How do animals protect themselves from the cold in winter?

How do animals survive the winter without autumn pants? The "cold technique" of different animals is breathtaking.

1.Arctic foxes and polar bears living in the Arctic region have very rich fur, which plays a good role in maintaining body temperature and can effectively resist the severe cold of the Arctic.

2.Pinnipods such as seals, which live in the cold waters of the polar regions, have a thick coat and subcutaneous fat to keep them warm.

3.Burrowing mammals such as rodents are also protected from the cold. Rodents, pigs, bats, etc., often adopt a social way to greatly reduce the heat demand of each individual and protect against cold.

4.Bears, bats, and weasels can also hibernate to ward off the winter cold.

Emperor penguins are the animals that best illustrate this. Emperor penguins living in Antarctica are accustomed to low temperatures, but they are used to cold winds and low temperatures. The best way for penguins to breed in such a cold place is always to huddle thousands of them together to form a solid barrier to reduce heat loss.

When emperor penguins enter the interior to breed, heavy snowstorms there can sometimes bring temperatures down to minus 70 degrees Celsius. At this time, their method of heating is to huddle together. They walk in circles to keep warm, until they turn to the core, and then from the center to the outside, so that they stay warm and everyone does not freeze to death.

Thermal underwear made by whales.

Mammals like whales, seals and dolphins, which spend most or all of their time in the sea, maintain their body temperature with special high-grade fat "underwear". Blublem is a layer of heavy fat "underwear" that wraps around the entire body, and the mass can reach half of body weight! This layer of fat contains fine vascular tissue, which not only helps maintain body temperature, but also provides an important energy reserve for many marine animals that travel long distances to breed and feed.

In addition to this, this layer of fat helps fast-swimming animals to shape their bodies into streamlining, reducing the amount of energy expended when swimming in the water while increasing their speed. The colder the sea water that the animal inhabits, the thicker its own fat becomes. Blublem is obtained by sucking the mother's milk.

Butterflies, birds, and beasts love to migrate.

Another way to escape the cold is to "run away", which is practiced by many animals, of course, the vast majority of them are migrating like birds. Hearing the call of the Brown Warbler is actually a sign of the arrival of spring. But sometimes it's hard to notice that they slip away unconsciously.

The migration of swallows is very noticeable: when autumn comes, they will stand in flocks on the ** line and set off for the south, where they will look for more suitable weather for them.

In addition to birds, some other animals also have migratory habits: gray whales at the poles swim to the tropics to mate; Large ungulated mammals such as Arctic reindeer and African wildebeest travel far and wide in search of fresh grasslands; Even butterflies are no exception: the yellow and black North American butterflies make a massive trip each autumn to Mexico in a spectacular procession of millions of butterflies.

The musk ox has a thick layer of hair, so it gives a very warm and cozy feeling. The behemoth also has a thick layer of insulating hair, so it can withstand the bitter cold of the Arctic. Hunting once brought musk oxen to the brink of extinction, but conservation measures have led to a resurgence in their populations and the reintroduction of musk oxen to their former habitats, such as Alaska.

Eat more chicken, duck: pork is to keep warm, don't eat air conditioning, so for the strong body, there is nothing to do, especially in winter, things that are afraid of cold will go to keep warm.

Big cats are fine.

1. Hibernation (including false hibernation): bears, frogs, turtles, bats, snakes, (the last two also belong to social hibernation).

2. Those who survive the winter by storing food: squirrels and rabbits.

3. Migrating for the winter: geese, swallows and other birds.

4. Moulting for the winter: white rabbits, sika deer, etc.

5. Insects and animals let their eggs survive the winter, such as locusts, butterflies, etc.

1. Use exercise to keep out the cold. For example, tigers run to keep out the cold, and gorillas move rocks to keep out the cold.

2. Hibernate to keep out the cold. For example, frogs and snakes hibernate to keep out the cold.

3. Mammals can protect themselves from the cold by regulating themselves through nerve-humoral humulants.

According to fossil research, the first animals to appear on Earth originated from the ocean. After a long geological period, early marine animals gradually evolved into various branches, enriching the early life forms on earth.

Prehistoric animals appeared before the advent of humans and flourished during their respective periods of activity. Later, they became extinct one after another in a constantly changing environment. However, the animals on Earth continue to evolve and reproduce from the lower to the higher, from the simple to the complex, and have the diversity they have today.
