It’s time to kick back, relax and slurp on that yummy half-shell called an oyster. Aug. 5 is National Oyster Day and that means we’re ready to celebrate the wonderful little mollusk in all its varieties.

Here are a few facts about oysters:

1.) There are over 100 species of oysters. Traditionally, they are named after the body of water or bay in which they are grown. It’s the body of water that gives them their distinct flavors.

2.) Oyster farming and cultivation can be traced back to Roman times in France and England.

3.) The largest oyster-producing body of water is the Chesapeake Bay.

Now that you’ve got a few facts under your belt, you’re ready to loosen that belt and consume some oysters. In an effort to find the nation's freshest oysters, we’ve come up with a list of the top 10 oyster festivals in the country. So get ready to shuck a few shells and celebrate American oysters.
