The slimy, silvery trail often seen behind snails and slugs is this substance. The substance comes out of the front of the snail and gels on contact with air. The snail can move on very sharp or pointed surfaces because the slime helps protect its soft underside. A snail can even crawl across a razorblade! Some snails have feet almost as tall as their shells.Snails have soft, unsegmented bodies with a hard shell for protection. The shell has one or more whorls to reduce the chance of shattering. Many snails have more than one whorl, such as the Cylindrical Whorl Snail, which has a body whorl as well as many suture whorls. It even has a tipped protoconch for extra protection. Snails also have a mantle under the shell to protect the internal organs from damage. The snail has two pairs of tentacles on its head. The longer pair is for seeing, while the shorter one the snail uses for smelling. Without these tentacles, the snail would be in danger every time it moved.Though snails do not all have the same anatomical, most have similar organs. A snail often has eyes, a mouth, a radula, a lung, a digestive gland, a stomach, a lung, a mantle, an intestine, a kidney, a foot, and a heart.-Deranged Hydralisk
