Zimbabwe Absurdity

This snail was on my rowing machine this morning. I didn’t recognize it as a snail until it started to move. I have never seen a yellow, transparent snail before. I am not sure what type of snail it is, I don’t have a book on snails so if anyone else has an idea of what it is (is this the immature form of something?) I would like to know. I moved it onto a rosebush that had sunlight on it for a better photo. This was the only one of about 15 that was technically good. I did prefer the composition of another but it was not totally in focus. There is a price to pay using a compact camera – depth of focus is very difficult to control.
