Which animals need to hibernate?

Hibernating animals include bears, snakes, squirrels, hedgehogs, etc., and they generally try to eat as much as possible in autumn to store fat for hibernation.

Different animals hibernate in different ways. The main manifestations are inactivity, slow heartbeat, drop in body temperature, falling into a state of lethargy, as well as moulting, carp wintering at the bottom of the river, some insects overwinter with eggs, and some animals hibernate.

Some animals that have hibernation habits, such as squirrels, will store a lot of food for themselves before hibernating.

What are the animals that hibernate? How do they prepare? It's time to hibernate and the animals store everything they eat in their own holes.

Animals to hibernate are: frogs, turtles, hedgehogs, polar bears, earthworms, snails, bats, dormice, etc.

1. Frogs. 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.

2. Earthworms. When the temperature drops below 20 degrees Celsius, earthworms stop growing and begin to hibernate because they die below freezing. Earthworms burrow deep into the ground in winter, and there is a temperature that suits them.

Earthworms hibernate at 0-5 and have an optimal survival temperature between 18-27. When it warms up the next spring, they will be active again.

3. Polar bears.

Polar bears go out much less in winter and can go without food for long periods of time, at which time they seek shelter from the wind and lie on the ground to sleep, and their respiratory rate decreases and they enter partial hibernation. The hibernation of different snakes and other animals, the partial hibernation of polar bears is like sleep but not sleep, and once it encounters an emergency, it can immediately wake up and deal with changes. And polar bears just don't eat or drink for a longer period of time, not for the whole winter.

4. Hedgehog. Hedgehogs are isotherms because they can't regulate their body temperature stably to keep it at the same level, so hedgehogs hibernate in winter. Hedgehogs begin to hibernate in late autumn and do not wake up until the following spring, when the temperature warms up to a certain extent.

And hedgehogs like to snore, similar to people.

5. Turtle. Turtles are ectotherms, and their lives are greatly affected by the ambient temperature. From November to March, when the temperature drops below 10 degrees Celsius, the turtle stops eating and lies still in the mud at the bottom of the pond or in the loose soil covered with straw to hibernate and enter the hibernation period.

There are many animals that hibernate, from the big ones, like polar bears and brown bears! All kinds of bears for it! The little ones have frogs, toads!

They tend to try to eat as much as possible before hibernation to make themselves fat. That is, let your body accumulate more energy and fat. In this way, when hibernating, it is not easy to cause death.

Bears, snakes, and frogs all hibernate. In general, they eat more fatty foods in the fall, and in the winter they are less active and sleep more.

They will eat well before hibernation and then sleep soundly. When I wake up, it's almost spring.

1. In winter, many animals will choose to hibernate to survive the long winter. They chose this method in order to reduce the rate of metabolism and keep themselves alive in the cold winter of food shortages. Hibernating animals do not sleep for a long time, their body temperature and metabolic rate will still periodically increase, and they will wake up every once in a while to maintain a normal physiological cycle before continuing to hibernate.

2. Snakes often hibernate in deep rock crevices or underground burrows with constant temperatures, and they always nest in groups in a cave to conserve heat. Chinese alligators usually dig a tunnel of several meters to tens of meters on the shore to survive the winter. Frogs, on the other hand, prefer to wrap themselves in a dried film of mucus to reduce water loss.

Hibernation reptiles are sensitive to temperature, and if the temperature rises briefly on a winter day, they will wake up and crawl out of their burrows.

3. As a homeothermic animal with thick fur and fat, bears are not afraid of the cold, as long as they ensure sufficient food, or store fat before hibernation, they can maintain normal activities throughout the winter.

Animals hibernate in a variety of ways, with small hedgehogs curling up, bats hanging upside down, and snakes hiberning en masse. There are also frogs, turtles, snails, and bears that all need to hibernate.

1. Handstand crunching: The bat's hibernation method is handstand crunching, it will find a safe nest, and then use its hind paws to climb the stone crevice, its head constricted downward, and thus begin a long hibernation journey. 2. Motionless:

Some animals hibernate by staying motionless, such as the tortoise, when the natural temperature drops below 15 degrees, the tortoise will gradually reduce its diet, and when it does not eat at all, it is time for its hibernation to begin. 3. Report group hibernation: Report group hibernation refers to hibernation together to warm up, such as snakes, snakes will report reunion together to spend time in hibernation to ensure that they can wake up in the spring of the next year.

4. Shrink into a ball: Like a hedgehog that will wrap itself tightly into a small thorn ball when it hibernates, wake up and adjust when it is hypothermic before going back to sleep.

1. Swan. Swans, like geese, have the habit of migrating south before winter comes, and after spending a relatively warm winter in the south, they slowly return to the north.

2. Bears. Adequate fat is the best guarantee for surviving the hibernation season, and bears eat non-stop until winter arrives, stocking up on fat for themselves to prepare for winter.

3. Lizards. 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.

4. Bats. Bats also need to hibernate by climbing the crevices of the rocks with their hind paws, and then curling together with their heads down to start their hibernation vacation.

5. Frogs. The skin of the frog is very smooth, and it does not regulate its body temperature, so in winter the frog will stay in the burrow and wait for the arrival of spring.
