Still scientific society believed that the whistles were the main sounds made by these mammals, and did not even know about the importance of using pulse-explosive sounds. Scientists of the Research Institute of Dolphins (Bottlenose Dolphin Research Institute BDRI), based on studies conducted in the waters of Sardinia (Italy), showed that these sounds are vital to public life, and vividly reflect their behavior.
“Pulse-blasting sounds are used in the life of a bottlenose to socialize and maintain their position in the social hierarchy to warn them from physical conflict, and this is also a significant energy savings,” said one of the leading researchers BDRI. The analysis, published by the publishing house Nova Science Publishers, in the book about dolphins: anatomy, behavior and risk, represents the most complete set of these pulse-explosive sounds and whistles collected through the use of bio acoustics since 2005 in the waters of Sardinia (Italy).

Adult dolphins reach a length of 1.5 to 3 meters and can weigh from 200 to 400 kg. and more Dolphins that live in cold waters (e.g., near Scotland), usually larger than those that live in warm seas and oceans. Adult males usually larger than females.
Bottlenose dolphins are grey color: dark top and light (almost white) on the bottom. Bottlenose dolphins typically swim at a speed of 10 to 12 km per hour, but may run up to 30-50 km per hour. For breathing dolphins rise to the surface of the water. As they breathe, on average, every 5-8 minutes. Continue reading
Australian biologists a few years ago was watching bottlenose dolphins living in shark Bay and revealed very ugly facts: it turns out that the males of these dolphins in groups of three, to make them handier to drive females for mating. This friendship can last for years
The dramatic events begin to develop when a dispute over a female face two such triples – then each group begins calling his comrades to his side. In disassembly are drawn dozens of animals, sometimes they have a brutal mass slaughter. Scientists have dubbed these bunch of animals “Dolphin mafia”.
But as it comes to females, bottlenose dolphins behave peacefully and even friendly. Continue reading
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.
Then the idea of using marine animals caught the Americans that put together with other mammals and even dolphins. Initially, they served as a patrol, then became engaged in mining, simultaneously neutralizing floating people. Continue reading
