The shell fragments are often quite large and easily identifiable, but I can also identify quite small fragments, since I spend an awful lot of time looking at shells. Probably the most common fragments are from the clam Mercenaria mercenaria, but fragments of whelks (Busycon spp.) and moon snails (Polinices duplicatus*) are also very common ... The common whelk (Buccinum undatum) is an inhabitant of coastal areas of the northern Atlantic Ocean, as well on the eastern coast as on the western coast.The whelk mainly lives in cold water with a salt content of around 2 to 3 percent.
