Oysters are a family of bivalve mollusks like the clam, mussel and scallop. This means they have two half shells connected by a hinge that allows the oyster to open and close its shell. Oysters are native to many of the world's oceans and bays. Oysters are a very popular sea food. Oysters are also harvested by people for their pearls. Unfortunately, many of the world's oyster reefs have been destroyed by overfishing and coastal development. Due to the massive loss of oyster reefs, many states have oyster restoration projects in an attempt to revive the oyster population. Play the following videos to learn more about the oyster.
