When do the animals in the mountains start hibernating?

Reptiles such as snakes, lizards, turtles, and other animals. Amphibians, such as frogs. Fish.

The habit of hibernation in animalsThe hibernation of animals is a wonderful phenomenon. In Canada, there are mountain rats that hibernate for up to half a year. When winter comes, they dig tunnels, burrow into burrows, and curl up in a ball.

Their breathing slowed down to almost ceaseless, their pulses became extremely weak, and their body temperature plummeted.

Squirrels sleep even deader. Someone once dug a hibernating squirrel out of a tree hole, and its head seemed to be broken, and no matter how much one shook it, it would never open its eyes, let alone move around. Put it on the table, and you can't even prick it with a needle.

It is only by heating it in a stove that it moves leisurely, and it takes a long time.

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 physiological 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 the timing of this hibernation cycle event.

Brown bear, black bear: tree hole Polar bear: dig a medium-depth pit in the snow, and lie down with the cub hibernation snake: In the hole.

Squirrels: Tree Holes Other rodents burrow in the ground to hibernate.

Frogs: Frogs hibernated hundreds of years ago were found in the ice, and they came out alive for a while. It seems that there are also in the tombs.

Turtle: In the shadows.

1. Turtle.

Hibernation is required. Increase and deepen the water body, set up stepping stones, remove or submerge the sundeck, reduce feeding on time and gradually, do not take the turtle out frequently to play, and do not use the back lamp, etc., just let the turtle stay quietly in the water and wait for hibernation.

2. Squirrels. When it comes to animals that need to hibernate, people's first reaction is probably squirrels. We grew up reading in textbooks that squirrels prepare food in the winter, seal their holes with hay, hold their long fluffy tails for warmth, start hibernation, and come out when the weather is warmer.

3. Snakes and snakes are also animals that need to hibernate, and all species of snakes will hibernate, and when the ambient temperature is lower than 15, snakes will enter a state of hibernation. At this temperature, snakes generally begin to hibernate in the fall.

4. 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.

5. Toad. Toads overwinter in swarms of sediment or on land in moist soils, and stop eating to maintain a minimum metabolism by storing glucose in the liver. Wait until the temperature rises to 10-20 the next day, and it will not end hibernation, which is one of the animals that hibernate for the longest time.

Explain in detail what animals hibernate in hibernation.

Hibernating animals can be roughly divided into two categories, one is amphibians and reptiles. Amphibians and reptiles such as frogs, snakes, and turtles are ectotherms. The other group is mammals. Mammals are further divided into two types: bear and squirrel.

Why do animals hibernate?

Some cold-tolerant animals have the habit of hibernation, after the frost falls every year, as the temperature drops, moles, burrowing rabbits, hedgehogs, etc. all hide in burrows and enter a dormant state that does not eat or move, at this time the animal's body temperature drops to the same temperature, the speed of breathing and heart rhythm slows down, and the metabolism drops to the lowest point. However, there is a difference between hot-blooded animals and cold-blooded animals, the rise and fall of body temperature of cold-blooded animals is determined by the external environment, while hot-blooded animals have purposefully controlled their body temperature, and they gradually lower their body temperature until they enter a state of hibernation. When they come out of hibernation, the heat-producing organs are fully mobilized to return their body temperature to their original levels within a few hours.

(1) Reptiles. Such as snakes, lizards, turtles and other animals.

2) Amphibians. Such as frogs.

3) Fish. 4) Molluscs. Such as snails, shellfish, etc.

5) And a considerable number of perennial insects also have hibernation habits.

6) Some small mammals also hibernate habits. Such as rodents, bats, badgers, martens, spiny moles, etc.

Rodentia. Chimbunk, European dormouse, golden hamster.

Pterodactyla bats.

Insectivorous hedgehog).

7) Among large mammals, only bears have hibernation habits. Such as black bears, brown bears, horse bears, polar white bears, etc.

There are many hibernating animals, here are a few common ones, frogs, snakes, turtles, turtles, etc.

There are three types of hibernation, the first is the hibernation of amphibians and reptiles such as snakes and frogs, and their 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 of body fluids below 0, their body temperature is maintained between 5.

The third type is bears, whose body temperature only drops by 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.

Hibernating mammals and human body structure, there is no difference between the two organs and tissues, but hibernating mammals can use special factors to control the neurohormonal system to regulate the metabolic state of organs, if this control of genetic factors can be found, it is not impossible for humans or other animals to hibernate in the future. In Taiwan, because of the warm weather, the hibernation time of animals should be very short, especially the hibernating animals in the zoo can still move freely in winter under the heat preservation and cold shelter facilities.

Therefore, to sum up, the hibernating animals of the class of mammals include polar squirrels, chinchillas, European dormice, golden hamsters of the order of rodents, bears of the order Carnivora, bats of the order Pterodactyl, hedgehogs of the order Hedgehogs, non-mammalian hibernating animals such as amphibian frogs and reptiles snakes and turtles, and species such as scorpions in the phylum Arthropoda are not found in winter.
