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).

Dolphins can emit echolocation signals to investigate the situation and detection of obstacles, and the so-called “whistle”. These signals they tell each other about your condition. For example, “I’m in trouble” is a great melodic whistle, following a short and dull. “I’m angry” – it sounds like barking. There are sounds that indicate a greeting, farewell or disturbing. Those signals dolphins recognize members of his clan. Proven fact was that each Dolphin has its own name, which receives immediately after birth and responds to it all his life.
The most talkative representative of the Dolphin is the Beluga, or white whale. They povizgivayut, whistling at high frequencies, produces a melodic shimmering trills and sounds like a cackle, chirp or mauganui. Belugas can even imitate bell ringing or voices of birds, which have never been seen. These competencies often referred to as “sea Canaries”. Continue reading
The most important thing to remember: do not rush immediately to capture dolphins when you are near them. Dolphins are social creatures, and they are generally well configured to communicate with people. However, in their natural habitat they prefer to communicate with us on their terms.
Your shots will be much more successful if the dolphins will show to you a lively interest. After all, very few people impress pictures of dolphins swim away in panic away.
Photographing dolphins in the open sea keep in mind that the sea waves and the salty mist at any moment can hurt you and your equipment, especially if you are traveling on a small boat. So try to protect yourself and your camera from falling into the water. Continue reading
The brain of a Dolphin is not only a lot of weight, but has a complex structure with a large number of convolutions of the cerebral cortex, the superior part of the brain responsible for complex mental functions. But the highly developed brain is a sign of high intelligence and highly organized, complex behavior. 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
From 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
