Interesting facts about the whales

A blue whale cub is called ... a calf. The calf is born after a year of pregnancy, it weighs 2-3 tons and reaches up to 7 meters in length.

Did you know that a whale cub starts swimming immediately after birth. Having been born, he must take a breath, otherwise he will die if he gets into the water with his lungs not filled with air. The female whale at the moment of giving birth raises the body above the water. The cub, falling into the water, manages to breathe air. The expanded lungs impart buoyancy to it.

The young are fed under water, the duration of each feeding is short (a few seconds). Feeding the kitten is not an easy task: the baby has no lips at all. Underwater, he covers one of the mother's two nipples with a rolled-up tongue. He does not have to suck: his mother injects milk directly into his throat. The cub drinks up to 200 liters of thick, creamy milk per day.

Whale milk is thick, like sour cream: the sperm whale has up to 53% fat, and baleen whales have about 37% (good cow's milk has 4% fat). Its surface tension is 30 times greater than that of water, which is especially important considering feeding under water (the milk stream does not spread in the water). The nutritional value of whale milk is very high. After 7 months of life, the "child" weighs up to 25 tons! Blue whales are the fastest growing animals in the world.

Blue whales have long-term vapors; it is known that the male always keeps close to the female and does not leave her under any circumstances. Whales protect their offspring from killer whales and white sharks, especially dangerous for them, by driving young animals inside the flock.

Hugs between mother and baby are expressed by touching their noses.

After six months, the kitten feeds on its own, but does not leave the mother, who helps him. She circles around the accumulation of plankton and drives food to her baby. In general, mom - she and the ocean mom.
