Did you know that a snail’s anus is above its head?

For some reason, the urge to say this tends to appear when I’m eating with people. But I kid you not, an adult snail’s anus really is above its head.

At first, when the snail is young, its anus is at the other end of its body, like most animals, but as it grows older, its gut starts to twist, its body rotates so that the bottom end is above its head. Apparantly, its an evolutionary adaptation. With its anus with its mouth, the snail can hide most of its body in its shell for protection. The downside is that there’s a possibility that the snail will accidentally eat its own poop. But hey, a little poop’s a decent price for increased survival. Don’t you think?

Maybe not.
