Not every animal in the world farts but coming on snails, do not fart. Moon snails, another kind of snail that lives in the sea, is also listed as a no. The property of a snail that everyone should know is that a snail’s bottom is right over its head. This is because snails are very different from other snails like creatures called mollusks. Because they are smashed into their protective shell, their body is twisted around to fit in their shell. Resulting, their bottom is just above and to the side of where their head comes out.
