There are many species in nature, which together form a big home, and each animal has its own habits, of which hibernation is the habit of some animals, and the phenomenon of animal hibernation is very wonderful.
Do you know what animals in the world have hibernated the longest?
The answer is: sleeping mice.
The life span of the sleeping mouse is generally about five years, every spring, late autumn and winter, nine months are spent in hibernation, and three-quarters of its life is sleeping, which is really sleeping with life!

Today Xiaobian takes you to uncover the "little secret" of animal hibernation.
"Hibernation" is the ability of animals to adapt to poor external environmental conditions and evolved, the main reason for animal hibernation is the harsh winter climate, lack of food, hibernation when the animal's life activities are in a state of extreme reduction.
Hibernation is a survival strategy for animals
Small into science time
Frogs, snakes, turtles and other warm animals can not maintain their own body temperature, their body temperature will also decline with the decrease in temperature, therefore, in the winter will enter hibernation, hibernation for warm animals is an adaptation to low temperature environmental conditions.
Birds and mammals are thermostatic animals, and their bodies can maintain a certain temperature regardless of the temperature, however, some thermostatic animals also need to hibernate. For example, bears, sleeping mice, bats, etc., the main reason for their hibernation is the lack of food in winter, and the countermeasures taken without full guarantee are also a way of survival.
Small family animals do not hibernate Oh ~
To say that the most afraid of cold animals in winter, to belong to the two reptiles, they are very sensitive to temperature, winter, thermal insulation measures must not be sloppy.
01
Turtles do not hibernate
Turtle is a warm animal, activity is greatly affected by temperature, before the arrival of winter, the ambient temperature is lower than 18 degrees Celsius, the radiator comes in handy, the indoor temperature can reach 24 ~ 26 degrees or more, the turtle rests and moves in the warm room.
The turtles' greenhouses
Hey, actually I'm still climbing pretty fast
02
Snakes do not hibernate
Snakes are cold-blooded animals, and in the wild conditions, snakes go into hibernation in the winter, relying on fat burning in the body to maintain the substances needed for life activities. Heating equipment is installed in the snake's room, and the snake does not hibernate under constant temperature conditions.
Just look at you quietly
03
Bears do not hibernate
In the wild, in addition to living in the tropics, subtropical Malay bears do not hibernate, other bears have the habit of hibernation, due to the lack of food in winter, in the autumn, the bear will eat a lot of fat storage, in a semi-sleep state, body temperature, heart rate will decline, in order to save the body's metabolism.
Standing tall we can see far
Because the bears in the zoo have plenty of food, the bears do not hibernate, but in the winter, one of the Asian black bears in our zoo likes to curl up in the artificial cave to sleep. In winter, you can see lively bear children and big black bears sleeping.
In the winter, there is a lot of sleepiness
It is precisely because the zoo provides good environmental conditions for animals with hibernation habits, and gives different winter benefits for the habits of different animals, the animals living in the zoo do not worry about eating, afraid of heat in summer with air conditioning, afraid of cold and heating in winter, only need to be responsible for a healthy and happy life!
The animals of the small family do not hibernate, come to the zoo to see how the animals survive the winter!
