The whale species list, photos. Toothed whales: a types of

Whales – some of the most amazing mammals living in the water spaces of the planet. These animals m the largest of all today known to mankind. Moreover, the ocean is still not fully explored, that is why scientists periodically introduce new species of toothed whales, generally small, but still. Whaling today has led to the fact that the whale species is constantly decreasing, as well as their population, which is very sad.

Classification

All whales are divided into two large groups, the so-called suborders. Although it is worth noting that scientists identify three subspecies. One of them – the ancient whales. All members of this group have long been extinct, and to describe them makes no sense. We will talk about the animals that swim in the oceans and seas, though there is a threat of their disappearance.

One of these suborders-baleen whales. In addition, they are often called “real whales”. The second suborder-toothed whales. Smaller representatives, which include dolphins and porpoises, but more on that later. I would like to mention that different species of whales are subject to destruction. In particular, this applies to those who have the greatest value in hunting. Is the blue whale, fin, humpback, etc.

Types of whales: a list, a short description

We Begin with baleen whale as the largest and most ancient. This includes a variety of species of whales that are worthy of your attention. It is easy to guess that to find such an animal can cause in the mouth. By the way, the whale is also appreciated, therefore, these animals often become the prey of poachers. The largest member of the suborder – the blue whale. The highest recorded species reaches a length of about 30 meters and a weight of 150 tons. And it is absolutely peaceful animals, whose diet for the most part is plankton and mollusks.

The bowhead whale is an outstanding representative of baleen whales. The length of this giant sometimes reaches 20 meters, the trunk of the animal is black, without stripes. It is noteworthy that the head is approximately 30% of the total length of the whale. It lives exclusively in the Arctic seas. Today it is practically extinct, which is extremely rare. The reason for this was commercial whaling.

Dwarf and baleen whales

South smooth kit is similar to the harp like in appearance and size. Therefore, an inexperienced person may confuse. Although it is easy to guess that the habitat of the animals is very different. Southern baleen whales are not found in the Arctic seas, as Greenland is not seen in the temperate zone of the Pacific and Atlantic oceans. From about the 10th century of our era whaling on baleen whales is only expanding. Today these animals are under full protection, according to the latest data trends in the breeding kind positive.

All species of whales, a list of which you can see in this article are amazing and unique. Take, for example, a dwarf whale. It is so named because of the small size. Usually individuals do not grow in length more than 6 meters. But if you do not take this parameter into account, then the rest of the animal is no different from their relatives.

Endangered whales

A Family of gray whales one of the most exterminating now. It is quite large with a length of 15 meters, do not have dorsal fin. In the 18th century the population numbered about 30 thousand individuals. As a result of active whaling, the number of gray whales by 1947 was reduced to 250 individuals. Then a family of gray whales were taken under constant protection of these animals today, there are about 6 thousand.

Not to mention the family plastikovyh. These include humpback whales and these whales. As those and other – endangered species of whales. If still in 30-e years of our century in the Antarctic, there were about 250 thousand fin whales, but today this figure is five times less. Of the 100,000 blue whales that once lived in Antarctica in 30 years, 1962-th survived only 1 000-3 000 individuals. Approximately the same situation with SEI and humpback whales, which are under constant guard. Largest striped whale – blue. He also – the only whale species that leads a nomadic life.

Toothed whales: types and description

The Suborder of toothed whales has a large number of families. What unites them is the presence of teeth, although the size and their number may differ materially. Almost all representatives have a small body size. The only exception is the sperm whale. Of course, oceanic dolphins and harbour porpoises are the most well known of the suborder of toothed whales. The majority of these small animals.

The easiest appearance to define the white whale. This can be done by the color of his skin. The size of Beluga whales is a small, usually up to 5 meters. They are found almost everywhere. Sometimes, these whales swim to where to live. It is impossible not to allocate the only representative of the genus narwhals-the narwhal. They are somewhat similar to white whales. However, narwhals have 2-2,5-meter long tusks on the head that is unique to males. In this caselength of the animal is about 5 meters.

Porpoises and dolphins

Here we come to the subfamily of the Dolphin. Not to mention that it includes a large number of species and even more subspecies. Only about half of the whales known today. For example, the common brown or simply Dolphin porpoise in length usually not more than 2 metres. The back of the animal is black, and the belly is almost white. Dolphins mostly prefer warm waters and temperate latitudes. Often swim far up rivers. It is interesting that a race of porpoises living in the Black sea.

The Following types of porpoises live in different parts of the seas and okeanov:

• Californica;

• Ochkova;

• Chernaya;

• Black bespechna etc.

The appearance of all types differs insignificantly, as well as the size. In General, however, even though animals of prey, but very peaceful. Studies have shown that some species of whales and dolphins have a highly developed brain. What makes dolphins are truly amazing, as is their ability to communicate – echolocation. This kind of language, most of which sounds strange for a person today.

A Genus of sperm whales

As mentioned a few above, sperm whales – the real giants among all toothed whales. At length the animal can reach about 20 meters. It is a gregarious whale, which can be found in all the oceans of planet Earth. The exceptions are females and young whales, who prefer to stay in warm waters. Today it is not fully investigated. In particular, it is unknown whether males return from their distant migrations. Scientists still have not figured out why they swim so far, although the most likely theory is that they are looking for food. In commercial terms, the sperm whale is very valuable. This was particularly noticeable in the years after the second world war. Near the coast of Chile and Peru, these animals, particularly females, was virtually destroyed, which seriously threatened the population. Even today in all the oceans of the world are being hunted and exterminated toothed whales. Species with particular value to humans are not.

Conclusion

Here we discussed the main types of whales. The names of these animals were assigned more than one nation of the world and not only in the 21st century. Unfortunately, even today there is an active fishery. How many kinds of whales left today? About 40, and despite the fact that there were more than a hundred. It's one thing when the process is monitored, and quite another when there is uncontrolled catching and destruction.

Of Course, you can endlessly talk about what from the brain of a whale produce insulin and other hormones, and liver-vitamin A. in Addition, meat used for making expensive sausages. But all of this can be found in nature, not destroying different species of whales and not reducing their population. Well, that's all there is to tell about the whales and the diversity of their types. Most are quiet animals who rarely attack humans.
