Land mollusks travel by adhesive locomotion via muscular waves that propagate from tail to head. The snail mucus has an adapted flow behavior that allows transmittance of the muscular force while maintaining adhesion. When inactive, many mollusks of both marine and terrestrial species, use the secretion to stick to various surfaces. However, although it is so diluted that it can commonly act as a lubricant, it can also have strong adhesive properties. In their unique mating ritual, Limax maximus use a mucus thread to suspend themselves from elevated locations like tree branches. In Cornu aspersum, there are two types of secretion. One type is translucent and not adhesive, the kind that the snail leaves behind as it moves (the slime trail), and the other is similar but thicker, condensed, more viscous and elastic, which is used to adhere to various surfaces. Both are clearly differentiated by the type of proteins present in them. Slime Production A snail releases different kinds of mucus depending on the way it is stimulated. When the stimulation is normal, the slime is viscous (sticky) but if the snail is disturbed continuously or even violently, it releases clear foamy secretions. If the snail is sexually aroused the slime it releases is clear and viscous (sticky). In the case of Cornu aspersum, the discharge is composed of synthesized products from various types of secretory glands. These are all single-cell glands found in connective tissue and they secrete their products via pores that pass between the epidermal cells. They are of various shapes and usually have a long excretory duct. There are eight different types of secreting glands. Four of these different types secrete protein, calcium, pigments and lipids. Medical Uses Some of the characteristics of snail slime have shown to be useful in Chinese medicine. Traditional Chinese medicine has used slime in a variety of ways to treat a variety of illness and cosmetic issues. "For examples, snail powders can treat urinary obstruction by putting them above navel, can prevent nosebleed by blowing the powers into nostrils, can cure deaf by dropping snail powers/wine solution into the ears, can soothe toothache and laryngeal diseases. Furthermore the snail solution obtained by putting snails in water or wine can be used for curing hemorrhoids, boils, scrofulous, scars, and acne. It has also been used as skin creams for wrinkles and dry skin in cosmetics." The Chinese also have used
