The living habits of snakes

Where do most ⒈ snakes live?

There are many kinds of snakes. Different species of snakes have different habitats. However, most snakes like to live at a suitable temperature and do not hide in their nests until nightfall, but there are also a few snakes that come out during the day, such as black snakes, Chinese water snakes, double-spotted brocade snakes, and so on.

What are the living habits of ⒉ snakes?

Snakes are variable temperature animals and are sensitive to the temperature of their surroundings. The outside temperature of 20: 30 ℃ is suitable for snakes to grow; when the temperature is about 25: 32 ℃, the nesting activity is more frequent; when the temperature drops to 20: 13 ℃, the snake will instinctively look for a warm place; above 33 ℃, it will look for a shady place or climb into a pool or ditch to soak in the cool. On sunny days in early spring, when the temperature rises to more than 18 ℃, snakes like to come out to bask in the sun at noon; after heavy rain in summer, especially at night, most of them come out to get some air.

At other times, such as snakes that come out "abnormal" during the day, most of them are weak or sick snakes, which should be isolated and treated as soon as possible. But there are exceptions, that is, a few healthy male snakes also like to move out of their nests during the day. Healthy snakes and sick snakes are easy to distinguish from each other in appearance.

Why do ⒊ snakes have the habit of hibernating?

Snakes are relatively primitive cold-blooded animals, which have no sweat glands and can not regulate their own body temperature, which varies with the temperature of the habitat. When the ambient temperature of the outside world decreases, the metabolism of the snake decreases and the amount of activity decreases significantly. So that do not eat, do not drink, do not move, in a lethargic state, in the form of "hibernation" to spend the long winter. This is also a natural genetic phenomenon that snakes have inherited for a long time or a primitive instinctive behavior to resist bad weather.

Snakes in hot summer, when the temperature rises above 32 ℃, snakes can not stand the persistent high temperature, will also enter a short "summer dormancy" stage. The time varies from north to south, depending on the local temperature. Once the snake enters the "summer hibernation", like the "hibernating" snake, it neither eats nor shed its skin, and adopts a very negative and limited way of nutrition supply to avoid the hot summer heat.

Is the hibernation habit of ⒋ snakes broken?

The hibernation of snakes (summer hibernation), but it must be reliably guaranteed by corresponding conditions, such as the state's advanced laboratory or the snake pavilion in a large zoo. General farmers are not suitable to break the "hibernation" breeding snakes, if that is to create conditions to break the "hibernation", especially the breeding quantity is relatively small, it will not be cost-effective.

If you want to solve the snake's "summer dormancy" is much easier, before the advent of the annual summer, you should plant flowers in time to recommend and build a melon shed. But sometimes it will be satisfactory, and the best way is to install a sunshade net. During the operation, only a small part of the snake farm can be covered, and the whole snake farm must not be covered, otherwise the fence will be too high and the cover will be too tight, which will directly affect the air convection between the snake farm and the snake nest. Especially in the midsummer plum rain season, if the moisture can not be released in time, it will cause excessive humidity in the snake farm or snake nest, and seriously will cause the mildew spot disease of the snake. Therefore, we must make rational use of the sunshade net to ensure that snakes do not have "summer dormancy" in summer, so as to achieve the goal of gaining weight and not losing weight.

Do all ⒌ snakes live in the same environment?

In the process of long-term reproduction and evolution, snakes have formed different habitat habits in order to adapt to the changes of external living conditions, such as small cracks in rocks, as large as stone caves, graves and tree caves. The first prerequisite for choosing a habitat is that the habitat must have a suitable temperature, not far from the water, good concealment, and a rich source of food nearby, such as frogs, rodents, birds, insects, and so on. Due to the different types of snakes, the specific habitat environment is also very different, which can be divided into five types: ground life, arboreal life, aquatic life, cave life and sea life.

⑴ ground-living snakes: most snakes belong to the ground-living category. This type of snake is characterized by broad belly scales and rapid and agile movement on the ground. Such as the five-step snake, the iron head, the purple sand snake, the eye king snake, the Liwen snake, the bamboo leaf green, the white-headed viper, the king golden snake and so on. Agkistrodon halys, vipers, cobras, golden ring snakes, silver ring snakes, white-lipped bamboo leaf green, yellow ridge wandering snakes, black mildew brocade snakes, brown and black brocade snakes, black snakes, red chain snakes and so on live in plain and hilly areas. Sand pythons and flower snakes mostly live in deserts and barren cliffs.

⑵ arboreal snakes: the main characteristics of arboreal snakes are: slender body, slender tail, good at winding and climbing, large eyes, relatively developed vision, broad abdominal scales and obvious lateral edges on both sides. They spend most of their time inhabiting trees, shrubs, branches or branches, such as green snakes, green snakes, golden snakes, flower forest snakes, twisted forest snakes, etc. Bamboo leaf green and soldering iron, red chain snake also often climb on the trees, but not as freely as the former. "Snake Island" Agkistrodon halys also belongs to arboreal life.

⑶ aquatic snakes: aquatic snakes that spend most of their time or all the year round active and foraging in creek ditches, rice fields, ponds, reservoir areas, etc., characterized by a thick and short size, a sudden thinning of the tail from the cloacal anal cavity, similar to the tail of a venomous snake, underdeveloped venomous scales, and nostrils located at the rostral spine. This kind of snake includes Chinese water snake, fishing snake, lead water snake, water red chain and so on.

The snakes living in caves in ⑷ are mostly primitive and low-grade small and medium-sized snakes, which are characterized by small head, small mouth, short tail and underdeveloped eyes and abdominal scales. The rule of activity is to climb to the ground at night or in dark weather, such as flashing scale snake and blind snake.

⑸ snakes that live in the sea. The most important feature of this kind of snake is that it lives in the ocean all its life, its tail evolves into a lateral flat shape, the nostrils are born on the back of the kiss, the torso is slightly flattened, and the abdominal scales are underdeveloped or even completely degraded. Sea snakes are all venomous snakes. Such as flat-tailed sea snake, long-kissed sea snake, green ring sea snake, flat-necked sea snake and so on.

How do ⒍ sea snakes expel salt from their bodies?

The salt content of sea water is more than 3%, and sea snakes can discharge a large amount of salt into their bellies because they have salt glands that land snakes do not have. Its salt gland is born under the tongue of the sea snake, that is, the posterior sublingual gland of the lower jaw. it has many ducts that communicate to the oral tongue sheath, and the excess salt flows into the tongue sheath in the form of secretion through the salt gland, and is carried out at any time when the sea snake sticks out its tongue. in this way, the excess salt in the sea snake is excreted from the body.
