When you think of penguins, what comes to mind is an animal that walks around, swaying and swaying, looking like a walking untouchable.

They wear black leather coats all year round, except that these coats do not cover their snowy white bellies.

They usually like to walk in a line, and from a distance, you can often see rows of round, chubby little guys.

Because of their lovely appearance, many people are very fond of them, these seemingly cute and well-behaved animals, have a lot of wonderful knowledge.

Adult penguins have black heads and backs, and white bellies.

The little penguins are different, their whole body is gray, and because they are smaller, they look like little gray fluff balls.

Someone once experimented by mixing a penguin-shaped camera into a penguin colony.

Since the camera was lying on its back, it was different from the normal standing posture of penguins, which made many penguins come up to watch.

Many penguins even started to imitate the camera and started to walk on the ground on their bellies.

Here let's get to know this group of cute and cute little animals. Today's penguins live in the Antarctic, but their ancestors, the tube-nosed animals, did not grow in the Antarctic.

They grew south of the equator.

Scientists speculate that the reason penguins did not move further north in the northern hemisphere may be because they could not tolerate the warm tropical waters.

Penguins have a unique structure.

Their feathers are three to four times denser than those of birds of the same size, and these feathers regulate body temperature.

Although penguins have essentially the same feet as other birds, their bones are hard, relatively short, and flat.

This feature, combined with short paddle-like wings, allows penguins to "fly" underwater.

Although the Antarctic is very cold, penguins have experienced tens of millions of years of blizzards that have turned their feathers into overlapping, tightly connected scales.

This special coating not only makes it difficult for seawater to penetrate, but even at temperatures of nearly 100 degrees Celsius below zero, it cannot break through its insulating defenses.

There is a lot of land in Antarctica, where the sea is very wide, and the rich marine plankton has become a rich food for penguins.

The penguin is one of the oldest birds that can swim. Antarctica has vast land masses and wide oceans with abundant planktonic salt glands to excrete excess salt.

Penguins' eyes can see underwater and above the water because their corneas are flat.

The eyes can transmit images to the brain for tele-imaging integration, thus enabling tele-imaging capabilities.

Penguins do not have teeth and rely on the barbs on their tongues to eat, which are ideal for biting small fish and shrimp.

It is important to remember that penguins are toothless creatures.

Through the above introduction, we are sure you have a better understanding of penguins.

Penguins like to live in groups, and not a small pile huddled together, but tens of thousands or even hundreds of thousands huddled together for warmth.

So sometimes the penguins crowded in the middle will be very hot, thinking of squeezing out to breathe the cold air.

We never thought they would be too hot in the cold Antarctic.
