Why can penguins survive in such cold weather?

Penguins, belonging to the order Penguins, are the oldest migratory birds and probably settled in Antarctica before the Earth put on ice armor. There are 18 species of penguins in the world, most of which are found in the Southern Hemisphere. On land, it's like he's wearing a tuxedo.

Like Western gentlemen, they swayed when they walked, and when they encountered danger, they fell and climbed, and they were embarrassed. But the penguin in the water is different, using its short wings to form a pair of powerful paddles. So many people may have this question, why can penguins survive in such cold weather?

Penguins usually live south of the equator, where it is rare to see it in human-like places. There are some penguins that live in cold places and some penguins that live in tropical places. But penguins don't like hot weather and can only be happy in cold climates. So in distant Antarctica.

In the icy ocean along the coast, there are the most penguins. Penguin habitats vary depending on the species and area of distribution. Emperor penguins prefer to inhabit ice shelves and sea ice, Adélie penguins and Jintu penguins can live on both sea ice and land in ice-free areas, and penguins in the sub-Antarctic prefer to inhabit rocks in ice-free areas and often build their nests with rocks.

Why aren't penguins afraid of the cold? First of all, let's start with its morphological structure. Geometrically, the specific surface area of a spherical object.

is the minimal. The smallest area per second will mean that there is a minimum contact area with the outside world, and with the smallest possible heat dissipation area, there will be the smallest heat dissipation speed. Judging from the penguin's body form, its body has evolved as close to a sphere as possible, with a short and thick body, a short and thick neck, and short legs and feet that can reach under the belly, reducing the area of contact with the outside world and minimizing the loss of heat.

Penguins living near the Antarctic are covered with dense and thick feathers, and the tips of the feathers are curved, like the scales of a fish, so that even water cannot penetrate them, and they can also resist the blowing of strong winds. There is also a dense pile underneath the feathers, just like the best quality cardigan. With such good feathers, the penguin is like wearing a thick down coat, which should be waterproof and insulated, and not afraid of the cold.

At the same time, Qi Yao's body has thick fat. It can also play a role in heat preservation. In Antarctica, especially in the harsh weather environment, penguins live in groups, and the colony is constantly moving, and the inside and outside are constantly exchanged, so that they can warm each other and minimize the loss of heat.

The penguin's tiny wings allow it to swim like a flight in the water, and it is fast enough to hunt krill in the water.

and other small fish to provide themselves with energy. So penguins can survive in cold weather.

Different creatures have different physiques, and it is normal for penguins to be born with resistance to cold.

Penguins' subcutaneous fat is very thick, which allows them to survive the extreme weather of Antarctica, plus the cold Antarctica has krill and other suitable foods for penguins, which can also ensure penguin food**.

That's because penguins have a thick layer of fat, and their fur is also hardy.

Penguins are not afraid of the cold for the following reasons:

The first is the feathers on the outside of the body. If you look closely, you will see that the feathers are overlapping and intertwined. Not to mention the cold wind, even the sea is difficult to break through the defense line of these feathers.

The second is the fluff that clings to the body. Those fluffs are very dense. Penguins wear top-of-the-line down jackets and are certainly not afraid of the cold.

Other reasons

In addition to these two pieces, the penguin also has a thick layer of fat in it. This fat layer is the big fat meat, which can generate heat and keep the penguins warm.

Penguins have evolved over a long period of time to develop a unique vascular system. The arteries and veins are staggered, and the cold blood flowing back to the heart and the blood flowing out of the heart can be exchanged for heat, thus ensuring the temperature of the blood.

There are many reasons why penguins can survive in Antarctica, such as their feathers and thick subcutaneous fat to keep them warm, and the penguins huddle together to keep warm.

1. Penguins have survived in Antarctica for a long time, and after a long period of evolution, they have a very thick subcutaneous fat. Penguins have survived in Antarctica for thousands of years, tens of thousands of years, and have survived for so long, penguins have changed to a great extent, for example, penguins were originally able to fly, but in Antarctica, in order to better adapt to the local environment and avoid the pursuit of natural enemies, penguins have gradually evolved into an animal that hunts in the sea, and because the climate in Antarctica is relatively cold, penguins have slowly formed a very thick subcutaneous fat to keep themselves warm.

2. Penguins are social animals, and when the weather is too cold, they will huddle together to keep warm. Penguins are social animals, they don't live alone, Antarctica is sometimes very cold, at that time, penguins will gather in a pile, in a spiral shape, and then a circle of cycles, to help each penguin warm, to ensure that the penguin will not freeze to death because it is too cold, at this point, penguins are still very united, and I think this is also a function that they have evolved over a long period of time.

3. Antarctica is not so cold all year round. We all know that there are polar days and polar nights at the north and south poles of the earth, during the polar day, the Antarctic is not as cold as we imagined, and even warmer than many places, the Antarctic is cold mainly in the polar night, at that time the southern hemisphere enters winter, the Antarctic snows, and there is no sun exposure, it will be very cold, but we also said the penguin prevention method above, so even if the Antarctic of the polar night is very cold, most penguins can still carry it.

In summary, the main reason why penguins can survive in Antarctica is because they have a thick subcutaneous fat that helps them keep warm, and they also work as a team to help keep themselves warm, and it is for these reasons that penguins can survive in the cold Antarctic.

Penguins actually have a lot of fat in their bodies, so their ability to keep warm is very strong, and secondly, penguins have a good down content on their body feathers, so they can survive in cold environments.

Because penguins have lived in Antarctica for a long time, they have adapted to the environment here, and their feathers are densely overlapped to prevent water from soaking and protect against the cold. The subcutaneous fat is also very thick, providing a constant source of energy for the penguins.

Penguins live in Antarctica, and the reason why they can survive in such cold conditions is because of the very thick subcutaneous fat. Able to withstand such cold weather.

Hello! Because penguins are the oldest settlers of Antarctica. One is that the penguin has adapted to the harsh environment of Antarctica, its feathers are particularly thick, its body fat is abundant, and it has good temperature retention or shouting, so it is not afraid of cold.

The second is that there are a lot of small fish and krill in Antarctic waters, and there is a lot of food. The third is that in Antarctica, it has relatively few natural predators, and it will not affect its survival. Therefore, we think that Antarctica, where the environment is harsh, is its "paradise"!

1. The penguin is one of the oldest migratory birds, and it probably settled in Antarctica before it put on ice armor.

2. Although the Antarctic is extremely cold, the penguins have been tempered by tens of millions of years of snowstorms, and the feathers on their whole bodies have become overlapping and densely connected scales. This special feather coat is not spring land, but the sea water is difficult to penetrate, and it is not intended to break through its thermal insulation defense line.

3. Antarctica has a lot of land and a wide sea surface, and the abundant marine plankton has become abundant food for penguins. Penguins are a type of bird, so penguins do not have teeth. Penguins have barbs on their tongues and palate to accommodate eating food such as fish and shrimp, but they are not teeth.

The world is so big, why do penguins choose the cold Antarctica to settle down? It turns out that a long, long time ago, Antarctica was not a place of ice and snow, and the ancestors of penguins lived there. Later, the Antarctic became colder and colder, and many animals left because they could not bear the cold, but as the penguin adapted, its feathers became densely overlapped, which not only prevented the sea water from soaking, but also resisted the cold winds, so that it could continue to stay in Antarctica.

In addition, there are no ferocious carnivorous beasts in Antarctica, which makes the survival of penguins another guarantee of safety.

Antarctica is the coldest place on Earth, and the lowest temperature ever measured here is o c. Bear.

The penguins that live here are covered with dense and thick feathers, and the tips of the feathers are curved, like those on the roof.

The tiles are pressed one layer at a time, and even water can't penetrate them. There are also dense fluff under the layers of feathers, elephants.

It is the best quality cardigan. With such good feathers, the penguin is like wearing a thick down coat, and it is guarded.

Water insulation, not afraid of cold. At the same time, penguins have a thick body of fat, which can also play a role in heat preservation.
