Slug ID?

[rw82]

Sorry, I know the picture sucks but I couldn't get it to focus any better. Anyway, the thing is shaped just like the pic shows. It is white in color and fairly flat in appearance (on both sides). Anyone have and ideas?
Thanks!

Does it have a shell on it back like a half clam? Does it move fast for a snail? My guess Stomatella snail. Good guy. Great algae eater.

no shell, seems to be moving really slow. It's maybe moved and inch over and hour or two. There does seem to be a slight ribbon on the other side.

Did you take a photo of the bottom of its foot???

 

[rw82]

Yes that was the only angle I could get at the time. The other side looks the same but with a faint ribbon. I can try to remove it and take a picture of the top side later today.

OK, if it just looks like it has a swelled area down the middle it's probably a polyclad flatworm. But...if you can get a pic of the top, I should be able to tell for sure.
