Animals that need to hibernate include snakes, frogs, black turtles, squirrels, wasps, hedgehogs, polar bears, earthworms, snails, bats, dormice, etc.
Snakes are also animals that need to hibernate, and all species of snakes will hibernate. When the ambient temperature is lower than 15°C, snakes will enter the hibernation state. Judging from this temperature, snakes generally begin hibernation in autumn.
When it is time to hibernate, the snake will segregate itself in the hole and sleep for several months without eating or drinking, motionless to maintain physical strength. However, snakes do not completely fall asleep during hibernation. In sunny weather, snakes will sometimes come out to bask in the sun and occasionally eat. When spring arrives, the snake wakes up, begins to go out to look for food, sheds its skin, and changes into new clothes for the new year.
Frogs are amphibians and cold animals. Their body temperature will be affected by the temperature. As the temperature gets colder, their body temperature will gradually decrease. When the temperature drops to a certain level, frogs will burrow into the soil and stay in a resting state to escape the severe cold.
Frogs hibernate for about the same amount of time as snakes. When the weather gets cold in late autumn, , Frogs begin hibernation by hibernating at the bottom of the water or in caves, and return to the water to grow when the weather warms up the following spring.
Black turtles are cold-blooded animals, and their survival is greatly affected by ambient temperature. From November to March of the following year, when the temperature drops below 10 degrees Celsius, the black turtle will stop eating and lie quietly in the mud at the bottom of the pond or in loose soil covered with straw to hibernate and enter the hibernation period.
When it comes to animals that need to hibernate, people’s first reaction may be squirrels. I have read in textbooks since I was a child that squirrels will prepare food in winter, seal the holes with grass, hold their long furry tails to keep warm, start hibernating, and wait until the weather warms up before coming out.
In fact, not all squirrels hibernate. Some species of squirrels still move around in winter, such as Ezo squirrels and North American red squirrels. If they are pet squirrels, they will not hibernate because of the warmth indoors.
Chipmunks, Ezo squirrels, and herb dogs hibernate in winter. They appear to be dead during hibernation. Their bodies are hard and cold, and their breathing and heartbeat are so weak that they are almost invisible. Moreover, some squirrels Hibernating for eternity will definitely lead to death.
Lizards living in cold areas will hibernate. Most lizards live in hot and sub-thermal zones. If the ambient temperature is lower than 20 degrees, they will basically die and hibernation will not exist. A small number of lizards that are naturally temperate can hibernate. You may want to spread more sand and gravel and collect dead grass leaves.It can be placed in a place where the indoor temperature is relatively stable (cannot be placed in a place where the air conditioner or heating is frequently turned on and the temperature changes drastically) and the environment is relatively quiet.
Wasps, also known as wasps or ants. Wasps are semi-hibernating insects and begin to hibernate in groups when the temperature drops to 5°C. The lower the temperature, the tighter the group. When the temperature is slightly higher, the group becomes loose. When the temperature is higher than 7°C, the group begins to break up. The survival rate of wasps after overwintering is mainly related to the quality of clumping.
Hedgehogs are heterotherms. Because they cannot safely regulate their body temperature to maintain it at a normal level, hedgehogs hibernate in winter. Hedgehogs begin to hibernate in late autumn and do not wake up until the following spring when the temperature warms to a certain level. And hedgehogs like to snore, just like people.
Polar bears travel much less in winter and may not eat for a long time. At this time, they look for shelter from the wind and lie down on the ground to sleep, with their breathing rates reduced and entering partial hibernation. Unlike the hibernation of snakes and other animals, the partial hibernation of polar bears is like sleeping but not sleeping. Once they encounter an anxious situation, they can wake up immediately and change their minds hastily. And polar bears don't eat or drink for a longer period of time, not all winter.
When the temperature is lower than about 20 degrees, earthworms will stop growing and start hibernation, because earthworms will die when the temperature is lower than zero. Earthworms will burrow deep into the ground in winter, where the temperature suits them. Earthworms hibernate at 0-5°C, and their best survival temperature is between 18-27°C. When the weather gets warm next spring, they will start moving again.
Snails generally live in relatively humid places, protected from direct sunlight among vegetation, and where no one will disturb them. Snails that live in cold areas will hibernate, and species that live in hot climates will also hibernate during the dry season. The mucus secreted during dormancy produces a calcium film to seal the shell mouth, and the whole body hides in the shell. When the temperature and humidity are suitable, they will hibernate. Get out and exercise.
Most of the places where bats hibernate are in caves. During hibernation, the metabolic capacity is reduced, breathing and heartbeat only repeat per minute, blood flow slows down, and the body temperature drops to the same as the ambient temperature, but during hibernation Not deep, it occasionally penetrates and eats during the hibernation period, and can immediately return to normal after waking up. Their growth potential is not high, and there is a phenomenon of "delayed fertilization", that is, fertilization does not occur during mating before hibernation. The sperm spends the winter in the female's reproductive tract. It is not until the female animal wakes up from hibernation in the following spring that the female animal is mated. Ovulation and fertilization begin, followed by pregnancy and birth.
The dormouse is the animal that hibernates the longest. It spends about 9 months in spring, late autumn and winter of the year. During hibernation, they cannot eat or breathe, their breathing almost stops, their bodies become rigid, and no sound from the outside can wake them up. Their general lifespan is usually about 5 years, of which 3/4 is spent in storage. Even if they are not hibernating in the summer, they still sleep all day long and do not come out until night.
Hibernating animals will find a place to hibernate in autumn.
