The Quahaug (Mercenaria mercenaria) has been the official state shell of Rhode Island since 1987. Native to the eastern shores of North America, quahaugs (or hard clams) are one of many unrelated bivalves people refer to simply as clams.
The word quahaug (or quahog) comes from the Narragansett word "poquauhock".
So now you now.
Anyone for chowdah?

But those clams in the picture are really too small to be true Rhode Island Quahaugs.
This is a quahaug!
