Why are polar bears not afraid of the cold? Why don't polar bears eat penguins?

Polar bears and penguins are two animals that we are familiar with, living in extremely cold environments. Polar bears are much taller and more ferocious than penguins, but we have not heard of polar bears eating penguins. So why don't polar bears eat penguins? In fact, after we understand their living environment, we will no longer ask this question. Try it and see if it is true!

Why polar bears are not afraid of the cold

Polar bears are not afraid of cold because their fur has a strong ability to absorb sunlight and transfer heat throughout the body. At the same time, this layer of fur has a strong heat-insulating effect, which can prevent the temperature in the polar bear's body from dissipating. In addition, the food that polar bears eat is also high in calories, which can help polar bears better keep their bodies warm.

The North and South Poles are the two places with the lowest temperatures in the world, and polar bears live in the South Pole, where the temperature can drop to dozens of degrees Celsius below zero. If humans are exposed to such an environment without wearing any equipment, they would not be able to survive at all. So why can polar bears survive normally in the Arctic without fear of the cold?

There are many reasons why polar bears are not afraid of the cold. One of the most representative reasons is that the polar bears' hair can absorb the sun's rays very well and transfer its heat throughout the body. At the same time, this layer of hair also has a good heat-insulating effect, which can effectively prevent the polar bear's internal body temperature from dropping quickly.

In addition, the food polar bears eat has a lot to do with their fearlessness of cold. Polar bears are relatively picky eaters, and most of the food they eat has high calorie content, which can help polar bears keep their bodies warm.

Why don't polar bears eat penguins?

We have the impression that polar bears don't eat penguins because polar bears live in the Arctic and penguins live in the Antarctic, so there is no way for them to prey on each other. The main food of polar bears in the Arctic is seals, walruses, seabirds, and small mammals such as avocados. They only eat the fat parts of these animals to provide themselves with sufficient calories.

The reason why polar bears do not eat penguins is that they live in completely different regions. Polar bears live in the northernmost part of the earth - the Arctic, while penguins live in the southernmost part of the earth - Antarctica, so polar bears have no way to prey on penguins.

In the Arctic region, seals, walruses, seabirds and various small mammals are the main food of polar bears. When eating these animals, polar bears only eat the fat part of their bodies. They do this to replenish themselves with enough calories so that they can survive better in low temperature environments.

What color is a polar bear's skin?

Polar bears have black skin, and their white fur is just a visual effect due to the refraction of light. In fact, polar bears are hollow and transparent. Polar bears are huge and fierce. They are the largest carnivores on land. They have extremely strong vision, hearing, and smell, and can run at speeds of up to 60 kilometers per hour.

Polar bears are a special species that can only be seen in the Arctic. The polar bears we usually see on TV, in photos and even in animations often have white fur, so many people think that polar bears' skin is also white. In fact, this guess is wrong.

The polar bear's real skin color is black, and its hair actually has no color, but is hollow and transparent. It's just that its hair refracts the surrounding light, so it gives us the illusion that its hair is white.

The polar bear is currently the largest land carnivore in the world. It not only has a huge physique, but also a very ferocious personality. At the same time, its vision, hearing, and sense of smell are also very powerful. It can run at a speed of up to 60 kilometers per hour, making it an excellent hunter.
