As dolphins detect underwater minesSuch as active sonar, unlike passive, not only picks up sounds that are distributed objects, but he sends call letters to them. Industrial fish finders are used during military operations to detect underwater enemy ships and navigation of the peace courts.

Unlike humans, dolphins use echolocation, also called biosonar, for the past several millennia. And needless to say, they are incredibly successful in this! The ability of the supersensitivity built into their DNA, so they can easily be distinguished in the water pneumatic BB gun from a little wheat grain at a distance of 15 metres or more.

And the dolphins have confirmed this fact, because they are skillful hunters, caring parents, disciplined members of the pack, and if necessary – and competent leaders. Continue reading

Combat dolphinsThe military does not get tired to surprise and even shock of civilians with new types of weapons. The turn of the dolphins.

The Experience Of Russia

Oddly enough, the first attempts to train marine mammals for military actions have been taken in Russia, and the proposal made by Vladimir Durov, however, about the seals. Famous animal trainer suggested using animals as the bomb squad. Unfortunately, they all died in the result of sabotage by enemy of Russia – Germany. Case of poisoning combat seals investigated to the end and was not due to the revolution of 1917. Papers that reflect this learning, were eliminated, so they couldn’t use the enemies.

Dolphins love to imitateFrom the point of view of the trainers, imitation is a very useful quality of cetaceans. Because it significantly reduces the time of training dolphins. Furthermore, by imitating the stunts begin to perform even those animals that were not conducted special classes, just that they were near relatives, and observed their tricks.

So, in the Californian small aquarium whale learned the tricks just on the basis of the observation of his companions-the bottlenose has worked with coaches. In another case, Atlantic bottlenose dolphins are placed in one pool with tropical revolving prodelphinidin, adopting their manner of spin-axis during the high jump body into the air. Because the ranges of both species do not coincide, the animals can learn this technique in the wild. Such examples can be cited. Continue reading

Elusive Amazonian dolphinsThat’s why the eyes of rime is different from other cetaceans. If marine dolphins eyesight adapted to catch very faint, rime has some semblance of “sunglasses”: cornea and lens are yellow colour, protecting the eyes from sunlight.

To date, scientists using a special method sippa, found about 180 communication signs in marine mammals. Researchers are working on their systematization, and even try to compile a dictionary of communication of dolphins. However, despite numerous studies, to fully decipher the language of dolphins so far and failed. But the communication between these intelligent animals are poorer from it is not. Continue reading
