Dear friends! It's about the fountain, but not quite normal!
Why whale fountain of
Keith - this is not a fish, as many think, but a mammal. Of course, it looks different from the usual cats and dogs to people, but it is also their cubs feeding milk. Whales appeared on our planet as a result of evolution. Their ancestors did not live in the ocean and on land. So the whale as a new form of life on the planet, took to adapt to aquatic habitat conditions. Although whales live in water, they do not have gills. Their body breathing nature created light. During the existence of whales their respiratory system is constantly evolving. Nostrils gradually moved from the end of the head up. At present represented by a pair of whales nostrils breathing holes. They make it easier for oxygen. When the whale submerged in water, it closes the airway to prevent the ingress of water. For this purpose, it has a small valves. Do whale digestive and respiratory systems are not connected with each other. Therefore the ingress of water into the lungs through the mouth excluded. On the surface of the ocean whales pop up every 10 minutes. But if necessary, they may be in the depths of the sea to 45 minutes. When the kit is shown on the surface, the first thing it releases light from used air. Furthermore, this procedure is accompanied by a loud noise that can be heard at a great distance. This is the cause of a strong fountain. Fountain that spews kit consists of exhaust air and water vapor. To dial a lungful of fresh air kit produces fountain repeatedly. Thereafter it is lowered to the deep sea. It is known that some whales can dive to a depth of 600 meters. And some particularly large representatives are able to raise the tail above the water and jump into the air, completely breaking away from the water surface. Source: I-fakt.ru
