Periwinkle ID - Jeff D - 10-21-2015

This is the last of my troublesome shell/snail ID's from Cape Cod. Pic was taken in two feet of water with a rubble-strewn bottom. Pretty sure they are periwinkles, but various sources show them as being either common(littorea), rough(saxatilis) or yellow(obtusata)? I would gratefully accept a conclusion from an expert. Thx

Hi Jeff,
I'm definitely not an expert, but for me they look like common Littorina littorea. I have several species of Littorina here at home for comparison; L. obtusata and L. saxatilis look different, in my opinion.
Kind regards: wolf
