Corbicula fluminea is a species of freshwater clam native to eastern Asia which has become a successful invasive species throughout North America, South America, and Europe. Corbicula fluminea is commonly known in the west as the Asian clam or Asiatic clam.
Where are Asiatic clams found?
The Asiatic clam is native to Southeast Asia. It is also indigenous to parts of central and eastern Australia, Africa and the Mediterranean. It was first discovered in the United States in 1938, and it had found its way into most of the Mississippi River Basin by the 1970s.
How do clams reproduce?
Some species are hermaphrodites (which have both female and male reproductive systems). Male clams produce sperm and release it into the water, while females produce eggs that are retained internally. The sperm get drawn into the female bivalve through her siphons, and fertilization occurs.
