What are the tricks of animals to survive the winter, and what are the ways for animals to spend the

The hibernation of animals is really different, and the snail seals the shell with its own slime. The vast majority of insects, when winter comes, are not "adults" or "larvae", but hibernate in the form of "pupa" or "eggs". Bears breathe normally during hibernation and sometimes wander outside for a few days before returning.

Female bears hibernate and let the snow cover their bodies. Once it wakes up, it will be lying next to it 1 or 2 innocent and lively cubs, apparently born from hibernation.

Squirrels sleep even deader. Someone once dug a hibernating squirrel out of a tree hole, and its head seemed to be broken, and no matter how much one shook it, it would never open its eyes, let alone move around. Put it on the table, and you can't wake up with a needle.

It is only by heating it in a stove that it moves leisurely, and it takes a long time.

When the hedgehog hibernates, he even stops breathing. It turns out that it has a piece of cartilage in its throat that separates the mouth from the throat and tightens the entrance to the trachea. Biologists once brought a hibernating hedgehog and soaked it in warm water for half an hour before it woke up.

Animals hibernate for varying lengths of time. The Oriental marmot in northeastern Siberia and the hedgehog in our country can sleep for more than 200 days at a time, and in Canada, some mountain mice hibernate for up to half a year, while the sable in the Soviet Union only hibernates for 20 days a year.

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

The main ways for animals to survive the winter are: storing food, hibernating, migrating, and moulting.

A thing that looks very similar to a snail is called a slug, he lives in a damp and dark place, the only difference between him and a snail is that he has no shell, his tentacles can also be retracted into it, it is very cute, and the other party that crawls over also has bright mucus, but his holy body is rich in water, if you sprinkle some salt on his body, after a while he will become a puddle of water and a layer of skin!

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 let their eggs survive the winter, such as locusts, butterflies, etc.

When winter comes, how to survive the winter is not only a problem that human beings need to consider, but also a problem that many creatures in nature need to face, especially in the nature of the survival of the fittest. In the cold winter, humans can choose to add clothes and a stove to protect themselves from the cold, and animals have their own unique tips for keeping out the cold. So, what are some of the ways animals spend the winter?

Let's take a look. The winters on the Tibetan Plateau are very harsh, with high cold and low oxygen, and food is still very scarce, so such a harsh environment is a harsh physiological challenge for the survival of animals. In order to survive the winter, the animals can be said to have their own tricks.

Some species, such as swallows, fly to the warmer south for the winter before the onset of winter; Some species, such as marmots, squirrels, hedgehogs, bats, hummingbirds, etc., will hibernate (or hibern) to survive the harsh winter. Some species survive the harsh winter by improving their physiological resistance or behavioral regulation, such as improving their ability to generate heat, building warm nests, and storing enough food. 1. Walk on your heels.

In addition to having a special circulatory system on their feet and fins, emperor penguins often lean back to lift their toes off the ice, and their wedge-shaped tails keep them balanced and not frozen when their tails touch the ice, because there is no blood flowing through their tail feathers.

Heating method. Second, the heating method of "rejuvenating the teacher and moving the people".

The bee family's way of heating is a frictional tactic that stirs up the crowd. The temperature outside drops, which is the information of the battle, and the battle curtain will slowly open immediately. When the bees enter the battlefield, they first surround the queen bee, crawling around the nest, keeping busy, relying on the energy generated by the movement to keep warm.

If the temperature drops again, the bees close to the queen bee break their fast and devour the honey in large gulps. Because they can't stand the cold, they desperately drill into it to squeeze out the bees in the inner layer, so that the bees go in and out, and the cycle continues, so that the hive retains the temperature through friction technology.

3. Warm clothing.

In the Arctic Circle, winter temperatures drop to -40, and it is extremely difficult for humans to live in such harsh conditions, yet there are still a large number of warm-blooded animals.

Cold. Polar bears and arctic foxes are the "representative species" of the Arctic climate. They "wear" a thick double layer of fur.

Some researchers have found that each white hair of polar bears is empty in the middle, and there is a thin stamen in the middle of the hole, which can absorb ultraviolet rays, and the light passes through the capillary to the epidermis, and the epidermis converts light energy into heat energy for storage. Polar bear fur has been shown to be 95% effective at converting ultraviolet light into heat.

It is precisely by relying on this magical ability that polar bears can still live and reproduce leisurely in the ice and snow of the Arctic region.

1. Winter animals have winter hibernation, migration, moulting, storage of food over the front crack winter, egg laying for the winter, hiding in a safe place for the winter, etc.

2. There are many animals in the world, and each animal has a different way of wintering.

3. Snakes hibernate for the winter, geese migrate for the winter, rabbits for the winter, bees for the winter to store food, praying mantis to lay eggs for the winter, and mosquitoes to hide from the late draft for the winter in a safe place.

1. Snakes: hibernates, hides in holes and sleeps in winter, and does not wake up until spring, for such a long time, does not eat, drink, move, and slowly consumes body fat to survive the cold winter.

2. Swallows: Migrating to their places of residence, they will fly to the warm south to spend the winter before winter arrives.

3. Fox: Before the arrival of winter, a part of the food will be stored. Before autumn, they will try to eat as much as possible, desperately prey, and accumulate a layer of fat on their body. Then there will be a big moult, and the hair will become longer and thicker.

4. Squirrels: They will collect a large amount of hay before the arrival of winter, frequently forage and store rations for the whole winter, and then look for a place to live in winter in tree hollows or rock corners.

5. Praying mantis: lay eggs in autumn, let the eggs spend the winter on the branches, grass and soil, the shape of the eggs is protected by a special egg bag, not afraid of the cold, and when spring comes, the larvae will crawl out of the eggs.

1. Winter animals have winter hibernation, migration, moulting, storing food for winter, laying eggs for winter, hiding in a safe place for the old and regretting the winter.

2. There are many animals in the world, and each animal has a different way of wintering.

3. Snakes hibernate for the winter, geese migrate for the winter, rabbits for the moult for the winter, honey imitation bees for the winter, praying mantis for the winter, and chain mosquitoes for the winter.
