What are the habits of animals when they hibernate? How do animals hibernate?

The methods of animal hibernation include collective hibernation and individual hibernation, collective hibernation is a group of animals gathering together to warm up and hibernating, such as snakes; Individuals hibernate by finding a place to hibernate on their own, such as a tortoise.

Hibernating animals can be roughly divided into two categories, one is amphibians and reptiles. Amphibians and reptiles such as frogs, snakes, and turtles are ectotherms, and when the weather is cold, they cannot move and enter a state of hibernation.

The other group is mammals. Mammals are further divided into two types: bear and squirrel. Most hibernating animals use pre-stored fat (equivalent to 30%-40% of body weight) for energy during hibernation.

When the outside temperature drops, they lower their body temperature. Reducing the number of pulses and breaths saves energy, but the body temperature of bear-hibernating animals does not drop much, staying around 38°C or 30°C. Why is that?

It turns out that bears are huge, and it takes a long time for their body temperature to rise up after it drops. In addition, bears have a "trick" that doesn't have to be so energy-efficient. That is, it never excretes during hibernation.

If urine is excreted, nitrogen compounds are excreted from the body, and instead of urinating, bears use the kidney wall to absorb them and reuse them as nutrients. Now some scientists have noticed this in bears"Trick", is exploring how it can be used to ** people with kidney disease.

So, do small mammals with squirrel animals also have this "trick"? Unfortunately they don't. Some of these animals need to dig holes in the ground to create a hole that can safely accommodate their bodies during hibernation, so they don't weigh much, up to 9 kilograms.

Animals such as bats have to "get up" from time to time to drain their feces and urine. But like bears, they store enough fat for energy first, so they don't eat or drink during hibernation. They are occasionally found storing food, but that is in case of famine when they wake up from hibernation too early in the spring.

However, animals like voles are still inseparable from food during hibernation. They wake up every 10 days during hibernation to excrete, then eat some food before going back to sleep. Their body temperature drops from 37°C-38°C to 8-10°C, and in some cases, even down.

What happens to these animals if the temperature is too low during hibernation? Generally, because their hibernation site is underground, it is difficult for the temperature to drop below 0 °C, but if the temperature of the hibernation site drops to about -10C, they will get up and shake the muscles of the body, so that the body produces heat, however, if they have to do so, it will consume physical strength, so they are very careful when choosing a hibernation place, and they should consider many things, neither too cold nor too hot.

In fact, the behavior of animals in hibernation has its own characteristics.

Many small mammals, such as baby hamsters and squirrels, exhibit a "dormant" state of light sleep.

After sleeping for a while, you will wake up and eat something, and then then turn your head back to sleep.

This probably has something to do with their small size and fast metabolism.

Bears in large mammals hibernate when they eat abundantly, grow a thick body of fat, and help themselves survive a long hibernation.

Some bears give birth and nurse directly during hibernation.

Like a polar bear, it is quite easy to be a mother, during the hibernation period, you don't need to worry about feeding, and you can go directly to the baby when you wake up and drill out of the snow hole. （23333333）

Some snakes and lizards in reptiles do not choose to eat a lot when they hibernate but choose to eat less or not at all, but they occasionally drink some water before hibernating.

Amphibians such as frogs leave the pond and dig a burrow in the dirt as a shelter to survive the winter. Some of them will lower their metabolism in the pond and hibernate them, which may cause it to die from lack of oxygen due to the freezing of the water surface.

Hibernation is more enlightening for humans, mainly in medicine.

On the one hand, there is organ transplantation, and the hypometabolic re-resuscitation process of hibernation can help the organs to be better preserved.

On the other hand, hibernation prolongs the lifespan of animals, which provides a key to the study of human longevity.

Hibernation is limited to birds and mammals. Hibernating species can be broadly divided into two groups, namely active hibernating animals and passive hibernating animals, the latter such as hamsters, and external factors including photoperiod, food, and outside temperature play a major role in the timing of this hibernation cycle event.

There are 3 types of hibernation.

The first is the hibernation of amphibians and reptiles such as snakes and frogs, whose body temperature is in harmony with the surrounding environment, and if the ambient temperature drops, the body temperature will drop and enter a state of hibernation, which cannot be adjusted.

The second type is squirrels and other animals whose body temperature is usually kept at a constant temperature, and when hibernating, their body temperature can be lowered to a temperature close to the surrounding environment, but in order to avoid freezing body fluids below 0, their body temperature is maintained at around 5.

The third type is bears, whose body temperature drops only a few degrees when hibernating, but can sleep without eating for a long time, which should be close to sleep and hibernation under strict classification.

What animals hibernate have characteristics, and what animals hibernate will have characteristics, such as snakes. He would lie down like a dead one, and turtles would be.

I think the big black bear in the Northeast hibernation is the most characteristic, he will find a tree hole, hide himself, when hungry will lick his big paws, until the weather warms up before coming out to feed.

1.The body temperature of the animals decreased significantly.

2.Blood cells will be greatly reduced.

3.The annual cycle of hibernating animals can be divided into non-hibernation season and hibernation season.

Snakes, of course
