Information about animal hibernation, knowledge about animal hibernation

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.

Scientists have found that frogs also make their own antifreeze. In the laboratory, scientists freeze many frogs, 5 to 7 days later, and then slowly thaw them, and these frogs are still alive after thawing. After careful analysis and research, scientists have discovered a substance that people commonly use in antifreeze:

Glycerol. Similar to insects, in the spring, the substance is no longer found in the fluid of these frogs.

Bears, this animal needs to hibernate, in the summer and autumn, they eat a lot, turn it into fat and store it, and in the winter, when it is difficult to find something to eat, they hibernate for the winter.

Snakes, this animal needs to hibernate, in the summer and autumn, they eat a lot, digest slowly, and in the winter when it is difficult to find something to eat, they hibernate for the winter.

Frogs, this animal needs to hibernate, in the summer and autumn, they eat a lot of bugs, and in the winter when there are no bugs to eat, they hibernate for the winter.

Turtles, this animal needs to hibernate, in the summer and autumn, they eat a lot of food, and in the winter it is cold and they don't want to eat, so they hide in the sand to hibernate for the winter.

Hedgehogs, this animal needs to hibernate, in the summer and autumn, they eat a lot of food, and in the winter when there is nothing to eat, they circle into a ball and hibernate for the winter.

What are the hibernating animals? You must not think that polar bears actually hibernate, they live in the coldest Arctic, and many people wonder why they hibernate? In fact, there will be many, many more animals that hibernate, so let's take a look at them now.

For example: snakes, frogs, earthworms are the most common.

1. Snakes. 2. Black bears.

3. Polar bears.

4. Earthworms. 5. Frogs.

6. Toad. 7. Crocodile.

8. Hedgehog. 9. Turtle.

10. Squirrels.

To sum up, the hibernating animals of the mammals include polar squirrels, chinchillas, European dormice, golden hamsters of the rodent order, bears of the carnivorous order, locust bats of the pterocarpus order, and hedgehogs of the hedgehogs of the order Hedgehogs; Non-mammalian hibernating animals include amphibian frogs and reptiles snakes and tortoises.

Hibernation is a state in which an extreme but regulated decline in body temperature, metabolism, and other physiological activities is observed as an adaptation to reduced energy expenditure. This definition no longer includes seasonal or diurnal dormancy when ectothermic organisms react passively to a drop in ambient temperature.

Thus, true hibernation is limited to birds and mammals. 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 the timing of this hibernation cycle event.

There are three types of hibernation, the first is the hibernation of amphibians and reptiles such as snakes and frogs, whose body temperature is in harmony with the surrounding environment, and if the ambient temperature drops, the body temperature will drop and enter a state of hibernation, which cannot be adjusted.

The second type is squirrels and other animals whose body temperature is usually kept at a constant temperature, and when hibernating, their body temperature can be lowered to a temperature close to the surrounding environment, but in order to avoid freezing body fluids below 0, their body temperature is maintained at around 5.

The third type is bears, whose body temperature drops only a few degrees when hibernating, but can sleep without eating for a long time, which should be close to sleep and hibernation under strict classification.
