How to Identify an Atlantic Surf Clam (Spisula solidissima)

Atlantic Surf Clams can be recognized by their large, triangular shells. Typically, these clams reach lengths between 7.9 inches and 8.9 inches. Their shells do not close completely, leaving a small gap. This species has a yellowish-white shell with rounded edges and concentric ridges that are easy to see when observing the surface.

When searching for Atlantic Surf Clams, they are often found in ocean environments, commonly in turbulent areas off the coast. The clams prefer depths ranging from 8 to 66 meters. The meat of the clam is another identifying feature; it tends to be white to light tan in color, adding to the distinctiveness of the species.

Characteristics
