The snail is a terrestrial taxon of the mollusk phylum gastropod, which belongs to the group of invertebrates. The body is soft and usually protected by a spiral hard shell. The head has two pairs of antennae, the longer one for sensing the environment and the shorter one associated with smell and taste. The foot is muscular and moves slowly on various surfaces by secreting mucus. The shell is one of its distinctive features. The shape and color of the shell vary from type to type. It is not only a protective device for snails, but also helps them retain moisture and adapt to a dry environment. It is an omnivorous animal that feeds on the leaves, stems and fruits of plants, and some species also eat humus or small insects.

Snails are mollusks of the family Snails, with over 25000 known species worldwide. Snails have a soft body with a spiral shaped outer shell, and their body is divided into a head and feet; There are 2 pairs of antennae on the head, 1 pair of longer antennae on the back, and 1 pair of eyes at the top of the antennae. There are jaws and file shaped teeth in the mouth, which are used for chewing and chopping food; The abdomen and feet are flat and secrete mucus at the bottom, making it convenient for the feet to use muscle contractions to glide on different surfaces. Breathing occurs in tissues similar to lungs, and air enters through the inhalation port. Snails are named because they have two horn like antennae on their heads when crawling.

The garden snail belongs to the "Halix" snail genus, which is native to central western Europe such as France and England. It usually inhabits gardens or shrubs, hence it is called the "garden snail" or the scattered snail. There are dense and delicate engraved patterns, with multiple dark brown spiral shaped bands that block the yellow spots or stripes that intersect with them., Shells have 4.5 to 5 snail layers, with a shell height of 29 to 33 millimeters and a shell width of 32 to 38 millimeters. The shell surface has obvious threads and growth lines, and the spiral part is short. The embryonic snail layer is smooth, and the body snail layer is particularly enlarged, with extreme inclination in the forward direction.
