What a pretty snail. I keep finding the most interesting creatures around our house. This one was in my driveway while I was unloading groceries and I could have nearly stepped on it! It is about 2 inches long fully extended. Check out this diagram of snail anatomy - fascinating! Not being much of a biologist, I'd never given much thought to the subject. I do have a small collection of tiny empty shells, gathered mostly from the tennis courts where we used to live. (click photos to enlarge)
I took a bit of video as well... it let me get so close and I was mesmerized by the slow and graceful movements of this gastropod.
