Which animal hibernates the longest? Which animals hibernate

The animals that hibernate the longest in the world hibernate for up to nine months and often starve to death while sleeping.

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.

Dormice hibernate for the longest time.

Dormice, sleeping soundly for 5-6 months of the year. (from October to April) is hibernating. 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, with small bodies (60 to 190 mm long), short forelimbs, large eyes, hairy tails, long whiskers, and no cecum. 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.

There are 28 species of dormice, the smallest of which grow in Africa, Asia and Europe. Dormice eat a lot, usually weighing between 15 and 22 grams during the summer solstice and autumn; However, before winter begins, dormice can quickly rise to 25 to 40 grams. The fat and energy stored 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.

A dormouse has a lifespan of only five years and spends three-quarters of its life sleeping, so both baby dormice and mother dormice must store enough fat in the shortest possible time to maintain the energy needed for a long hibernation life.

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.

Dormice are the animals that hibernate the longest in the world.

Dormice, belonging to the rodent order, dormouse family, are short in size and resemble the appearance of the Lianghuai filial piety rat family. They usually live for 5 years, but sleep for 3 4 of the time, that is, dormice hibernate for about 9 months of the year in spring, late autumn, and winter.

They don't store food for the winter like other rodents do, but try to eat as much as possible to store fat for the winter. During hibernation, dormice lose nearly half of their body weight, their body temperature drops, and their breathing slows down.

Habits

Despite its lethargy, dormice have a peculiar ability to escape. If its tail is caught, it will quickly shed its outer layer**, leaving the enemy with only a little fur and itself fleeing.

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 they also depend on the dense foliage of hawthorn and black plums.

The animal with the longest hibernation time is the dormouse, the appearance of the dormouse is very similar to the mouse, this animal hibernates for five to six months a year, which can be said to be very long, and half a year is spent in hibernation. Here's a look at the "animals that hibernate the longest".

1. Name: Dormouse is also called forest dormouse, and its name is derived from its habit of liking sleep.

2. Sleep to death: The dormouse may be sleepy at any time, even in some noisy environments, it can fall asleep, and even starve to death in sleep.

3. Escape skills: Although dormice are very lazy, they also have their own unique escape skills, and when they are caught by the enemy, they can shed their skin and escape.

4. Lifespan: Generally speaking, dormice live for about five years, but three-fifths of their lives are spent in sleep.

Now that we know what the animals that hibernate the longest are, let's talk about why animals hibernate. Animal hibernation is generally done for the sake of energy storage, as sleeping is the method that consumes the least amount of energy.
