This is a picture of a snail eating a giant piece of cucumber (relative to its own size, at least). Are snail mouths really that big? Is the cucumber actually in its mouth, or is it trying to climb over the cucumber? I'm not very good with snail anatomy. I do know that snails have both a penis and vagina though, so that's something. Something you don't forget after you hear in 6th grade science class. I got detention for asking if they can bang themselves even though that's a perfectly legitimate question. I lost my faith in the public school system that day.
Thanks to Amelie, who agrees that snail's eyes are definitely bigger than its stomach.
