The blue whale is a marine cetacean that lives in the waters of the world's oceans. These whales are of particular interest because they are the largest mammal species on the planet. How can we distinguish between blue (or blue) whales? First of all, it looks really huge, but has a rather elongated and slender body, and the eyes of the animal seem to be small black beads in comparison with it. On the back of the whale there is a special hole - a breath, it helps him to breathe, throwing into the air water fountain. Along the head you can see a crest called a breakwater, which helps the whale to cut through the water and swim faster. There is a small fin in the back of the back where you can see scratches. These scratches are like a human fingerprint, and scientists can tell the difference between whales and each other. The huge tail of the whale helps him to control his giant body with skill, and skin folds along the entire length of his throat and abdomen.
The size of the whale is really striking, because it is the largest animal on Earth. They can be more than 30 meters long and more than 150 tons in weight. These mammals are very well deaf, so they can communicate with each other with special sounds from a distance of several kilometers. The heart of a whale weighs a ton and only makes 5-10 beats per minute. The color of the blue whale is more like gray whale with a dark tide, it got its name because it looks absolutely blue under the water column. Whales can live up to 90 years.
Blue whales prefer to live alone, only occasionally joining together in groups. Whales eat small crustaceans and plankton, which he swallows along with a huge amount of water. The whale spits out water, but the small creatures stay in their mouths and are swallowed later. Because of their size in their natural habitat, adult whales have no enemies, but cubs are often attacked by a flock of orcas, especially at depths where they become weaker due to lack of oxygen.
The blue sea animal, which is known as the whale, has many features and species of its own. It is the largest animal in the world in the 21st century and is also the largest cetacean group.
The whale itself has a large longitudinal body, the upper and middle parts are colored blue, and the whale's abdomen is white. The whale's head is 25% of the entire body, and the nose of the whale is at the top of the head and consists of two nostrils. As such, these nostrils are the ones that produce the flow of water, the famous whale fountain. Closer to the corner of the whale's mouth are its small eyes. In the mouth of the whale is a whale mustache, through which the whale sifts out food. The very size of the blue whale is the record-breaking size of all other animals that have ever existed on Earth. The whale's body length can reach up to 30 meters and its weight is about 150 tons. A whale can gain about 3000 litres of air into its lungs, but the more weight the whale weighs, the greater the volume of its lungs. The whale's heart weight is about one ton, but it beats about 10 beats per minute, which is one of the slowest heartbeats in animals. The whale's skin has a fat layer of about 25 centimetres, although the whale has a lot of fat. Females differ in size from males in that they are slightly smaller.
Despite all the sizes of the whale, it has very poor eyesight and sense of smell, although under water these feelings are not really needed. However, the whale has a well-developed hearing and sense of touch, and can hear the ship's engine at a distance of up to four kilometers. The whale's outer color is blue. Other whale species come in different colors, ranging from classic blue to normal gray. The whale has vocal cords with which it produces its signature sound, which resembles a low ringing horn. The life span of the blue whale is about 90 years, but the oldest whale has been recorded and has lived for 110 years. The whale feeds on a variety of planktons that swim in oceanic waters. Blue whales do not eat ordinary medium sized fish. The feeding process takes place by drawing water with plankton and sifting plankton through the whale's whale mustache and then swallowing the plankton.
The whale's habitats are diverse. The northern subspecies of the blue whale usually lives in cold oceanic waters, while other subspecies are found in different oceanic waters at different temperatures. In summer, the whales live in cooler waters and migrate to warmer waters for wintering.
This marine animal breeds very slowly, usually with one calf whale, and two calves may be born with a 1% chance. In the 21st century, the number of whales decreased significantly compared to the previous years. This was due to the use of resources produced by the whale in various crafts. According to modern estimates, there are about 5000 blue whales in the world today.
