Did you know that snails have thousands of teeth?

Snails pose no danger to humans because of their small size, but plants may have to worry about seeing a slowly approaching mollusk.

Although not threatening in appearance, friendly invertebrates are among the animals with the most teeth in their mouths. Like snails and other mollusks, snails have between 2, 000 and 15, 000 teeth.

Fortunately, a snail's smile is different from humans, after all, it would be pretty scary to see a human mouth with more than two thousand teeth. Mollusks have microdeeth that are not meant to bite or catch prey, but to scrape surfaces or tear food. NPR people even managed to capture audio from a chewing snail. As expected, the bites are very slow.

The microdeeth are made of chitin, the same compound that forms the exoskeleton of some insects, and are mostly present in the radula, an organ that looks like the human tongue.

That is, just like the Alien Xenomorph, snails have teeth on their tongue, but they are used for food, not eradication of the human race.

With the microdeeth present in the radula, mollusks can scrape food from stones, walls, walls or even other living things. The composition of the snail's mouth also allows animals to tear plants into small filaments, which facilitates tasting.

Snails usually change their microdeeth within four to six weeks, in a similar process to sharks and crocodiles. As a result, new rows of teeth grow and push the old ones forward, which makes the snail's smile look even more frightening.

To the delight of the most fearful, all of this happens microscopically. So just hope no mutations occur and the snails remain small, because if they grow up, watching a single bite of the clam will be a pretty scary experience.
