What kind of animal is that

A whale is a mammal, but a mammal is unique, unlike the rest. Scientists have proven that their ancestors long ago led a terrestrial lifestyle. By the way, they had a wool, a tail, and also paws. Today it is hard to believe in it, but the fact remains. The newest studies have proved that the closest relative of the blue whale (and any other whale in general) are artiodactyls.

The blue whale has incredible dimensions. In them he surpasses all in the world. Yes, it really is the biggest whale in the world. There is no other living being more than him. The blue whale in length is thirty-three meters (maximum). Its weight can be equal to one hundred and fifty tons.

The body of the blue whale is elongated. All of it is covered with a smooth skin, which is very even. There is practically no wool. Color - gray-blue. There are dark spots.

The fountain, which creates a blue whale, releasing air, can reach ten meters in height. Due to their large size, blue whales are not kept in aquariums.

By themselves, these whales live in the oceans. The cold waters of the Southern Hemisphere are the homeland of the largest specimens. Note that the warmer the water, the smaller the size of the blue whales that live in it. The waters of Sri Lanka are one of the most suitable places for watching blue whales. Annually thousands of tourists come to these areas only to look at the largest animals of the globe.

In summer the blue whale lives in cold waters, but closer to winter it moves to where it's warmer. He does this in order to save the lives of his young, the subcutaneous layer of which has not yet formed and has not become able to protect them from the severe cold.

He traces it with the help of special antennae, which are located on the upper jaw in the usual place of the teeth. Sexual maturity will come in fifteen years. A blue whale can survive until the ninety years of age.

These animals are monogamous. The male takes a direct part in caring for the baby and protects it from dangers in all possible ways.
