Fountain whale

Kit - this is not a fish, as many think, but a mammal. Of course, appearance is different from the usual cats and dogs to people, but it is also their cubs feeding milk. Whales are warm-blooded animals. The development of the fetus in the womb occurs. And small whales are born not in the form of eggs and live birth. The first days of life of a small little whale his only power is the mother's milk. The whales appeared on our planet as a result of evolution. Their ancestors did not live in the ocean and on land. Therefore, the whale, as a new form of life on the planet, took to adapt to water conditions obitaniya.

Despite the fact that whales live in water, they do not have gills. Their body breathing nature has created light. During the entire existence of whales respiratory system is constantly evolving. Nostrils gradually moved upwards since the end of the head. At present whales presented a pair of nostrils breathing holes. They make it easier for oxygen. When the kit is immersed in water, then the patient's airway is closed to prevent the ingress of water. For this purpose, it has a small valves. In the whale's digestive and respiratory systems are not connected to 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 there is a need, they may be in water depths of up to 45 minutes. When the kit is shown on the surface, the first thing he frees the used air from the lungs. Furthermore, this procedure is accompanied by a loud noise that can be heard on the big rasstoyanii.

This is the reason for the emergence of a strong fountain. The fountain that spews kit consists of exhaust air and water vapor. In order to gain lungful of fresh air, the whale releases Fountain repeatedly. Thereafter, it is lowered into the sea depths. It is known that some whales can dive to a depth of 600 meters. And some very large representatives are able to raise the tail above the water and jump in the air, completely breaking away from the water surface.
