Almost all living creatures on our planet know how to speak, only they do it not with words. For communication they use different sounds, movements and even the smells that you simply do not understand. To talk among themselves even know how the penguins — how else would they could get together to go hunting and even to organize "kindergartens" for the education of young? Of course, without any sounds and movements to create an entire society they could never do it. But scientists have long been interested in one question — can the penguins make sounds under water? Wouldn't it be great to know that the inhabitants of cold of Antarctica to communicate with each other even while snorkeling, pointing out places where fish and other food.
Interesting fact: in the first two days of the week, the young Chicks are close to one parent while the other goes hunting. When the Chicks get older, give them to the "kindergarten" group for the cubs, who are under the protection of free penguins while their parents are in search of food.
And so the penguins warm their young — that's solidarity!
While on land, penguins communicate with each other using sounds similar to a crackling rattle. But the scientific evidence that they are able to communicate with each other during spearfishing, scientists are still not there. Penguins communicate under water seemed unlikely, because in search of fish and squid they can descend to a depth of from 20 to 500 meters. And at this depth on their bodies is a big load and squeeze out any sound they seemingly could not.
Today, even the biggest penguins almost breathing people in the navel, but once upon a time they were huge. You can read about this in one of the
But scientists from South Africa decided to carry out research and finding out the penguins know how to talk under water or not. The work was carried out on the example of king, macaroni and gentoo penguins. The choice fell on these species because they eat all kinds of food and, consequently, dive to different depths. So the king penguins eat fish and can swim to a depth of 200 meters, and penguins eat small crustaceans at depths to 10 meters. Gentoo penguins as versatile and can float on the surface and dive to great depths.

To Check if penguins communicate underwater, it was pretty easy. Scientists caught the animal and fastened on their backs camcorder with protection from moisture. In General, they were able to record 203 of the video, after viewing which was done four output:the
The authors of the study admitted that the findings were unexpected for them. Although, they would should have known about the possibility of communicating under water. The fact that other groups of scientists have repeatedly proven that underwater communication is capable of sea turtles, seals and dolphins. Therefore, the ability of the penguins is not surprising.

Now, scientists have proven that penguins are able to communicate under water. Cool. But there are several questions that they still can't give accurate answers. For example, it is unknown how the penguins, dolphins and other diving to great depths animals able to produce sounds under a lot of pressure. And anyway, why would they publish them?

The first question to give even a hypothetical answer is impossible. But about the second there are some thoughts. The penguins and similar animals can communicate under water, to notify each other about places where food. Or another option — they make sounds to help each other to navigate in space. After all, under the water, which is similar to boundless space, very easy to get lost.
