This is by no means alarmist, because many years ago, experts from the CDC issued a voice to advise everyone that according to the pictures provided, experts judged that this snail is not a common harmless snail for humans and animals, but an African large snail, also known as a brown cloud agate snail.

Tip: Are snails pests or beneficial insects? Didn't you understand the problem? In fact, snails are not biologically taxonomic names, but a common name, generally referring to all species of gastropods (as well as aquatic snails). Whether it should be classified as a beneficial or a pest is still controversial. Because it has a certain medicinal value, high protein and low fat, some species can also be used as delicious, so it is still very valuable.
