In the scientific world was a sensation. To the delight of all the supporters of the protection of nature in the Mekong Delta, located in the territory of Vietnam, biologists lucky enough to spot dolphins iravadiyskih 20 individuals. No one yet knows exactly these rare aquatic mammals are there in the moment. According to the World Wildlife Fund in August 2011, it there were no more than 87 individuals total.
Unlike other aquatic animals of a dolphin, dolphins kind Orcaella brevirostris is long under threat of extinction. Despite the fact that these creatures all over the world, only a couple of hundred, the discovery in the same place as many individuals - just 20 dolphins - was unparalleled success.
Iravadiyskih population of dolphins found during an expedition to the South of Vietnam, in the conservation area of Kien Giang researchers Vietnam Institute of Tropical Biology. "Iravadiyskih dolphins were more than we encountered earlier in the Philippines, the Gulf Malampayya or in any other place in the Mekong", as reported by one of the leaders of the expedition on the Internet portal PC-Games.
It is believed that this aquatic mammal is iravadiyskity dolphin - this being very unusual and interesting. Researchers have long believed that it is the only representative of the entire family of dolphins, which is completely devoid of even the slightest similarity "beak" (the dolphins is called a small ledge on the face, formed by elongated jaws). Among other things, these dolphins - it’s one of the rare cetaceans that can move the neck in different directions.
Despite the fact that, apparently, the contacts of a person with dolphins began when people only began to settle the land of Southeast Asia, scientists know very little about them. Statistics zoologists around the world they are marked as "kind of data-poor." We know that these are friendly, smart and always live animal contact groups consisting of three to six animals.
Another interesting fact, and one that adults are free to move from group to group (for most species of dolphins is not the case, and to strangers in groups, they are very cautious). At the time of the study unfamiliar territory Dolphins lift their heads out of the water and start to rotate to see all that surrounds them. These mammals swim very slowly, and never in breathing do not stick your head out of the water completely. That’s why they are not so easy to see in the wild.
