Snails are a type of aquatic or terrestrial molluscs that belong to a large category under the class Gastropods. The body of the snail is soft, boneless, and curled, with a calcium shell inside as a protective shell. Snails come in a variety of shapes and sizes and play a variety of roles in different environments.
Snails are a very ancient animal that appeared as early as about 500 million years ago. They are widely distributed in freshwater and marine environments around the world, and some species are adapted to life on land.
The snail is an omnivorous animal that feeds on algae, bacteria, plankton, etc. and moves in its own calcareous shell. In addition, due to the many species and rich and diverse forms of snails, they have become an important source of ornamental and edible products.
It should be noted that due to factors such as overfishing and water pollution, some snail populations are declining sharply and are even on the verge of extinction. Therefore, in order to protect these rare species, people need to take active measures to protect them.
