Why do whales and dolphins beaching (7 photos) Bashny.Net

There are several theories to explain this phenomenon, but it is only version.

1. Climate change. According to this version, the death of whales explained by changes in ocean currents that bring colder water from the Antarctic. The whales are swimming in shallow water to get warm.



2. pollution of the oceans.
Supporters of this version claim that in the respiratory tract of many whale strandings have been discovered oil and even polietilen.Protivniki this hypothesis argue that many whales suicide was purely respiratory, and water in their places of "suicide" is not contained petroleum products. Radiation in the area of ​​emission whales also noted nebilo. Thus, the version that caused the deaths of whales is pollution, bears little resemblance to the truth.



3. Diseases. Whales are also sometimes get sick. Scientists suggest that cause the release of whales can be parasites that settle in the bodies of animals and damage vital organs. Perhaps the reason lies in the mental illness of the leader - the leader of "gone mad", and the whole pack rushed after him.



4. Mutual aid.
Whales have always come to the rescue neighbor from his pack. If one of the whales mistakenly wandered into the shallow water, it immediately begins to give signals relatives and those rush to the rescue. Alas, whales, instead spastitovarischa themselves get into trouble.



5. In close quarters so mad.
Japanese scientists have proposed a version: when the number of whales becoming too numerous whales self-destruct. Due to this self-regulation, the number of whales remains within specified nature. However, many environmentalists have strongly opposed this version, considering that the popularization of this hypothesis may lead to the resolution of the resumption of whaling.



6. Broken compass.
Whales perfectly oriented in the ocean, so biologists say that in mind they have a magnetic compass, making these sea creatures mogutorientirovatsya in the magnetic field of the Earth. If there is a whale in front of the geomagnetic obstacle, their inner compass goes down, and they start to go the wrong way. It is known that the rescued whales often beaching themselves again. Perhaps it just explains the breakdown of the compass - the whales back into the water, but can not navigate.



7. Noise.
This theory is currently the most popular. Scientists claim that whales and dolphins ruining deafening roar of submarines. Losing hearing, whales are no longer navigate and beaching. Investigation bodies vybrosivshihsyazhivotnyh gave reason to believe that the cause of suicide is caisson disease (decompression sickness). There is a malaise that is when there is a sharp decrease in external davleniya.Kessonnuyu disease called disease divers, pilots and workers, workers in caissons (underwater working chambers).



Unfortunately, the self-destruction of whales remains a mystery. Odnakouchenye continue to conduct research and maybe soon they will find the answer to this question for many agonizing.
