What is this?

Can anybody help me identify this?

Limpit

That's probably a chiton. If it's a limpet it has a malformed shell.

Pull it out from under the sand and get a photo of the shell. It's likely a chiton, but it's hard to ID anything looking at the underside.

+1 Chiton. I have several.

Hmm I guess I never took a good look at the underside of my chitons. It does look like a chiton

I agree. And I can't say I've ever seen a chiton curve like the one in the pic. They may, but I've never seen it. They do have a segmented shell, so it's entirely possible, but every one I've seen is a very straight oval shape.
