Why does the whale commit suicide?

The  whale phenomenon is a strange phenomenon that occurs when the whale  lays itself down on the beach, away from the water, which is the right  habitat for its survival, so the whale dies because of its drought, its  body collapses due to its heavy weight, Which happens in the sea leads to cover his breathing slots.

People  find that there are more than 2000 animals and more, who commit suicide  to death on the beaches. But despite this large number, they are almost  the greatest threat to sea animals except the whale. Ten species of  whales are found to be the ones who commit mass suicide, It was also found that there were ten additional species, rare to do  such a collective act, and found that most of these whales are suicidal  whales with teeth.
Most  whales that live in groups have large links and live in deeper places,  such as amber whales, deciduous whales, flying whales, killer whales,  and ocean dolphins. Whales are known to migrate from place to place, There  may be many species, sometimes only one species, and the bodies of dead  whales floating on the surface of the water. Winds may carry them to  the coast by wind, and whales die in large numbers. Many of them are  displaced, most of them are exposed to wounds and diseases.Where most of these bodies were rotting on the surface
Most  scientists believe that whaling, as well as some fish, may be caused by  severe toxins in the sea, especially the chemical, biological toxins,  and that the cause of suicide is whales. In the knowledge of the identification of directions, and may happen  to be the leader among them is the patient, and during their annual  migration, the course of the journey incorrectly, followed by the rest,  and death is their ally
Some  scientists have also confirmed that some environmental phenomena such  as global warming may lead to a loss of sense of whales in directions,  and possibly the effect of short and medium sonar waves from ships that  deminers in the sea may confuse these whales and divert them from  trends. Scientists  have learned that because of the large whales in the sense of  terrestrial magnetism, they may commit suicide as a result of their loss  and inability to sense them. In New Zealand, huge numbers of whales and  dolphins have been reported to have migrated to the shore, Thousands.
