I'd never seen these before. Saw 2 or 3 near one another. Cool! Update: After looking more at the distribution it doesn't seem likely that this is S. giganteus. Any other ideas?
There were many snails at this location, but suddenly I saw 7 of these all near one another. I'd never seen this type before (at least not these bright orange and green iridescent color). Are they Wavy Top Turban (Astraea undosa)? Color doesn't seem right, but I don't have any other guesses. I don't normally even try to ID snails because they are difficult, but I thought I'd try with these ones. They were about 2 inches across. Thanks!
There were some crabs in these pools that had a similar shape to striped shore crabs, but they were smaller and more olive green. What do you think?
No photo of this one. Just wanted to mark that they were there.
