Now, China's ecological environment has become very beautiful, the rivers have become clear, the forest on the mountain has become denser, the pollution has become less, the air has become fresher, people and other animals coexist in harmony, into the jungle, full of vibrant life, this is the "report card" achieved by the people of the whole country to actively plant trees and protect the environment.
This "report card" is not easy to come by, so in the later stage, we must continue to maintain and protect, do not let the ecological environment imbalance repeat itself, but some people do not buy the hard-won good environment, secretly mail back the living organisms from abroad, and they are not in China,Completely unaware of the ecological environment.
Mailing live animals from abroad has been found more than once, and recently there are live animals mailed to China from abroad, fortunately intercepted by China's customs, what is the animal? Let's take a look.
China's customs intercepted 29 live snails from abroad
Recently, when China's customs carried out X-ray inspection of the incoming parcels, it was found that there were suspected mollusks in the parcels, because the X-ray images showed that there were objects moving freely inside, and when the box was opened, it was found that there were 29 foreign snails hidden inside, each snail was as large as an egg, which obviously did not match the name of the item declaration.
These 29 foreign snails live, full, look like apples, after expert identification, they belong to the cover of the big snail, I believe that the Chinese people have not heard of this snail breed, this does not matter, because there is no cover big snail in Our country, the cover of the big snail belongs to the alien species, but now some people want it to flow into our country.
Cover the big snail
The large covered snail is a snail that likes to feed on the leaves, stems, buds, and fruits of grapes, perhaps because it looks a little like an apple, or perhaps someone sees it and thinks of the apple, and some people call it an apple snail, because it is compared to the people in Rome, the capital of Italy, and it is called the Roman snail, no matter how many it is called, it refers to the same animal.
The shell of the covered large snail looks thick and hard, the spiral part is shorter, and the body snail layer is expanded, the shell mouth is large, the mouth edge is simple and sharp, so it looks spherical, no wonder some people see it as an apple, the cover large snail is one of the largest land snails in Europe, the shell height is 5 cm, the shell width can reach 5.5 cm, and the size of an egg.
The most amazing thing is the amount of food that covers the big snail, can eat 5% of its own weight food at a time, and this is still a normal amount of food, I believe that no one can eat 5% of their own weight, if your weight is 150 pounds, then you have to eat 7.5 pounds of food at a time, which is obviously impossible to eat.
The covered large snail is distributed in many European countries, such as Switzerland, Germany, Denmark, Austria, France, Hungary, Belgium, Greece, etc., and long-term inhabits forests, vineyards, gardens or rivers at an altitude of 1600 to 2100 meters.
Covered large snails are more sensitive to the surrounding environment, changes in the surrounding environment can affect their food intake, the weather is too hot or too cold will affect their appetite, and even hunger strike, only when the natural environment becomes very suitable, they will eat in a big mouth.
Cover large snail non-toxic, belongs to edible snail, can be made into a delicacy, it is said that ancient Greeks and ancient Romans eat the tradition of cover large snails, in France, cover large snails are very popular, cooked is specially called "escargot", which shows that the French attach importance to it, because the cover of large snails is difficult to be farmed.
How harmful is a successful intrusion?
Although the covered snail can become a delicacy, the cover snail is regarded as a pest, because it feeds on more than 100 kinds of herbs, woody, vines, flowers, grapes, melons, vegetables, sweet potatoes, peanuts and other favorites, so the impact of the cover snail on local crops is still relatively serious.
The large snail with the cover will cause the leaves of the plant to be mutilated, the stems to be damaged, and even the young shoots of the plant will be eaten, resulting in no seedlings. What's more, the reproduction rate of the covered large snail is very fast, laying eggs in June and July every year, laying 40 to 65 eggs at a time, hatching out of the shell after three to four weeks, and maturing in two to five years.
Cover large snail life can reach up to 35 years, that is to say, a cover large snail can breed more than 1,000 offspring in a lifetime, the breeding speed is incredible, it is obvious that the successful invasion of the covered large snail is still quite harmful to agriculture, once it flows into the wild in China, it has a serious impact on China's ecosystem.
summary
Although the covered snail looks pretty, it is a good choice as a pet, and when the number is large, it can also be made into a rare delicacy, but the consequences of the invasion of the large snail are terrible, disturbing the ecosystem and destroying crops.
Therefore, those who want to have live animals should consider more about the ecological environment, and the situation that China's ecological environment is not easy to exchange, do not be ruined because of these small things.
