A hundred-pound python appeared in Heilongjiang, and all the fish in the pond were eaten up. Where did this python come from?
As we all know, snakes are basically warm-blooded animals, which are often referred to as cold-blooded animals. They cannot consume their own energy to maintain body temperature like warm-blooded animals, so they are very sensitive to changes in ambient temperature. When the temperature drops below 15 degrees Celsius, it will go into hibernation. Due to the large temperature difference between the north and the south, compared with the south, the north is relatively cold most of the year, so snakes mainly live in the south. It stands to reason that there are no pythons in the north. If the pythons are forced to live in the northeast, they may not survive the winter due to the low ambient temperature. Snakes are basically warm and cold, there is a saying in rural areas, called "July wasps and August snakes", which roughly means that around July and August of the lunar calendar, it is the season when wasps and snakes frequently appear. Remind people to be careful not to be bitten by these poisons when going out. The seventh and eighth months of the lunar calendar are the hottest seasons of the year, which means that snakes will be more active in high temperatures. The study found that snakes became significantly active when the temperature was above 25 degrees Celsius; when the temperature exceeded 30 degrees Celsius, snakes became extremely active. However, a recent incident made everyone feel a little surprised. In Harbin, Heilongjiang, a giant python with a weight of hundreds of pounds appeared. Drained the fish pond and found a 100-pound python
Mr. Guo, a villager who lives in Shuangjing Village, Harbin, Heilongjiang Province, had a fish Tang, but recently he noticed something was wrong. According to Mr. Guo's description, the fish he put into the fish pond also weighed three or four thousand catties, but it seemed that there were no fish in the fish pond. Mr. Guo hurriedly got down a few cages to see, and sure enough, he didn't catch any fish, only some small crucian carp. It stands to reason that in a closed fish pond, the fish will not disappear for no reason, and I will come every ten or eight days to see how my fish look, and I have never seen any dead fish. To find out what was going on, Mr. Guo decided to drain the fish pond. The result was as expected. After the water was drained, there were really no fish in the fish pond. When the fish pond was about to bottom out, Mr. Guo once saw a huge black shadow swimming in the water, thinking it was a black fish, but the more he looked, the more wrong it became. Although there are black fish in his fish pond, they are only about ten pounds, and the black shadow is obviously very long. With doubt, Mr. Guo continued to pump water, thinking that he would catch this big guy after draining the water. But in the process of waiting, I suddenly noticed that there was a "rustling" sound in a grass on the dam. Then a huge python appeared in front of me, and I saw it was more than 4 meters long and weighed a hundred pounds. Now the truth is revealed. The 3,4,000 catties of fish that Mr. Guo put in are eaten up by it. After a "fight", with the efforts of Mr. Guo and the fish pond staff, he was finally caught. Realizing that this big python might be a national protected animal, Mr. Guo contacted the wildlife rescue station in time. After the staff arrived, they did see a huge python packed in a bag. After identification, this is a red-tailed boa, which originated in South America and other places, and there is no such species in my country. However, because they belong to the animals in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, and my country formally joined the Convention in 1981, the species in Appendix II are, in principle, managed as national second-level protected animals, so Although my country does not produce red-tailed anaconda, it is still a national second-class protected animal. What kind of snake is this?
The snakes that can be called anacondas are generally huge in size. The red-tailed anaconda in the anaconda snake family is medium in size, and the females are larger than the males. Adult female snakes are generally 2.1-3 meters long and 10-15 kilograms in weight, and male snakes are mostly 1.8-2.4 meters long. In captivity, they tend to grow larger, with a few large individuals reaching over 45 kg. In addition, the lifespan in captivity will also be longer, 20-30 years, and the highest record is 40 years, 3 months and 14 days. For example, the red-tailed boa weighing 100 kilograms found in Mr. Guo's fish pond is already at the level of a giant python, and the possibility of artificial breeding is very high. Red-tailed anacondas are large non-venomous snakes. There are 4 subspecies recognized internationally. They are widely bred in captivity because of their beautiful appearance and huge size. In the wild, the body color will vary according to the environment, most of which are mainly brown, gray or cream in color, with a brick red tail and beautiful markings on the body. Under captivity, more colors have been bred, such as albino, salmon color and so on. Red-tailed boas are mainly distributed in Central America, South America and some islands near the Caribbean Sea. Individuals in different regions have different personalities. Red-tailed anacondas living in Central America are irritable and easily provoked to attack people; red-tailed anacondas living in South America are docile, so most of the Colombian red-tailed anacondas are used as pet snakes on the market. They feed on birds, small and medium-sized mammals, and as their size increases, the size of their prey will also increase. Where did this boa constrictor come from?
Obviously, our country does not produce wild red-tailed anaconda, it is an exotic species, even in the warm and humid areas in the south, this kind of snake is not produced, so how does it appear in Heilongjiang Harbin Guojiayu? What about the pond? The answer is obvious, the probability of human release is extremely high. In the snake pet market, red-tailed anaconda is a relatively common species and is loved by many people. Many strange pets will buy them home through some means, and then raise them. For example, Liu Mou, a 28-year-old man from a community in Balizhuang, Beijing, once purchased 7 red-tailed boas, transformed his home into a "tropical rain forest", and raised these red-tailed boas. Some people keep strange pets, maybe not out of hobby, but out of curiosity, show off, etc., blindly follow the trend to buy. Or maybe it was a hobby at the beginning, and when the enthusiasm faded, I found that I was not suitable to keep this kind of pet, and the red-tailed boa was getting bigger and bigger and eating more and more, and the economy was a bit unbearable, so I put it They are abandoned into the wild. In reality, many alien species have flowed into my country through this route. Of course, there are also some "loving people" who will directly buy some snakes on the market and release them into the wild. The red-tailed boa has a relatively strong ability to adapt to the environment. Judging from the situation, the giant python that appeared in the Guojia fish pond is likely to be released artificially, and at least it was released into the wild before summer. It is possible to lurk beside the fish pond and eat so many fish. The harm of alien species invasion is a common topic. We do not oppose raising exotic pets, but they must be within the scope of the law and should not be discarded at will. Otherwise, it may bring considerable ecological disaster, and private release will cause serious consequences. , and will send itself in. Follow me and make a friend who understands animals.
