In winter, when do snakes also come out?

Many people believe that snakes are hibernation animals. So the snake will stay in the hole in the winter until the spring blossoms. But many people forget that snakes sense the seasons by temperature.

Therefore, if the temperature is high in winter, snakes will also come out to forage and replenish energy. Therefore, it is possible for snakes to come out in winter, but it is not very likely.

When snakes burrow in winter, the first thing is that the temperature is high. In winter, when the temperature is relatively high, the hibernating snake will wake up and come out to bask in the sun, after all, the snake is a cold-blooded animal and needs to absorb the sun's rays.

Only then do they have the physical strength to move and hunt, so snakes may also appear in winter. Secondly, predation is required. In winter, if the snake does not replenish enough energy to maintain its hibernation, it also needs to come out to hunt, especially when the temperature is better, the snake is likely to wake up and go out to hunt; Finally, the influence of other factors.

In winter, the snake is generally in a state of hibernation, but if its hibernation state is broken, the snake will also wake up, such as the environment in which the snake hibernates is destroyed, etc. <>

First, the temperature is high. The snake's hibernation is carried out according to the temperature, so if the temperature rises warmer in winter, the snake will also wake up, when the temperature rises, the snake will perceive, and come out to bask in the sun, absorb a little energy, and then the temperature will drop and then go to hibernation, but this possibility is very small. <>

2. Come out to hunt. Snakes need to replenish sufficient energy when hibernating, so that they can maintain the energy required in their bodies while hibernating. Therefore, snakes in winter will also come out because of insufficient supplementation, especially when the temperature is relatively high, and come out to replenish energy. <>

3. Hibernation is disturbed. If the snake's hibernation environment is disturbed, it will also come out, and when the snake hibernates, if its hibernation environment is destroyed, or is disturbed and affected by other factors, the snake will have to wake up and move its position.

Do you think snakes wake up in winter?

When food is scarce, although snakes hibernate in warm weather, they will still come out to forage for food when the weather is warm and food is insufficient.

Snakes live in relatively warm environments and will also go out, because snakes cannot distinguish the four seasons, and its so-called hibernation is determined by the weather temperature.

In the winter, if the snakes do not have enough reserves and do need food replenishment, they will also be dispatched.

The snake's most feared predator:

Badgers, ferrets, raccoons, hedgehogs, etc. among mammals.

Among the birds, eagles, eagles, vultures, hornbills, storks, etc.

Large toads and bullfrogs among amphibians also eat snakes, and there are many snakes that feed on other snakes such as the eyed king snake.

Snakes can be divided into three categories according to their diurnal activities: the first type is those that like to be active during the day, which is called diurnal snakes. The second type is afraid of bright light, prefers to be hidden during the day, and is active at night, which is called nocturnal snakes.

The third type is the snake that likes to be active in low light conditions (mostly at night and rainy daytime, and has strong cold tolerance), called morning and dusk snakes. Snake activity is much more affected by temperature than by light. For example, the diurnal cobra often appears at night in very hot summers; Morning and dusk pit vipers are often seen in low temperatures, when the sun is shining around noon, and are rarely active at night.

Generally speaking, the most suitable temperature for snake activity is between 20-30, and the optimal temperature for its activity is 10-35. More interestingly, snakes that live in the tropics are not only in winter"Hibernation", but also during the hot, dry summer months"Hibernation", as it is called in zoology"Summer hibernation"。When the hot and dry season arrives in the tropics, ponds and lakes may dry up due to prolonged periods of no rain, and snakes, like geckos, crocodiles, lungfish, and turtles in the grasslands, depend on conditions that become unfavorable.

In order to adapt to the environment so that they can continue to survive, they turn in"Underground", do not eat and do not move, enter"Summer hibernation"state in order to survive the hot and dry summer.

Snakes generally have nothing to fear except for predators. Snakes are reptiles that come out to hunt at dusk and when it rains. If there is anything that snakes are afraid of, it is low temperatures, so snakes choose to hibernate in winter.

Snakes do not have a specific time to live, snakes generally mate in early spring and summer, and lay eggs and hatch in summer, otherwise young snakes do not have enough time to accumulate enough fat to survive hibernation. Baby snakes born after September have a mortality rate of up to 50%.

Deep in the rainforests of South America, a snake species called the rainbow python is represented. To ease the molting, the rainbow python secretes a body oil with a strong odor that lubricates the old and new skins.

Snakes are ectotherms that change body temperature with air temperature, as snakes themselves do not have a well-developed thermoregulatory mechanism to produce and maintain a constant body temperature.

The optimal temperature for snake activity is 20 30, and the growth rate of snakes in this suitable range also increases with the temperature rises. For example, one study showed that at temperature, cobras gained more than one gram per month (with a greater difference among young snakes). But over 35 or so, they will be anorexic, sick, and 40 or 45 will die quickly.

Because snakes are cold-blooded, they can be found in warmer climates.

And when there are the most snakes, it should be in the mountains and forests and grasses after the rain in summer.

Because the rain often floods the snake's burrow, the snake will come out and move.

In summer, the sun is strong, and snakes like to be shaded and damp. Therefore, it usually haunts at night. During the day, snakes can also be found if the area is in good condition.

Snakes usually start to end hibernation around Qingming and come out to find food to replenish their energy after hibernation.

Snakes have the habit of hibernation, and in winter they sleep in their holes, sleeping for months, without eating or drinking, and maintaining their physical strength without moving. The weather is sunny and windy, and occasionally I come out to bask in the sun and sometimes eat. When the spring flowers bloom, the snake wakes up and begins to go out to forage for food, and takes off its original coat.

Snakes like to live in shady, damp, inaccessible, overgrown, wooded, with fir wood holes or piles of rocks, with firewood stacks and ancient ridge walls, and rich in bait, these are the places where they live, haunt and breed, and some snakes inhabit the water.

Snakes are a general term for reptiles with vestigial limbs, with a slender body, vestigial limbs, no movable eyelids, no ear holes, no limbs, no forelimb belts, and the surface of the body is covered with scales.

Snakes are ectotherms, with a lower body temperature than humans, also known as cold-blooded animals, when the ambient temperature is below 15, snakes will go into hibernation.

Generally during the Qingming period, that is, the period of rice planting in rural farmland, when I was a child, I studied in the countryside and walked at night, and at that time of the year, snakes were often seen on the roadside. Hibernation is in Bailu Bailu is the time for snakes to hibernate!

March 3rd. There's an old saying that goes like that. March 3 snake up the mountain.

There is an old saying: "On the third day of March, the snake comes out of the mountain." ”

Every spring, the snake will come out to mateMatched.

It should be summer, and there are more snakes in summer.

In the summer, it is the most, and in the spring, they all wake up.

The snake comes out of the hole on March 3 of the solar calendar or the third day of the third lunar month.

1. According to the data of snake science, the hibernation period of snakes in China generally enters hibernation before and after stinging, and the specific time is from November to April of the lunar calendar of the second year, but there are also those who start hibernation in early December and sting in early March of the following year.

2. The length of the snake's hibernation period also depends on the length and severity of the cold season, and the snake's hibernation period is extended with the increase of geographical latitude. The hibernation time of the snake varies according to different species, for example, the hibernation period of the Zhejiang soldering iron head is from late November to the beginning of April of the second year, while the hibernation period of the silver krait snake is from December to the beginning of March of the second year. The same species of snake hibernates at different times in different regions, such as the snake hibernates until April in Nanning, Guangxi, and from May in Hangzhou, Zhejiang.

3. The order of hibernation of snakes also has a lot to do with the species, gender, and age of snakes. The first to burrow into hibernation were non-venomous snakes, then venomous snakes; Compared with the same type of snake, the female snake is the first to burrow, followed by the male snake, and finally the young snake.

Fourth, the activity of snakes has a lot to do with the seasons. Generally speaking, the period from late spring to early winter is the period of activity of snakes, which is the period when snakes feed and reproduce. In winter, when temperatures are cool, snakes generally hibernate in dry, sunny burrows, tree cavities, or crevices in rocks.

Hibernation is an adaptation of snakes to low temperature conditions, and it is also a genetic trait that snakes have developed over a long period of time. Snakes do not hibernate during a period of sleep, but rather a state of dormancy caused directly by low temperatures.

Fifth, in the evolution of the whole vertebrate, snakes are relatively inferior animals, their tissue structure and functions are more primitive, and the metabolic level is also low, such as the heart only has a single ventricle, ** also lacks thermal insulation function, and there are no feathers or hairs derived from the epidermis like higher birds and mammals, and cannot form a thermothermal layer. Therefore, the body temperature of snakes is easily affected by the outside world, so they are called ectotherms or cold-blooded animals. When the temperature begins to cool in autumn and winter, the body temperature also drops, and the body's functions decrease.

When snakes are unable to maintain their body temperature at a certain height, they begin to look for suitable places to hide.

6. According to the measurement, snakes generally rarely eat when the temperature is 5, and they migrate to the vicinity of the wintering place; When the outside temperature drops to 8 6, the snake stops moving; When the temperature drops to 3 2, the snake falls into a state of paralysis; If the snake's body temperature drops below -2 or the outside temperature drops below -5, it will freeze to death.

Different species of snakes have different temperature requirements Generally speaking, snakes below 15 degrees Celsius will stop feeding and prepare to hibernate.

Generally in winter, when the temperature drops to seven to eight degrees Celsius, snakes begin to choose those hot and dry caves to hibernate. In the spring, when the temperature rises, the hibernation period of the snake ends.

It will wake up from mid-November to March of the following year.

When the temperature drops below about 13, snakes have to find various burrows underground to hibernate. Different species of snakes hibernate at slightly different temperatures due to different thickness of subcutaneous fat.

China's winter is the coldest region in the world at the same latitude, so snakes hibernate for the longest time (3 months in the south, 4 6 months in the north, and 7 months for pit vipers in Changbai Mountain), the deepest depth into the ground, and the southern boundary of hibernation is also the southernmost.

Snakes often hibernate in groups (to help maintain the temperature and humidity of the cave), and can sleep with all kinds of snakes.

When winter arrives and the temperature drops to 7-8, snakes begin to hibernate in caves, tree hollows and rock crevices in high dry areas. During hibernation, there are often dozens or hundreds of snakes of the same or different species in clusters. Why do snakes hibernate en masse?

Because snakes are cold-blooded animals, the temperature in their body varies with the temperature of their environment. In winter, when the outside temperature drops, so does the snake's body temperature. Therefore, snakes adopt hibernation to adapt to the low temperature.

During this period, the snake does not eat or move, and only relies on the consumption of the fat stored in the body before wintering to maintain the minimum needs of life activities. In such a harsh natural environment as winter, the mortality rate of snakes that live in scattered hibernation is as high as 1 3 to 1 2. If you hibernate in groups, you can increase the ambient temperature by 1-2 and reduce water loss.

This greatly reduces the level of energy expenditure in the body, reduces mortality, and also helps to increase the chances of male and female snakes mating after the sting in the following spring. Every year in April and May, after the snake stings, it begins to come out of the burrow, the first task is to find a mate to mate, the female snake's ** and the glands at the base of the tail can secrete a unique strong smell to attract the male snake to follow. Snakes are mostly oviparous, and a few are ovoviviparous.

From the beginning of summer to the beginning of winter, snakes feed and reproduce, and the three months of the year are the busiest time for snakes to feed, and the prey is very wide, including all kinds of vertebrates. Snakes don't chew when they eat, they just swallow their food. The snake's mouth can open wide and swallow food much larger than itself.

In the process of life, snakes also have the phenomenon of molting, and they have to shed their skin several times a year. The peel of the molten skin is called on traditional Chinese medicine"Snake molt"or"Longyi"It has the effect of dispelling rheumatism. There are more than 2 700 species of snakes in the world, of which 1 4 are venomous snakes.

The largest snake is the anaconda, which lives in South America and can reach more than 11 meters in length.

At about seven or eight degrees the snake begins to hibernate. The temperature at which various snakes hibernate is about the same.
