In fact, there are more than 1 billion colds in the United States every year, according to the National Institutes of Health. And those facts change as scientists learn more about how colds work. Some people swear by zinc as a means of shortening a cold's duration, but research on that subject has been spotty.
The hard clam (Mercenaria mercenaria), also known as a quahog (or quahaug), round clam, or hard-shell (or hard-shelled) clam, is an edible marine bivalve mollusk that is native to the eastern shores of North America and Central America, from Prince Edward Island to the Yucatan YucatÃ¡n. peninsulaonfusingly, the ocean quahog is a different species, Arctica islandica, which, although superficially similar in shape, is in a different family of bivalves: it is rounder than the hard clam, usually has black periostracum, and there is no pallial sinus in the interior of the shell.

The quahog (pronounced coe-hog) is a species of hard-shelled clam and the one we most commonly enjoy in our chowders and po boys. All those other names - from little neck on up - are this same species of clam and just refer to how large the clam has grown. Little Neck: The smallest size of clam, amounting to 7-10 clams per pound. Cherry Stone: A little larger, you'll get 6-10 cherry stone clams per pound. Top Neck: These are sometimes also labeled as count neck clams, and they equal roughly 4 clams per pound.
