I'd be interested in input on this. I've heard there is some dispute on whether we have other Spisula here (sayi??) and it seems to me the clams we get here are different from those we get in Menemsha on the Vineyard. Specifically, I never see the really large individuals with the black peristracum in these more local specimens. They tend to be smaller with these very clean shells. Just a thought. See additional photos of the dredge contents. Lots of Spisula shell.

No nifty white stripes, but seems offset like the ones with stripes... also on kelp with the others.
Commonly caught in scallop dredge. Numerous specimens today (~10)
Numerous specimens collected.
Collected 5-7 specimens via single tow (20 min) scallop dredge.
This species is often found inside empty clam shells; often right at the hinge. Collected via scallop dredge.
Several specimens attached to a Spisula shell and being encrusted by Didemnum. Collected by scallop dredge.
Bivalvia is a class of marine and freshwater molluscs with laterally compressed bodies enclosed by a shell in two hinged parts. Bivalves include clams, oysters, mussels, scallops, and numerous other families of shells. The majority are filter feeders and have no head or radula. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment on the seabed, where they are safe from predation. Others lie on the sea...
