Snail
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.
