What animals hibernate the longest and which ones hibernate

The one that hibernates the longest is when pushing dormice.

It hibernates for 5-6 months a year (from October to April).

According to reports, a dormouse in the United Kingdom has been sleeping soundly for 6 months and 23 days, which is the longest hibernation animal in the world.

Dormice are morphologically and structurally intermediate between rats and squirrels, and their common characteristics are small bodies (60 to 190 mm long), short forelimbs, large eyes, large, round ears, hairy tails, long whiskers, and no cecum.

It is an arboreal animal that nests in tree cavities. Sleep in tree hollows or jungles during the day and go out foraging at night. They mainly eat berries, nuts, grains, etc., and sometimes a little bit of insects.

Probably a mountain rat in Canada.

In Canada, some mountain mice hibernate for up to half a year. When winter comes, they dig tunnels, burrow into burrows, and curl up in a ball. Their breathing slows down to almost cease, their pulse becomes extremely weak, and their body temperature plummets to 5.

At this time, even if you kick it, it will not have any reaction, it will be like dead, but in fact it is alive.

The oriental marmot in northeastern Siberia and the hedgehog in our country can sleep for more than 200 days in a single hibernation.

It's a frog! It must be a frog!

I heard that there was a frog that hibernated for 2 million years.

Hibernating animals have:Hedgehog, skunks, bats, snakes, frogs, turtles, ants, snails, round bears,Toad, earthworms, squirrels, etc. There are three main types of hibernation animals, the first is amphibian reptiles, the second is squirrel-like animals, and the third is bears, when bears hibernate, their body temperature drops to a few degrees and can go without food for a long time.

Hibernation can be divided into three stages.

Falling asleep is the process when the animal's body temperature begins to stabilize close to the ambient temperature. Approximately from one to a few days. The stage of deep sleep is variable and can usually last for several months. And the animal's respiration will be significantly reduced. At the same time, the circulatory system.

There will also be significant changes, and the third stage is sleeping, which can also awaken hibernating animals for other reasons other than self-arousal.

Hibernating animals use physiological changes to seal their lives against harsh environmental influences, and the form of animal hibernation is basically different according to the different types of animals that change temperature and are homeothermic. Hibernation is also called winter stinging.

This is a dormant type that is the case for certain animals that are cold in winter and have insufficient food. An adaptive response to a variety of adverse natural environments.

There are hundreds of species of hibernation animals, the most common of which are ground squirrels, hedgehogs, frogs, snakes, bears, snakes, crocodiles, turtles, etc.

Hibernation (aka'Winter sting') is a state in which an extreme but regulated decline in body temperature, metabolism, and other biologic activities is observed as an adaptation to reduced energy expenditure. 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 determining the timing of the hibernation period events of the hibernation group.

The hibernation of animals begins in October, and the annual cycle of hibernating animals can be divided into non-hibernation season (reproductive season) and hibernation season. The hedgehogs in Beijing go to sleep at the end of March, and immediately carry out reproductive activities, and after completing reproduction, they will enter the fattening period, until the beginning of October, which is the non-hibernation season; October and March are hibernation seasons.

At this time, the animal curls up, does not eat or drink, and the metabolic rate is reduced to a minimum level. During these two seasons, the physiological states of the animals are very different, but they are interdependent. Fattening at the end of the non-hibernation season stores energy for hibernation, and at the end of the hibernation season, the gonads begin to develop, and the animal can reproduce immediately after sleep.

Some animals that are not hardy to survive the cold season often hibernate have been called a habit of theirs. Every year around the time the frost falls, the temperature gradually decreases, and the frog chirping in the pond disappears; Meat-winged bats hang upside down on shady roof beams or cave walls. Begin its long sleep; Moles, hamsters, burrowing hares, hedgehogs, etc., also hide in burrows and enter a dormant state that does not eat or move.

The length of hibernation varies from animal to animal, and usually, the length of hibernation is related to environmental factors, dietary intake, species, etc. Here are some typical hibernation times for hibernating animals:

1.Most bats begin to hibernate in November-December each year and last for about 3-5 months.

2.Bears (e.g., black bears, brown bears, etc.) begin to retain fat and energy in the fall and go dormant during the winter, usually starting in November or December and lasting anywhere from 3-5 months.

3.Sand pigs accumulate fat during the dry summer months and hibernate for up to 8 months in the winter.

4.Badgers (e.g. the European badger) also undergo residual hibernation, usually starting in October and lasting 4-5 months.

It should be noted that although the above are typical hibernation animals, there are differences in the hibernation habits and timing of each animal, and the mechanism of hibernation and the factors affecting the scum are also very complex. If you want to know how long a particular animal hibernates, it is recommended to consult the relevant literature or consult a relevant professional.

The hibernation time varies from animal to animal and is not fixed. For example, hedgehogs go into hibernation when the temperature drops to 7°C and hibernate for up to 3 to 4 months, while squirrels can hibernate for up to 6 to 7 months.

Among the many hibernating animals, the one that hibernates for the longest time is the dormouse.

It hibernates for 5-6 months a year (from October to April), and it is reported that a dormouse in the UK has slept soundly for 6 months and 23 days, making it the longest hibernation animal in the world. Dormice are morphologically and structurally intermediate between rats and squirrels, and their common characteristics are small bodies (60 to 190 mm long), short forelimbs, large eyes, large, round ears, hairy tails, long stupid or whiskers, and no cecum.

It is an arboreal animal that nests in tree cavities. Sleep in tree hollows or jungles during the day and go out foraging at night. They mainly eat berries, nuts, grains, etc., and sometimes a little bit of insects.

Other hibernating animals

Arctic ground squirrels begin to hibernate in August, during which their body temperature will drop to about minus 3 degrees Celsius, their heartbeat is only 1 time per minute, and even the temperature of their brains and blood will drop below zero, but they will not freeze because of this, and by the end of April and early May of the following year, the northern Kaiwu polar squirrels will be active again after waking up.

Frogs are amphibians and cold-blooded animals, and their body temperature is affected by the air temperature, and as the temperature gets colder, their body temperature will gradually decrease. When the temperature drops to a certain level, the frog burrows into the dirt, does not eat or move, and sleeps to escape the cold. Lizards that live in cold regions will hibernate, most lizards live in the tropics and subtropics, and a few lizards native to temperate zones can hibernate.

The animal that hibernates the longest in the world is the dormouse.

As you can tell from the name, this is a very sleepy mouse. They spend five or six months of the year sleeping. Even if it's not hibernation time, they're always asleep.

When dormice hibernate, like other animals, they do not eat or drink, their various physiological functions are reduced to a minimum, their bodies become stiff, and even their breathing almost stops, even thunder cannot wake them up.

Dormice are small, with a body length of centimeters and a tail of centimeters, and weigh as little as 30 grams and as large as 100 grams. Dormice are similar in appearance to ordinary mice, with large black eyes, large, round ears, short forelimbs, and long squirrel-like hair. Dormice nest between tree rights, and usually inhabit trees, and eat mainly berries, nuts, grains and some small insects.

The habits of dormice

Dormice are found in Europe and Asia and in the southern part of the Sahara in Africa. They live mainly on hazelnuts, blackberries, roses, elderberries and other street trees, but also depend on the dense foliage of hawthorn and black plums. Dormice usually weigh between 15 and 22 grams in autumn.

However, before winter begins, dormice will quickly rise to 25 to 40 grams. The pre-stored fat and energy in the body allow the dormouse to survive the long and harsh winter in its sleep; When spring comes, your weight will return to your normal weight in early fall. The sense of smell is very good, and no matter how far away from the nest you can find it.
