The blue whale is currently the largest animal on the earth. An adult blue whale can grow to more than twice the weight of the largest dinosaur that ever lived on the earth, the Gibosaurus, and 30 times the weight of the African bull elephant. About times. Blue whales are real sea monsters, with an average length of about 26 meters, a maximum record of 33.5 meters, and an average weight of 150 tons. Such a giant beast needs a lot of food. An adult blue whale consumes about 1 million calories a day, which is equivalent to 1 ton of krill. Krill is its bulk food. Blue whales swim into the shallows and swallow mouthfuls of water and krill. The krill are filtered out by the tongue, which acts as a piston and forces the water out through the large sieve-like structure of baleen that hangs on either side of the upper jaw. A blue whale's tongue is more than 3 meters thick and weighs more than an elephant.

Blue whales are mammals that breathe with lungs, so they need to come out of the water to breathe every 10-15 minutes. When a blue whale emerges from the water, it expels carbon dioxide from its lungs through its nostrils before inhaling. The hot and powerful carbon dioxide exhaust gas discharged from the nostrils was accompanied by a loud scream, and the nearby seawater was swept out of the water to a height of about 10 meters, so a spectacular white fog column appeared on the sea.

Blue whales once roamed all the world's oceans. According to statistics, there were 250,000 of these giant beasts in the Southern Ocean alone. But in recent years, ruthless whaling has reduced the number of blue whales to less than 1% of the total. Determining the number of blue whales is difficult, but current estimates range from a few hundred to 11,000 in the Antarctic. Whether this number is correct or not, it is dangerously low compared to what it once was. Although whaling has been restricted for the past 50 years, with a ban imposed in 1967, commercial hunting of blue whales continues under the guise of scientific research.

Blue whales migrate great distances, and in the summer they live in polar waters, feeding on large amounts of krill near the edges of ice floes. , especially addicted to eating krill. When the blue whale eats, it opens its huge mouth to let seawater and zooplankton pour in, like a confluence of rivers. Then it closes its mouth, and the seawater is discharged from the slits in its baleen, and the filtered small animals can be swallowed. Enter the belly. When winter comes, they migrate to warm equatorial waters, traveling thousands of kilometers. It is reported that a blue whale travels more than 3,000 kilometers in only 47 days. Such a long journey takes them far away from their feeding base, and they do not eat for up to 4 months. Live off your savings.

Blue whales that are old enough to swim the world's oceans alone or in pairs can live up to 120 years old. Despite their solitary lifestyle, they have advanced methods for ultra-long-distance communication and can produce a low-frequency, high-intensity sound. The recorded sound frequency reaches 180 decibels, which is the largest known noise produced by motion, exceeding the noise produced by a jet aircraft in flight. The sound lasts for 30 seconds and can be heard by other blue whales up to 1,610 kilometers away.

The blue whale is also a unique strongman in the animal world. A blue whale moving at a speed of 28 kilometers per hour can generate 1,250 kilowatts of power, which is equivalent to the pulling force of a medium-sized locomotive. A blue whale once towed a 27-meter-long whaling speedboat for 8 and a half hours at an average speed of 9 kilometers per hour. At that time, the speedboat was going backwards at full power, but it was still being pulled forward by it. Traveled 74 kilometers.
