Dolphins are favourites not only of children, but also many adults. They are bright and beautiful. Nevertheless, it is wild animals which are senseless for idealizing not only, but also it can be unsafe. Many myths surrounding these sea inhabitants are already dispelled, will be to get acquainted with them to nobody superfluous.
Relation of marine animals to each other
During the period from 1991 to 1993 the scientists Harry Ross and Ben Wilson were engaged in studying dolphin corpses in the territory of a northeast part of the Scottish coast. As a result of this work it was revealed that on bodies of some dead of animals there are serious scratches and distinct traces of stings.
Scientists found out that only relatives of the dead of dolphins could put similar injuries. Theories about the damages put with fishing networks or rowing screws were disproved. From 105 found corpses turned out 42 with the deep injuries left by other individuals.
Friendliness of dolphins
Animals lovely at first sight do not pose deadly threat for the person only owing to the food preferences and rather small sizes. But if other food is not near, large falcated ducks are able to afford human flesh.
People from dolphins can suffer serious injuries. Stories when these individuals bit the person in the course of feeding are known. It is possible that they elementary confused the stretched extremity with a live big fish, but it is only one of versions.
In the sea the people can be also endangered attacks from dolphins. The animals hunting for a fish jamb are capable to apprehend the swimmer in a diving suit as the competitor. As a result they can ruthlessly begin to push away the person from production, creating real threat for his life.
Doubtful advantage of dolphins for the person
There is a set of stories how dolphins became heroes, saving the sinking person, beating off him from sharks. Really, specially trained individuals are capable to help, but from wild representatives of similar you should not wait for Delfina. Out of curiosity can approach sinking, even to allow to touch itself. But having made sure that people are inedible, they departure.
Marine animals can promote acceleration of death of the sinking exhausted person, having begun to play with it. As for protection against representatives of predatory fishes, a shark with dolphins are at odds. Therefore the pack of "smiling" animals which is near the swimmer involuntarily frightens off toothy murderers.
There is a version according to which dolphins are "therapeutic" animals. However by scientists it was not proved that joint swimming with dolphins is capable to help the person to get rid of physical or psychological diseases.
Manifestation of sexual activity
The bisexual relations are peculiar to dolphins as gomo-, and. These animals have rather high sexual activity. And they can be interested not only similar individuals, but also representatives of other animals, objects and even people. The dolphin will not manage to rape the person, but in the course of the sexual game it can involuntarily drown it.
Scientists found out that they in packs of a female quite often are exposed to violence, and can participate in process up to 2-3 males. The victim surrounded with them is exposed to persecution until it is not left by forces. Similar coercion to copulation can last for several days, and at times even weeks. Besides, researchers note that dolphins are capable to make attempts of pairing with anything, even a sewer pipe in the conditions of the pool.
Dolphin smile
The most part of dolphins has such structure of a muzzle at which the lower jaw is pushed forward. It makes an impression as if the animal constantly easy smiles. Though dolphins are also capable to feel grief or joy, but the human mimicry is alien to them. The individuals attacking people will "smile" also lovely, as the animals entertaining the people in a dolphinarium.
Care of the posterity
Sounds terribly, but dolphins are capable to kill own kids. In the 90th on coast of Virginia , corpses of the newborn animals who died from stings of adult relatives were found. Researchers repeatedly noted aggressive behavior in relation to cubs and at observation of dolphin packs in the conditions of the high sea.
Similar murders have the only explanation. After posterity birth at a female interest in an opposite sex vanishes, she completely gives herself to care of the kid. If he perishes, to it the former activity is restored. And men's individuals quite often use it.
Mental capacities at dolphins
Numerous researches could not prove the fact of presence at sea inhabitants of special mental capacities. Really, dolphins are capable to communicate by means of raznochastotny sounds, to remember and recognize each other. They differ in extreme curiosity, not bad give in to training. Nevertheless, scientists cannot call these animals clever. To them it is not allowed to cope with any logical tasks or to draw conclusions. Therefore there is no sense to idealize dolphins as on the level of intellectual development they hardly differ seals or sea lions.
