So why are snails the animals with the most teeth in the world? A study shows that snails have a lot of teeth. If you look carefully, you will find a small hole in the middle of the snail's antenna. This little hole is the snail's mouth. It is very small, about the size of a needle tip. Scientists call it "tooth tongue". Snail's mouth has a rectangular tongue with numerous tiny and neat horny teeth. These teeth have at most 135 rows, and each row has about 105 teeth. In this way, the snail has more than ten thousand teeth. It has also been calculated that the number of teeth of snails is 26,500, which is unmatched by other creatures in the world. So what is the role of snail teeth? In fact, snails not only have many teeth, but also they are very sharp. If you put snails in a cardboard box, it won't be long before you find a hole in the box. At this time, the snail will crawl out. Snails eat leaves with these teeth. They can chew any kind of leaves and eat them. When a snail finds food, it secretes a saliva with the acidity of 4% sulfuric acid solution. This saliva softens the food first, and then the snail will tear it up bit by bit with its toothed tongue. Snails are protected by hard shells, and their saliva and teeth are also powerful offensive weapons. Snails have the characteristics of survival. As soon as the little snail hatches, it can eat with its own teeth. Snails eat a wide range of food, mainly vegetables, melon skin, as well as some leaves, stems, buds, flowers and so on. It seems that snails are not good for agriculture But snails themselves have high medicinal value.
