Can Snails Bite?

Snails, those tiny creatures we often encounter in our gardens, have always been a subject of curiosity. We know they love munching on plants, but do they limit their appetite to just plants? Can these seemingly harmless creatures bite humans?

In this comprehensive article, we delve deep into the world of snails and explore the intriguing questions surrounding their biting behavior.

Can Snails Really Bite?

The answer is both surprising and intriguing: Yes, snails can bite! However, before you start worrying about snail-inflicted injuries, rest assured that their bites are harmless. Unlike other insects or animals, a snail’s bite feels no more than a minor scrape. Likely, you won’t even notice it when it happens.

A snail’s bite is not comparable to a venomous insect sting or a mammal’s bite. It feels more like a small knick or scrape, as snails cannot penetrate human skin or cause any bleeding. The reason behind snail bites is often their curiosity or hunger. They might mistake your hand for food and give it a gentle nip, but there’s nothing to worry about.

Understanding Snail Teeth

Wait, snails have teeth? Indeed, they do! While it may not be evident at first glance, all snails possess teeth. These teeth are small and composed of chitin, a tough and flexible material also found in the exoskeletons of insects.

However, snails don’t have the conventional teeth structure like mammals or humans. Instead, they have a specialized structure called the radula, which houses all their teeth in rows. The radula functions like a tongue, allowing snails to move their teeth around in their mouth. This unique adaptation gives them the ability to control and manipulate their teeth.

The number of teeth a snail has varied depending on the species, but in general, snails can have up to an astonishing 25,000 teeth. A typical garden snail, for example, boasts around 14,000 teeth. These teeth serve several purposes, including chewing food into smaller pieces and grinding it for digestion.

Moreover, snails continuously replace their teeth. As the old teeth wear out, they are pushed back, making way for new ones to emerge.

The Snail Bite Experience

Considering the sheer number of teeth they possess, one might wonder what it feels like to be bitten by a snail. As mentioned earlier, a snail bite is hardly noticeable. It won’t leave any visible teeth marks, and the sensation is akin to being scraped lightly by a toothbrush or licked by a cat.

The tiny teeth of a snail are not designed for inflicting harm, making their bites virtually harmless to humans. So, while a snail might nibble on your hand out of curiosity or confusion, you can rest assured that there’s no danger of a painful bite.

Reasons Behind Snail Biting Behavior

You might be wondering why snails resort to biting in the first place. After all, they primarily feed on plants and vegetation, so why do they occasionally bite humans?

  1. Curiosity and Hunger: Snails are curious creatures, and if they encounter something new or unfamiliar, they may give it a gentle bite to investigate. Moreover, if they are particularly hungry and your hand smells like something they would usually eat, they might mistake it for food and attempt a nibble.
  2. Protein Deficiency: Snails, like all living organisms, require a balanced diet. If a snail’s diet lacks sufficient protein, it may resort to biting to fulfill its nutritional needs. In such cases, it might try to extract some protein from your hand, which is a rare occurrence but not unheard of.
  3. Competition for Food: In cases of scarcity, snails may become aggressive towards one another, leading to biting behavior. When food sources are limited, they may resort to biting to establish dominance and secure their share of sustenance.

Snail Bites and Human Health

Snail bites, as mentioned earlier, are generally harmless to humans. However, there is a potential health concern related to snails. Certain species of snails, like the cone snail, can carry dangerous parasites, including the rat lungworm.

The rat lungworm parasite is acquired by snails when they feed on rat droppings containing infectious larvae. Other animals that consume these infected snails can also become hosts to the parasite, leading to potential health issues. While it’s unlikely for a common garden snail to carry such dangerous parasites, it’s essential to be cautious when handling snails in the wild.


In conclusion, while snails do possess teeth and can technically bite, their bites are harmless and barely noticeable to humans. These small creatures are more interested in their plant-based diet than biting people. If you ever find yourself bitten by a snail, there’s no cause for concern. Just apply a soothing cream and continue enjoying the wonders of nature.

However, it’s essential to exercise caution when handling snails in the wild, as certain species may carry harmful parasites. Always wash your hands thoroughly after interacting with any wildlife to ensure your well-being.

So, the next time you spot a snail in your garden or during a nature walk, appreciate the fascinating creature for what it is—a harmless and intriguing member of the natural world.
