Why is the shell lang, whose life is so tenacious, also on the verge of extinction?

The living environment has deteriorated. There are very few places where they live, and the changes in their living environment make it difficult for them to adapt, so they are on the verge of extinction.

Because the living environment of the shell is shrinking, and the number is decreasing, it is also on the verge of extinction.

Because it is a pest that everyone fights, it is endangered because everyone hunts it in large quantities.

This may be related to changes in the environment, as well as climate changes, especially some extreme weather such as drought, which has a great impact on them, and people often use herbicides, insecticides and other chemicals, if these drugs remain in the feces, it will cause the reproduction ability of these insects to be weakened and will be less and less.

The feces shell lang feeds on animal feces, and generally has a strong ability to survive, but even this creature cannot survive, indicating that the animal feces have been greatly polluted, indicating that the environment has been further deteriorated.

In nature, there are all kinds of insects with strange names, and one of them is the dung shell. The scientific name of dung beetle is dung beetle, also known as dung pushing insect and dung coccidia, and its English name is dung beetle. There are more than 20,000 species in its family worldwide, spread across any land except the polar regions.

The body is dark brown, with a hard shell on the body surface, the antennae are gill lobes, and can feel the smell of various feces, and the three pairs of legs are strong and powerful, suitable for digging, and the membranous hindwings are usually contracted under the hard forewings, and only when flying. Swedish scientists have also discovered that it can use the phenomenon of moonlight polarization for localization, which is a major discovery in the study of animal positioning systems. Most dung shells feed on animal droppings.

They have a row of hard teeth on their heads, like a round palladium nail, which collects the dung together, and then rolls it forward with its feet to form a ball. The ball gets bigger and bigger, and in the end it can be bigger than the shell Lang's own body. This work sometimes requires a "husband and wife" to work together, one pulling in front and one pushing in the back, usually the female in front and the male in the back, with tacit cooperation.

There are also some scoundrels in the same kind of shells, who do not work themselves, and often snatch the dung balls that have been prepared by other kinds, and take possession of them, and there will often be a big war between the two sides. The prepared dung balls are pushed to a pre-dug cave for storage and slowly eaten. Females in the breeding stage lay their eggs directly in the middle of the dung ball, and the hatched larvae feed on the ready-made dung balls until they develop into adult dung shells
