Which mammal is the largest
Interesting is the fact that the mostLarge mammals on the planet Earth are animals are not sushi, and the sea. The record among mammals is a blue whale, the size of which is amazing.
Blue (or blue) whale beats all records andBecomes the largest mammal of our time. The maximum recorded length of this animal is 33.5 m. Only 2,400 people can beat the average weight of a whale (150 tons). But despite such large sizes, these mammals are not predators, they feed on plankton. The heart of the whale, weighing 600 kg, can be compared with a small car, and the language (2.7 tons) - with an African elephant.
Previously, blue whales inhabited all the oceans of the Earth, only up to 250,000 lived in the Antarctic. But now there are not more than 11,000 individuals left, although they live longer than 120 years.
In summer, these mammals prefer to live onnorth, in the polar waters, but by winter they go on a "journey" to the south. Their speed is very high, for example, one whale for a month and a half can swim more than 3000 km. During this period, animals sometimes do not eat at all, but expend the accumulated.
Although blue whales and singles, they havea kind of way of communication with the help of "singing". This sound reaches 188 dB and can be compared with the volume of the jet engine. Cries can be heard by other people of this species, even if they are separated by more than 1600 km. Moreover, these animals can "take" such frequencies that a person is not able to hear.
Biologists are still interested in the blue whale, trying to solve the riddle of their singing and keep these animals, because they are on the brink of extinction.
