Dolphins themselves are amazing creatures that have a large brain and a fairly high level of social development. Before we start talking about white-faced dolphins, we should note some rather curious facts that will allow us to simply better understand these animals.
Educational program on dolphins
First, it should be said about the origin of dolphins, which were previously land creatures and roamed the land, but they did not particularly like the conditions of existence on land, and they just took it and went under the water. Yes, it happens, animals can change their habitat space so radically, although not immediately. Of course, this required a long evolution and a whole outline of body modifications, which from the land became streamlined and able to move under water.
In the new space, the dolphins are essentially lucky, so far they have practically no natural enemies and have abundant food base. In general, the decision chosen once was fairly true.
By the way, dolphins generally prefer comfort and pleasant conditions. For example, they do their best to avoid pain, as evidenced by experiments. As a rule, the dolphin feels a minimum of pain during the period of its existence.
In conclusion, we must say about the dolphin brain, which has always interested scientists with its size and developed structure. However, dolphins use it in a very special way. They "hear" (in quotation marks) the space of the ocean that surrounds them.
The perception of a dolphin is best compared with some instant insight, which allows you to be aware of everything that happens for miles nearby completely and simultaneously. It is for this that dolphins need such a big brain in order to receive and realize the world as completely as possible.
White Sea Dolphin: Appearance Features
A distinctive feature of the white-mouthed dolphin is the five-centimetric beak, which makes these animals cute and cute in appearance. In color, they have a dark back and sides, but the abdomen has a white color. The teeth are about 7 millimeters long and in number can vary from 22 to 28 pairs. Of course, people of these teeth should not be especially afraid. For the most part, the dolphins are quite peaceful with respect to people in particular, but still some caution should be exercised.
The white-faced dolphin inhabits mainly the waters of the North Atlantic. If we talk about the territory of Russia, then there it is found in the waters of the North Sea and the Baltic Sea, it also floats between the shores of France and Iceland, travels even in the Massachusetts Bay area. It is completely unknown how exactly these dolphins migrate, this issue remains almost completely unexplored.
Lifestyle in natural conditions
White-faced dolphins are not individualists, they are collected in flocks, or rather groups that make up to eight representatives of the species. In such groups can form pairs, which are quite stable, that is, animals are almost monogamous.
As well as some other sea animals, they can gather in huge colonies. This is due to the presence of food in a particular location. If there is a lot of food somewhere, then dolphins can gather up to one and a half thousand in a colony.
They multiply in autumn, somewhere in the transition from summer to autumn. The period of existence is about 40 years. Strangely enough, but in greenhouse conditions of bondage they feel worse, and the period of existence can also be reduced.
They eat, surprisingly, a variety of seafood. These include different varieties of mollusks and crustaceans, different varieties of fish.
Interesting details
Much of these dolphins is still unknown, they are rather mysterious animals, but scientists have managed to figure out some of the details so far.
- White-faced dolphins love to have fun. They periodically jump out of the water and make a revolution in the air, after which they find themselves again in the water. There is no practical benefit from such an action, but there are quite a lot of joy and dolphins, apparently, know how to have fun.
- In addition, these dolphins have underwater games. Floating, they chase the algae, often not quite for food, but just to have some fun.
- On the other hand, they also know how to be sad, and when it becomes especially sad, they are thrown onto the land in order to rest peacefully there, leaving the mortal world.
- The ultrasound that the white-faced dolphins emit is like a flower on the graphic. There is also information about the healing effects of this sound.
They are listed in the Red Book of Russia. At the same time in Russia, these dolphins were never caught for fishing, and in general they were not particularly caught. However, there are countries where white-faced dolphins are eating, for example, in Iceland or Greenland.
In general, at this period they are beyond the threat of destruction and the world population remains fairly stable. The total number of animals is about hundreds of thousands.At the same time on the territory of Russia the white-faced dolphin belongs to endangered species.
To summarize, however, it should be optimistic words, because in order for these animals to maintain their own population, people have little to do. If you do not begin active fishing, they can remain beyond the verge of extinction and continue to inhabit the abundant ocean expanses.
