Do polar bears hibernate? How do polar bears spend the winter?

The polar bear is an animal of the Ursidae family and the largest land carnivore in the world. It is also known as the white bear. As global temperatures rise, the floating ice in the Arctic has gradually begun to melt. The former home of the polar bear has been destroyed to a certain extent. It is very likely to become extinct in the near future and needs human protection. Protecting the ecological environment is the responsibility of all of us.

Do polar bears hibernate?

Polar bears need to hibernate. Although they live in the Arctic, they will hibernate once the harsh winter arrives, because food is scarce at this time, and hibernation can reduce energy consumption. In addition, polar bears are in a state of half-sleep and half-sleep during hibernation, and their vigilance is relatively high.

In our lives, there are four seasons in a year: spring, summer, autumn and winter. Summer is very hot and winter is relatively cold. Therefore, every winter we need to wear thick clothes to resist the cold. At this time, some animals in nature will also hibernate.

We all know that polar bears live in the Arctic. The temperature of their living environment is relatively low. Many people think that they do not need to hibernate. In fact, this is wrong. Polar bears also hibernate in the severe winter in the Arctic, but their hibernation is somewhat different from that of other animals.

Polar bears are very alert, and although they hibernate, they also stay awake during the process, in a state of half-sleep. The reason why they hibernate is that in severe cold weather, food and other daily necessities are very scarce, and hibernation can avoid energy consumption and is more conducive to survival.

How do polar bears spend the winter?

Before hibernation, they have to do a series of preparations. In late autumn, polar bears spend twenty hours a day foraging in the mountains and forests for food, and eat for about a month. In this way, when they enter the cave for hibernation, they have stored enough fat, a full 40 kilograms. After hibernation, its energy source is the fat stored in the body. When the weather gets warmer, the bear wakes up from hibernation. It will first use its tongue to lick the moss on the rocks to clear the debris in the stomach and intestines, and strengthen the gastrointestinal function that has not been used for a long time, and then go hunting.

Will polar bears attack humans randomly?

Polar bears will not attack humans at will. Polar bears are a species of animal in the Ursidae family and the largest land carnivore in the world. They are also known as white bears. Their skin is black, and because their hair is transparent, they usually appear white, but they can also appear yellow. They are huge and ferocious.

Polar bears have the same vision and hearing as humans, but their sense of smell is extremely sensitive, 7 times that of dogs. They can run at a maximum speed of 60km/h, 1.5 times that of the world's 100-meter champion. As global temperatures rise, the floating ice in the Arctic is gradually melting, and the polar bears' former homes have been destroyed to a certain extent. They are likely to become extinct in the near future and need human protection.
