The whales and dolphins know the feeling of sorrow

A group of biologists under the leadership of Melissa Regent from the University of Milan Biocca found that dolphins and larger whales mourn their dead relatives and friends. Anyway, this is what scientists tend to explain the fact that these animals do not leave immediately the corpse of a fellow, even if the fact that he’s dead, is obvious.

Previously, various scientists have found that not only people are able to feel sorrow — the feeling was not alien to giraffes, elephants, chimpanzees and many other living beings. At the same time, quite a long known that dolphins are very intelligent and able to experience quite complex emotions. However, to prove that the feelings of underwater mammals can be stronger than death, the scientists, according to them, decided to prove for the first time.

In their research, biologists have gathered information about the behavior of representatives of seven species of cetaceans, from vast sperm whales to the relatively small spinner dolphins. As it turned out, all these animals living in different parts of the world, in certain situations showed signs of sorrow, which experts have identified as a combination of emotional distress, unusual behavior. Specialists have learned about many instances when cetaceans have moved the bodies of their dead compatriots for a long distance.

In particular, the researchers came across information about the case, previously described by another team of biologists in the Red sea, they saw the bottlenose dolphins (dolphins) pushed ahead through the water a different, smaller individual — maybe your baby — who’s been dead for quite some time, as evidenced by the signs of decomposition. After scientists have tied the corpse of a Dolphin and he went ashore with him, to bury an adult followed them, sometimes touching the body, until the water became too shallow to continue the pursuit, and after this long time remained close to the shore. Another group of experts watched the whale for many days kept in the mouth for the body of his dead baby, trying to keep it on the surface of the water.

According to biologists, their work represents a new argument in the scientific debate whether to equate to certain features of animal behavior to human emotions.

The results of their study, the scientists presented in the pages of science for the Journal of Mammalogy.
