Atlantic surfclams and ocean quahogs are large-bodied clams that inhabit the continental shelf of the MidAtlantic. Their abundance is not dominant in the benthic community, and they have a patchy distribution. Sampling and survey strategies need to be carefully tailored to clams to prevent undersampling or possible bias in surveys. More information on this topic can be found here.
