Odd shells in sandbed

[N.Sreefer]

I have the strangest shells in my sandbed that seemly come out of nowhere. Its solid inside I was thinking limpet at first. Any ideas?

Could it be a type of moon snail. Baby hitchhikers perhaps.

Looks like the little disk snails use to seal themselves in their shells.

The odd thing is its solid theres nothing organic in it. Its rounded and smooth on one side flat on the other with the iridescent spiral on it. And that's the third one I found today.

Nevermind, what I thought had the moon look was actually the underside. No sure but very interesting.

as stated, its the 'trap door' snails use to to protect themselves inside the shell. they come off when the snail dies... how many empty snail shells you have? each one of the things you find fits one of the empty shells perfectly

its called and Operculum

Its strange I only have periwinkles that have thin flat operculum, must've been snails that came on LR that I didn't notice. Probably ended up as a hogfish snack haha. Thanks!

I think it comes with the sand cause I had a lot of those too in my sandbed which was strange to me
