Suicide - a voluntary deprivation of life itself. The reasons for such action in humans can become mental illness, the loss of meaning in life, pursuing failure and humiliation of others, the loss of a loved one.
These reactions are inherent in man, but I wonder whether there have been cases of suicide in the animal world?
Quite a common myth that lemmingsJust a few years get in packs to follow for the leader to breakage or water hazard, where they were waiting for a voluntary death. These actions allegedly aimed at to reduce the extremely increased population size and to save species from extinction. But in fact, these small animals prefer to live alone, do not have a leader and a good swim. Recent observations of the scientists showed that a sharp decline in the number of lemmings is not due to animal suicide. In crowded conditions, males are more aggressive and are taken to kill the young, thereby adjusting the number of individuals.
The sad spectacle - some hugemajestic creatures lie on the ground, dying under the weight of his own body. The whales are beaching themselves in many parts of the world, individually or in groups.

"Suspects" are noise that emit submarine faults in the magnetic compass, the animals as well as the disease. These factors can cause disorientation of animals as a result of which they are on land.

Grasshopper, leaped into the pond and drowned there,or an ant, berry pretending to be pecked by birds - is not a suicide, and, in the case of the same ant coined with a fair share of imagination. However, the insects behave in this way voluntarily. They are forced to parasites that occupied their body. In the case of a grasshopper culprit is the hair-worm larva. Adult worms need water, where it can multiply, so it causes the host to take him there. A nematode living in a youthful American ants, you must enter the body of birds, to complete the cycle. Therefore, they make part of the rear of the owners of red, berry-like, and make them sit stolidly on the branches, instead of trying to run away when danger appears.
Often the parasites not only change the behavior of its owner, pushing him to death, but also to make the death to protect their offspring.
Not all cases of animal deaths, remindingsuicide, scientists were able to successfully explain. For example, in Scotland, there is a bridge called Overtown, from which the dogs jump on a regular basis. The majority of falls from height pyatnadtsatimetrovoy end with the death of a dog, but some persistent suicidal done it twice.
