Why do whales die when they are stranded? Why do whales run aground?

There are different opinions on the reasons why whales are stranded or even commit suicide, but most of them are related to their echolocation system. What's the matter with whale stranding and even killing themselves?

Other scientists found that most of the dead whales suffered from redness and swelling on both sides of the air cavity after several whales rushed into the beach to commit suicide. Therefore, they thought that the reason for the stranding of whales may be that the localization system of whales suffered from pathological changes, which made them lose the ability of orientation and localization. Since whales are gregarious animals, if one of them rushes into the beach and runs aground, the rest will desperately follow up, so that they run aground one after another, forming a tragedy of collective suicide.

First: whales are large mammals living in the sea. Like humans, they breathe with their lungs. But it is strange that it can't leave the sea at a single step. Unlike seal and seal, though they live in the water, they often go ashore, especially in the breeding period, and they gather on the land in groups. The whale can't go ashore because of its bulky size. Its ribs and sternum are very fragile, the chest wall is very soft, and the abdominal cavity has no bone support. So when it lives in the water, it will not be uncomfortable or inconvenient because of the buoyancy of the water. However, once it is placed on the land, due to the huge weight of the body, the fragile bones can not support the heavy pressure, and the chest and abdominal cavity, lungs and heart and other internal organs will be severely compressed, resulting in great difficulties and obstacles in breathing and blood circulation. Therefore, if a poor whale is caught ashore, it will suffocate and die in a short time.

Second: because the whale's body needs a certain amount of salt and water to maintain the balance of physiological functions. Once it leaves the water surface, all parts of the body, especially the skin, will lose their moisture and die of thirst.

Third: because there is no water to cool down, the temperature of whales will rise, leading to death.

Fourth: long time grounding, lack of food for whales, resulting in hunger; plus skin cracking after exposure to the sun, resulting in inflammation. So whales are easy to die when stranded.

Fifth: whales are not able to breathe to sustain life, nor are they dying of dry skin. In fact, the main reason why whales are stranded is that the military ultra-high frequency sonar detection instrument has caused devastating damage to the magnetic induction area of all whales in a certain sea area, which is the brain tissue of whales. So whales will rush to the beach and run aground, so many autopsies haven't found anything special, in fact, they died of functional necrosis of the brain. In fact, there are environmentalists waiting at every place where whales are more often stranded. Once they are found stranded, they will experience their return to the sea, but unfortunately, this method has not been successful, because sending them back to Then they ran aground again because their brain had been damaged
