sometimes, as many as100000 squid die in one day. This huge disaster lasted for more than two months until1mid-February.
Why do squid die in groups?
With the gradual evolution of human industrial civilization, the ecological environment of the earth has been destroyed unprecedentedly. Therefore, the first thing that ecologists think of is the pollution of the marine environment and the reasons for the change of the ecological environment. Similar incidents can be said to happen everywhere, and it happened in Japan? Crazy cat jumping into the sea? Those cats committed suicide by jumping into the sea collectively because of mercury poisoning. Then, this mysterious collective suicide of squid is probably caused by marine pollution. However, after dissection, it was found that there were no pollutants in their bodies, and these squid did not suffer from any diseases.
While people are still asking questions and conjectures, the same incidents have occurred one after another along the coasts of Britain, Iceland, Denmark, Norway, Japan, New Zealand and other countries. Batch after batch of king squid? Active? He ran to his own death graveyard, ended his life and left a huge body.
Biologists all over the world still dissect the dead king squid, and their limbs are all intact, and there is no injury on their bodies. Is there something wrong with their internal organs? Or other unknown reasons?
In order to solve this mystery, Norwegian zoologist Orr? Blix made a careful study of a dead squid with a length of 10 meter. He found that the blood of this king squid has poor oxygen carrying capacity. This oxygen carrying capacity is affected by water temperature. When the water temperature rises from 10℃ to 15℃, the oxygen carrying capacity of blood will suddenly decrease to 1/4 of the original, which will make various internal organs in the body suddenly lack oxygen and fail to work normally, thus leading to sudden death. The king squid generally lives in the deep waters of the North Atlantic and the North Pacific, where the water temperature is below 10 degrees Celsius. However, the sea environment is ever-changing, and there are thousands of cold currents and warm currents all over the sea, which crisscross and form a very complicated hydrological environment. If the king squid passes through large warm current areas such as the Mexican warm current, the North Atlantic warm current and the Japanese warm current, it is very likely that it will be deprived of oxygen due to the increase of water temperature and finally die.
It seems that the cause of the collective death of the king squid has been found. However, this can't explain why they choose to rush to the doomed coast collectively. After all, survival is the instinct of animals. Why do they ask for death in an emergency? The above explanation seems unable to justify itself. Squid? Mysterious death? The reason is still a mystery.
