Biography about Kit
In size, this is a mammal, probably, even a record holder of all time. Modern blue whales are even larger than their prehistoric ancestors who lived ten and a half million years ago. The body length of these cetaceans can reach 33 meters, and weight reaches tons of males and - females. We talk about the largest mammal of our planet - and show his photo. The diver swims near the Blue Whale, the Indian Ocean, a year.

As mammals living in the ocean, where much colder than on land, they should be large enough so as not to lose too much warmth. At the same time, whales are limited in size to their metabolism, which accelerates as it grows. Sino Keith, Indian Ocean, year. Photo: Reuters eat blue whales almost exclusively by krille - small crustaceans.
In the summer months, they can eat up to 40 million such crustaceans. This is possible thanks to migration to the Arctic regions, where at that time the sun shines almost 24 hours a day, which leads to a Cricop boom. In blue whales, instead of teeth on the upper jaw, special overlapping plates grow - the so -called whale mustache. Animals swallow large volumes of water, and then filter it through the mustache, holding the krill in the mouth.
Researchers found that blue whales feed during the day, and at night rest at the surface of the water. This makes them vulnerable to ships in the dark, now scientists are trying to collect more information about animal behavior for the most effective work to protect them. Researchers examine the body of a dead blue whale, who died as a result of a clash with a ship, the USA, and a year.

Now blue whales are a protected look, but their number is restored slowly. Now in the oceans there are only 15 thousand blue whales. A large group of fishermen at the murdered blue whale, Antarctic, year.
In the summer months, they eat a lot to stock up on fat during migration. For the second half of the year, whales are busy with mating and the birth of offspring, the period of pregnancy reaches just months in tropical or moderate waters, which are excellent places for feeding young animals - there are few predators, but there is no krill. The cubs feed on the mother’s milk when they migrate back to the poles.
Sin Kit near the Caribbean, Atlantic Ocean, year. Since blue whales are single, it is useful for them to publish low -frequency, high -intensity sounds that help individuals find each other for many miles. Both males and females sing, but the latter - only single notes, and the former can create complex melodies.
True, here it was not without exposure to a person - studies show that in the modern ocean, clogged by the noise of ship screws, whales can hear each other only at a distance of about 15 kilometers.
