Interesting facts about penguins
Fact 1. There are 18 species of penguins in the world, and there are both similarities and differences between them. The largest of them, the imperial ones, grow up to 110-120 cm, and the smallest, small - only up to 30-33. All of them spend a significant part of their lives in the water, with the only exception here being the magnificent penguin living in New Zealand, which rarely leaves the land. In addition, this is the only species whose representatives do not stray into large colonies, but live apart.
Fact 2. The legs of penguins really do not freeze, because the skin on them is very thick, and there are very few nerve endings in it. These birds, standing on the ice, almost do not feel the cold, and in the icy water of the Southern Ocean they are protected by a thick layer of fat and feathers that are very tight to the body, it is generally impossible to get them wet. Penguins living in Antarctica are able to survive at temperatures down to -60 ° C! Although in such conditions they have to be inventive. To warm themselves, on land they gather in a large crowd, in the center of which it is always warm. Warmed individuals move from the center of the penguin cluster to the edge, making room for frozen relatives.
Fact 3. The worst enemies of penguins are killer whales, which often prey on them. And since these marine predators are not visible under water, groups of penguins often stand for a long time on the edge of the ice floe, not daring to jump into the water. The denouement comes when one brave bird nevertheless dares to do this, and if it does not die, all the rest follow its example.
Fact 4. On land, penguins do not feel very confident. Clumsy and slow, they waddle, avoiding the snow, into which they easily fall. However, they know how to move through the snow, lying on it with their stomachs and pushing off with their wings, like oars. And in the water, the penguins are completely transformed, and there is no trace of their clumsiness.
Fact 5. These birds feed mainly on fish, and, hunting for it, they can dive 150-200 meters under water. Moreover, in the water they move very quickly and deftly, developing a decent speed. The fastest swimmer is considered to be the gentoo penguin, capable of swimming at speeds up to 35 km / h. This is comparable to the flight speed of the tit, which is widespread in Russia. The diving record belongs to emperor penguins, who can hold their breath for 15-18 minutes and dive 500-530 meters under water.
Fact 6. Emperor penguins, the largest of all, are always monogamous - they form pairs once and for life, although in the event of the death of a partner they can find another. They rarely hunt, eating in reserve, on average once a week or two. After that, they digest the absorbed food for a long time, and by the time of the next hunt they become very thin, losing up to 30% of their mass.
Fact 7. The color of the plumage of different types of penguins varies, but they also have a common feature - all of them always have a black back. Black reflects sunlight the worst, thus absorbing the maximum amount of heat. And there is not much heat in such cold and harsh conditions.
Fact 8. These amazing creatures are able to drink salty sea water, and they do not need freshwater sources. Even in the process of hunting, penguins willy-nilly drink salt water, but special glands filter it out, and excess salt is removed through organs like the lacrimal glands located above their eyes.
Fact 9. From time to time, all penguins are forced to go on a long diet. In the process of molting, they cannot swim, and, accordingly, look for food for themselves. The molt lasts from 1 to 3.5 months, depending on the species, and all this time the birds are starving. During this time, they often lose up to half their body weight.
Fact 10. These waterfowl are able to climb even a steep bank. Observations of them proved that penguins can literally jump out of the water with a powerful jerk to a height of up to 1.8 meters! This gives them the opportunity to literally jump onto the shores and icebergs with steep sheer walls.
