The shell that surprised me the most is the oyster shell. It looks more like a European Oyster Shell and I'm curious if anyone knows if this is possible. (I have read that they are farming them in Maine?)
But the big treasure of the day - is that large Operculum - it is the "door" to the Moon Snail - it covers it's aperture - the opening of the shell.
We also saw some Brant geese, Common Eider ducks and Sanderlings - sweet!
