Ok, if you already knew that than good for you. But I was watching the little garden pond this evening, just vegging out and meditating over the goldfish and bugs and such... when I spied a snail leave a plant stem, glide onto the bottom of the surface tension of the water, and glide about three full inches (at his standard snail's pace) to another stem. I Googled it out and sure enough....
