The snail moves about by means of a large, muscular structure called a foot. Waves of muscular contractions and expansions enable the snail to move forward. The snail secretes mucus from its skin, which lubricates the surface upon which it crawls. With its muscular foot and marvelous mucus, the snail can easily glide over many surfaces, including glass, on which it can move vertically and even upside-down. A snail can even move over a sharp razor blade without getting cut, thanks to the protective and slimy mucus.

Land snails breathe air, just like we humans do. Inside the lung, which is a region of tissue where gas exchange occurs, the oxygen is picked up by the blood, and carbon dioxide is emitted — again, just like human respiration. Under their shell, land snails have organs and systems just like humans do. In slugs, the organs are just behind the head region. Land snails have three main sets of organs for sensing the world around them, as shown by this diagram.

No one knows how well snails can see, but they definitely respond to light and are able to see where they are going as they move along, and their eyes do have a retina, lens, and optic nerve, just like our eyes. The lower tentacles are short and are used for smelling and tasting to help the snail find food and also avoid areas that could be potentially dangerous.

Nervous system : Land snails have various types of nerve cell endings, which arise from bipolar and multipolar cells in their epidermis, or skin. These enable the snail to feel a sense of touch and pain. Gastropods typically have a well-defined head with two or four sensory tentacles with eyes, and a ventral foot, which gives them their name Greek gaster, stomach, and pous, foot. The foremost division of the foot is called the propodium.

Its function is to push away sediment as the snail crawls. Land snails have a strong muscular foot; they use mucus to enable them to crawl over rough surfaces and to keep their soft bodies from drying out. Like other mollusks, land snails have a mantle, and they have one or two pairs of tentacles on their head.

The molluscs arose in the early Cambrian over million years ago , probably from ancestors resembling the Halikieriids. There are no known limbless species of mammal or bird, although partial limb-loss and reduction has occurred in several groups, including whales and dolphins, sirenians, kiwis, and the extinct moa and elephant birds. A slug has the same essential parts, except for the visceral hump or shell.

With the kind of sensory deprivation their sense of smell is extraordinary. They can apparently locate food from as far away as a few metres, which for an animal of their minuscule dimensions is quite the distance.
