MOLLUSKS

      Most mollusks are marine: clams, oysters, octopi, squid, mussels, oysters, scallops, etc.  A number of aquatic mollusks have adapted to fresh water as well—there are fresh water snails and clams, for example.  In the United States, the populations of a number of fresh water mollusks are decreasing because of the loss of wetlands.   A number of freshwater bivalves are threatened by the spread of the introduced zebra mussel which is outcompeting a number of native species.
