What are the activity patterns of snakes? A detailed explanation
1. What are the activity patterns of non-venomous snakes?
Snakes' activities follow certain patterns. Since the distribution of snake species differs, the activity patterns of snakes also differ markedly. Taking Shandong Province as an example, the activity patterns of non-venomous snakes are roughly as follows: around mid-April (Gregorian calendar) each year, when the outside temperature slowly rises to 15-18°C, all kinds of snakes wake from hibernation and crawl one after another from their hibernation dens to the entrance of the den or to sunny spots to bask. After May, once the temperature has basically stabilized, the snakes leave their dens to move about, drink water, and seek mates to copulate. However, they are not very interested in the food provided, and only a very small number of snakes feed. Entering June, the weather in the north is already very hot, the feeding capacity of snakes increases markedly, and most enter the peak period of molting. July-August is the summer season and the plum rain season, and also the egg-laying period for snakes. In this season they often move about by the water's edge, and may even soak their entire bodies in the water with only the snake head exposed above the surface, while others coil up their bodies all day to rest in cool, shaded places, with activity mostly in the early morning or at night. In September-November, the temperature is moderate and more suited to the living habits of snakes, so the amount of activity and food intake increases markedly. Entering November, the weather gradually turns cool; in the first ten days, when the weather is warm, snakes can still be seen feeding or basking; once the last ten days arrive, the temperature drops markedly, and the snakes enter the early stage of hibernation. From December to early April of the following year is the hibernation period of snakes, lasting more than five months.
2. What are the activity patterns of venomous snakes?
The activity patterns of venomous snakes, like those of non-venomous snakes, also differ markedly due to differences in region and species. Some like to forage and be active during the day, such as the cobra and the king cobra; snake scientists call them diurnal snakes. Some prefer to hide by day and come out at night, such as the banded krait, the many-banded krait, the red-banded snake, and the turtle-shell snake, which fear strong light during the day and like to come out at night to move about and forage; these are called nocturnal snakes. Some like to be active under weak light and often come out in the early morning, at dusk, and on overcast or rainy days to move about and forage, such as the mamushi, the five-paced pit viper, the bamboo-leaf green pit viper, and the iron-head pit viper; these are called crepuscular snakes.
The specific activity times of venomous snakes are also linked to the activity times of the prey they hunt, and are not invariable. For example, the mamushi mostly preys on frogs and rodents around dusk; but the mamushi of "Snake Island" waits on sunny branches during the day to prey on birds; **the mamushi of western China also often preys during the day on @#@260@#@.
The activity patterns of venomous snakes also change with the seasons. Around mid-March each year (Awakening of Insects to Pure Brightness), venomous snakes slowly awaken from hibernation, but their reactions are sluggish and their movements slow, making it a good season for catching snakes in the wild. April-May (Pure Brightness to Grain Full), the activity capacity of venomous snakes gradually strengthens, and they begin to forage everywhere, but their crawling speed is still relatively slow; added to this, it is also the season of molting and mating, so it is also a good season for catching snakes. June (Grain Full to before midsummer), venomous snakes frequently go out to forage, drink water, and play in the water, entering a period of vigorous activity. July-August (Minor Heat to before End of Heat), the months with the highest temperatures of the year, most snakes completely leave their hibernation sites and move to waterside locations with good concealed conditions, mostly going out to move about and forage in the morning and evening or at night. September-October (White Dew to before Frost's Descent), venomous snakes enter a second season of frequent activity, and their food intake increases greatly. "When the autumn wind blows, the three snakes grow fat" refers to this season, when they store up nutrition in their bodies by preying heavily, laying the foundation for overwintering and resisting the cold in winter. After November (Frost's Descent), when the temperature drops below 13°C, venomous snakes successively enter their dens (holes) to hibernate, and do not awaken until the season of warm spring and blooming flowers the following year.
3. What are the activity patterns of rear-fanged venomous snakes?
Rear-fanged venomous snakes belong to the Colubridae family and are an intermediate type between venomous and non-venomous snakes. Such snakes are mostly small and medium-sized snakes, so in captive breeding the slightly larger red-banded snake and tiger-striped snake are mostly kept as the main breeding subjects.
Through breeding it has been found that the living patterns of these two snakes are also intermediate between those of venomous and non-venomous snakes. For example, the tiger-striped keelback, mostly after a heavy rain or a passing shower, turns out in full force and then preys heavily; some impatient ones, after seizing prey, swallow it forcefully into their mouths regardless of whether it is the head or not. The red-banded snake is a night-active snake, mostly leaving its den after 8 p.m. to move about and forage, and not returning to its original den until dawn the next day when the east brightens; this snake is seldom active during the day, and if any are found active outside the den during the day, they are mostly sick snakes and should be noted; but those that soak their entire bodies in water with only the head exposed to breathe are healthy snakes.
The Chinese water snake is mostly used as a feeder snake for artificial @#@246@#@. This snake loves to soak its body in water in summer, similar in appearance to the red-banded snake, except that several or dozens of them often tangle together; a considerable number of water snakes are also very good at climbing on tree trunks, branches, or small shrubs to cool off; this snake has strong cold resistance and hunger tolerance, and is suitable for breeding and then feeding to the king rat snake and large red-banded snakes; cobras and many-banded kraits also like to swallow it.
4. Will feeding change the activity patterns of snakes?
Although snakes look ugly and ferocious and give people a feeling of fear, they are actually very timid and are quite afraid of people. Therefore, when entering the enclosure to feed, move briskly as much as possible, do not make loud noises, and minimize the time spent lingering in the snake enclosure, so as to avoid abnormal activity caused by too many people entering or too long a stay, resulting in an unexpected "surplus" of the food provided, which then increases the workload the next morning and directly damages manpower and material resources.
5. When cleaning the pond and changing the water in the enclosure, will it change the activity patterns of snakes?
Because summer and autumn are the peak seasons of snake activity, water consumption is markedly greater than in spring, and frequent cleaning of the pond and changing of water will affect the snakes' activity patterns. In addition, when changing the water, the snakes in the water generally have to be scooped out or driven away, and the snakes' normal habitat environment is forcibly destroyed; some snakes may refuse food due to fright. It is suggested that after changing the water, do not feed for 2-3 days, so as to avoid wasting food.
6. When suddenly encountering severe weather, will it change the activity patterns of snakes?
"Knowing cold and warmth, distinguishing clear and overcast" is an instinctive response that snakes themselves possess, and also a relatively primitive adaptability by which snakes resist severe natural weather. From the regular abnormal reactions of snakes, people, through accumulated experience, can gain some understanding of weather changes and reasonably arrange farming and travel, which explains a great deal.
Most snakes not only know cold and fear heat, but also dislike wind and rain. When there is no wind or a level 1-2 breeze, they often leave their dens to move about; when there is a level 3-4 wind, they seldom leave their dens; when there is a level 5-6 wind, snakes almost do not leave their dens. According to breeding observations, snakes that are in the midst of activity, foraging, or molting, once they encounter a change in weather or sudden rain, immediately return to their dens or resting places, but aquatic snakes are the exception; after the severe weather passes, snakes resume their normal activity patterns.
7. During the peak mating season, will snakes change their activity patterns?
Most will not change; only a small number of unhealthy snakes, because their physical strength is severely insufficient, will prolong the mating time, and naturally they no longer follow their previous activity patterns. This is also a good method for distinguishing superior from inferior snakes. During the concentrated mating period in spring, their activity patterns are very easy to observe, because the grass and vegetation in the snake enclosure have not yet grown well, making the snake enclosure appear relatively open, and observation is much easier than in other seasons.
8. When snakes suddenly encounter enemies, what clever escape tricks do they have?
Usually people only know that snakes are timid and run when in danger, but snakes also have some little-known and interesting tricks.
(1) Thickening: when suddenly encountering an enemy they cannot deal with, some snakes can suddenly thicken and enlarge their bodies in a short time, and their appearance also becomes much more beautiful, and they can even turn their heads into an obvious triangle, making people mistake them for venomous snakes. In fact, this snake is called the ridge-nosed snake, also known as the "false mamushi," and is a typical non-venomous snake.
(2) Color change: when necessary, they can change their body color to roughly resemble the color of the surrounding environment, such as grass, branches, and rocks, forming protective coloration, making it hard for people (animals) to notice, and facilitating a surprise attack on the other party. Such snakes include the "Snake Island" mamushi, the bamboo-leaf green pit viper, and the emerald green snake.
(3) Venom spraying: highly venomous snakes that can spray venom include the king cobra, the cobra, and the five-paced pit viper. Their venom-spraying range can reach more than 2 m, and if sprayed into the other party's eyes, there is a risk of poisoning or blindness. These venomous snakes achieve the goal of subduing hostile animals in this way.
(4) Stink spraying: among non-venomous snakes, the large and fierce king rat snake, although it has the unique ability to swallow members of its own species and cobras alive, sometimes also uses the trick of spraying a foul odor to stun or drive away natural enemies in order to escape.
(5) Strange cries: this is a common tactic used by the king cobra and the cobra to repel enemies. When they encounter enemies, they can rapidly inflate the neck and raise more than 1/3 of the body upright, while emitting a "hiss, hiss, hiss" intimidating sound from the mouth; the patterns on the head and neck swell up as if wearing "glasses," and their appearance is incomparably fierce, so most natural enemies stop in their tracks.
(6) Playing dead: playing dead is a customary skill of timid snakes for escaping when encountering enemies. They can lie (coil) on the ground motionless, pretending to be dead to numb the other party, letting it nudge with its mouth, grab with its claws, or kick with its legs. Snakes that can play dead include the mamushi and the beauty rat snake, and after the enemy leaves they will "revive."
(7) Entering water: as the saying goes, "To escape disaster, a snake takes to the water." The vast majority of snakes have the ability to swim and dive, while those natural enemies that cannot swim, the "landlubbers," can only watch helplessly as the snake escapes through the water, such as the king rat snake.
(8) Sneak attack: the banded krait, the many-banded krait, and the red-banded snake have the habit of hiding the head beneath the coiled body, often giving the other party an impression of being honest and shy. But when the other party is off guard, they can suddenly flick out the head in a sneak attack and deliver a vicious bite, with a fairly high hit rate, making it impossible for enemies to guard against, such as the banded krait.
(9) Slipping away: the black-tailed racer, nicknamed "one slip black," never actively attacks people or livestock. Once it senses the slightest vibration on the ground, regardless of whether it is friend or foe, it will slip away and flee.
It is precisely because snakes have the above tricks that they can still tenaciously survive and reproduce under the tragic situation of "of ten people who see a snake, nine will strike it."
