"Snail" means "cow" with a snail shell on its back. 2. In fact, although it is small, it has horns, great strength, and delicious meat, just like a cow. 3. France is the earliest place in the world to raise and eat snails. The recorded history alone can be traced back to the ancient Roman period. 4. Snails are eaten all over the world, especially in Western Europe and North America. There are more than 40,000 species of snails, ranging in size from small to large. The largest is the African snail, which can be up to 18×7cm and weigh 500 grams. 2Why do snails wait until it rains to come out?When the ground is wet or on rainy days in spring and summer, we often see snails on walls, ground, trees and grass. The main reason for this phenomenon is that snails need a lot of water to survive. Without water, snails will die. When the weather is fine, snails dare not come out to prevent the water from being dried up by the sun, but when it rains, snails will come out and move around. 3Why do snails climb walls?The mucus under the snail allows it to crawl on the wall. When a snail crawls, it relies on the ventral feet with horizontal folds on its abdomen, and it crawls very slowly. The ventral feet of a snail are wider in the front and narrower and pointed in the back. When it crawls, its ventral feet stick close to the object, and it relies on the expansion and contraction of its abdominal muscles to crawl forward, so that it can move forward slowly. When the snail crawls, its ventral feet glands continuously secrete a kind of mucus, which helps the snail crawl and increases its crawling speed. Therefore, wherever the snail crawls, it will leave a trail of mucus. After this mucus dries, it looks silvery white and very shiny. This is the snail's "footprint". |
