Identification Guide

Identifying the Atlantic Surf Clam involves observing its physical features and understanding its habitat. This guide highlights key identification traits, important characteristics, and comparisons to similar species.

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

Atlantic Surf Clams are notable for their size and shell shape. The shells are thick and strong, helping them survive their oceanic environment. Internally, the clam has both strap meat and tongue meat. Approximately two-thirds of the shucked weight comes from the strap meat while one-third comes from the tongue, often used to make dishes like fried clam strips.

The maximum size of this clam recorded is about 9 inches, but larger clams are unusual. Additionally, they have a relatively long lifespan, commonly living up to 20 years. The Atlantic Surf Clam thrives in salinities typical of ocean waters, usually avoiding areas with lower salinity levels.

Comparison To Similar Species

When comparing the Atlantic Surf Clam to similar bivalves, the Manila Clam (Ruditapes philippinarum) and Quahog (Mercenaria mercenaria) can be noted. The Manila Clam is generally smaller than the Atlantic Surf Clam and has a more oval-shaped shell. Quahogs are also smaller and have a rounded shell with distinct growth rings.

In terms of habitat, while both the Manila and Quahog clams may inhabit shallower waters, the Atlantic Surf Clam prefers deeper, more turbulent zones. Their shell shape and size are key identifiers, making the Atlantic Surf Clam easily distinguishable from these other species.

Distribution & Habitat

Atlantic surf clams are mainly found in the western Atlantic Ocean. They thrive in specific oceanic conditions that suit their growth and reproduction.
