Penguins and unknown things

If any reader has seen director George Miller's Happy Feet movie about a penguin named Mumble who can't sing, but in return, he is very good at dancing, so he can't forget the cute figure. this animal. A bird with a funny body live mainly in the Southern Hemisphere with the lowest annual average temperature on earth. Let's explore the information about the chubby penguins but contain many interesting things.

Scientists still have a lot of questions about the evolutionary history of penguins. Until now, only fossils that existed in New Zealand about 62 million years ago indicate that Waimaru is the oldest penguin species. Their body structure is quite similar to the current penguin, their wings are very short and cannot fly. Only one thing Waimaru did not really live in the water environment and adapt to deep diving to catch prey.

The shape you often see in penguins is the white part of the abdomen and the dark part covers the back. They use short wings to make flippers when diving in the water. The forelegs are used to move on the ground with a rather wobbly look and especially penguins take advantage of the front belly to crawl on the snow whenever they want to go faster.

Types of penguins

There are about 18 different species of penguins in the world. However, among them 13 species have been reduced due to climate, habitat and lack of responsibility in the conservation of human animals. More alarmingly, five species listed as endangered by the International Union for Conservation of International Nature include White-flippered, Erect-crested, Galapagos, Humboldt and Yellow eyed.

Penguins live according to populations

Penguins are population populations, highly social, always concentrated in herds. Each population can reach tens of thousands of children. Although in large numbers and difficult to control like this, each pair of penguin parents, they can identify and watch over their children through special hearing.

Life of penguins

Depending on the different penguin species, the life of this bird is about 15-20 years. In it, they spend up to 75% of their lives living in the sea environment. For penguins, their lacrimal glands are quite special, which can filter excess salt from the blood. Salt is excreted in liquid form through the nasal cavity. So they can drink seawater and live in this environment easily.

Male birds will hatch eggs

Male penguins will assume the role of incubation for about two months while the females will go to feed on the sea. During the brooding process, penguins will stop their normal activities, focusing only on protecting eggs. They use fat stored in the body to maintain strength. Usually, male penguins will lose half of their body weight after this process. At the end of the two-month period, the male penguin and female will rotate their roles to ensure their own health.

The way of talking penguins

In the penguin social community, they communicate and exchange information with each other through body language by using their heads and flippers. In particular, for penguins, researchers are surprised and surprised by their affections in their mother-child relationship. When children lose their children or their children die, they will find ways to 'kidnap' their children from other families. The most plausible reason is probably because the mothers cannot bear the pain of losing their children and must deceive themselves.

The ability to swim champion

Penguins can swim about 15 miles an hour far beyond the Michael Phelps swimming international Olympic gold medal with 4.7 miles per hour. They can dive underwater for about 20 minutes. Normally, small penguins dive in depth, only hold for about 1-2 minutes to search for prey. However, for larger species, they can dive to the depth needed in their abilities, including the emperor penguin with a record of diving to 565m.

Ability to camouflage when hunting

It is no coincidence that the penguin has a special coat in front of the white belly and the back is dark. It is a way to disguise the prey of the penguin. Black to hide when diving into the sea after dark, white to hide on the ice or cold white snow.

Penguins have no external genitalia, so the eye cannot distinguish between females and males. Only when checking chromosomes can they determine their gender. In particular, the population of penguin species also appears homosexual. At the wild park of Bremerhaven, northern Germany, two male penguins hatched an egg together, behaving like couples.
