The snail, commonly known as the dog snail, is a mollusk with shells, which is divided into two types: gray snail and homotypic snail. The snail has two pairs of antennae, of which the posterior antennae are relatively long, with black eyes at the apex, and the shell is medium-sized, the chitin is strong, oval, and the shell surface is yellowish brown or amber with dense growth lines and threads. The eggs are spherical, milky white and shiny, and the newly hatched young shells and shells are light brown.
Adult shellfish are similar to juvenile shellfish, and larvae eat very little.
The snail has a lot of teeth, and although its mouth is about the size of a needle, it has more than 26,000 teeth. The snail has a jagged tongue lined with 10,000 teeth in its mouth, and the snail eats leaves with these teeth, as well as thorny nettle leaves and holly leaves.
When a snail finds food, it secretes an acidic saliva equivalent to a 4% sulfuric acid solution to soften the outside of the food, and then tears the food up bit by bit with its toothy tongue and eats it. Therefore, while snails have a hard shell for protection, their saliva and teeth are the most powerful attack**.
Snails often live in a dark, damp, loose and humic environment, and prefer to burrow into loose humus soil to inhabit, lay eggs, regulate body humidity and absorb some nutrients.
