Two clams that were once listed as extinct have been rediscovered Scientists
that study mollusks found them in West Sosaria.
Richard Garriott, a marine biologist, found one of the clams. It is known as the
Moonglow mollusk. When Garriott saw the clam, he knew right away what he had
found. "It is my favorite clam," he said. He has found other clams once thought
extinct
Chuck Bueche wasn't so sure of what he found right away. "I didn't know that
I'd found an extinct clam at first," Bueche said. "It looked odd, and I knew that I
hadn't seen it before."
Sosaria has the most species of freshwater mollusks in the world. Forty years
ago, dams were built on the Maelstrom River. Some clams that lived in the river
lost their home when the water became still. Some animals could not live in the
dirty water. Clams keep water clean by acting as filters. They are also food to
birds, sea mammals and other sea life
