Snails produce mucus to move more easily, protect themselves from dryness, and communicate with their fellow snails.
Mucus is a bit like the Swiss Army knife of snails. It allows them to move without damaging themselves on rough or sharp surfaces. It acts like a slippery mat that protects their soft body. Then, when it dries, this same substance forms a barrier that helps them avoid dehydration. When weather conditions become harsh or too dry, they simply seal their shell with dry slime and off they go for a safe nap. Mucus also protects their delicate bodies from infections or parasites due to its antiseptic properties. Finally, it sometimes even serves to deter predators, who generally prefer not to taste this unappetizing, slimy secretion.
The snail has small special glands located under its body that are responsible for the secretion of mucus. These glands, called mucous glands, function like mini-factories that continuously create this viscous liquid. When the snail moves, the muscles exert slight pressure on these glands, thereby releasing the slime as it advances. This mucus travels through tiny channels to the surface of the body, forming a slippery film. Depending on its needs, such as to protect itself or to climb somewhere, the snail effectively adjusts the amount of mucus secreted without even realizing it.
Snails adapt their mucus secretion according to ambient humidity: the drier it is, the more they slime to prevent their bodies from drying out. Conversely, in humid or rainy weather, they produce less mucus, as their movement is already facilitated. And what happens when it’s too cold or too hot? The snail also increases its slime production, sometimes forming a thick and protective mucus to isolate itself from extreme temperatures (estivation or hibernation). Even the quality of the soil changes the situation: on irregular or irritating surfaces, a snail automatically releases more mucus to protect its fragile foot.
The mucus of snails is quite a cocktail, primarily composed of glycoproteins, proteins mixed with sugars, which give it that viscous and sticky appearance. It also contains allantoin, a substance known for promoting cell regeneration and tissue repair (that's why it's found in our cosmetic products!). In addition, there is also collagen and elastin, responsible for the elasticity and flexibility of their slime. Not to mention glycolic acid, which exfoliates and hydrates the skin, explaining the beneficial effects (and trend) of creams based on snail slime. Finally, it all contains water, lots of water (about 90 to 99% depending on the species), to prevent the snail from drying out on the spot!
Snail slime may sound strange, but it has become a star ingredient in many cosmetic products (with moisturizers, anti-aging creams, and anti-acne products leading the way). With its repairing, moisturizing, and regenerating properties, it is very popular in cosmetics because it naturally contains beneficial substances such as allantoin, glycolic acid, collagen, and even elastin. Manufacturers also incorporate it into healing treatments to accelerate the healing of minor wounds or superficial burns, given its antibacterial and repairing effects. Finally, some cough syrups for dry coughs traditionally use snail slime due to its soothing and calming properties on throat irritations. Not very glamorous, but effective!
Snail slime naturally contains allantoin, a molecule that promotes skin healing and is used in cosmetics.
There is a species of snail called the 'cone snail,' whose venom contains toxins so powerful that they are being studied by scientists to develop pain relief medications.
Did you know that snails secrete different types of mucus depending on their activity? They produce a thin mucus for moving quickly (well, quickly for a snail!) and a thick, sticky mucus to adhere to surfaces when resting.
Some snails can produce a quantity of mucus that can reach up to 10 times their body weight in a single day!
Certainly! Here’s the translation: "Indeed, snail slime generally has natural antibacterial properties due to specific components such as peptides, certain enzymes, and mineral elements. These properties protect the snail from infections and are used in humans to prevent minor skin infections."
Sure! Here’s the translation: "No, the quantity and quality of mucus vary depending on the species, age, health condition of the snail, as well as environmental conditions. Some snails produce a more abundant or viscous mucus to better meet their specific needs."
In theory, snails have a limited reserve of mucus, but it is constantly replenished by specialized glands. However, extreme stress or harsh environmental conditions can temporarily reduce their ability to produce mucus in sufficient quantities.
Sure! Here is the translation: "Yes, the slime of terrestrial snails is primarily used for locomotion and protection against drought or predators. In marine snails, the mucus may contain more pronounced adhesive substances to withstand ocean currents and firmly attach the animal to marine surfaces."
Yes, snail mucus naturally contains allantoin and regenerating peptides that promote cell renewal and skin repair. This property is utilized in cosmetic products to reduce scars, wrinkles, and to soothe the skin.
