Seashells of New Bedford Harbor

Seashells and other marine invertebrates found in the New Bedford harbor estuary, from Fort Phoenix State Park to Interstate 195. By no means a comprehensive list; merely what I found August, 2005, to April, 2009.
* Indicates that I’ve seen a living specimen in the harbor, as opposed to just a shell.
