Corbicula fluminea
Asian Clam
Asiatic Clam
Not native to Florida
Native to eastern Asia from Russia to Thailand and on the African continent, these clams are invasive in North America and now common throughout almost all of Florida. Asian clams have spread throughout the southeast, and up the Mississippi and Ohio River valleys. They are also present in much of southern California and Arizona, areas of the Pacific northwest and other scattered locations thoughout the United States.
Shells are yellow to brown, up to 5 cm (2 in.) long, and have ridges spaced wider apart than most other bivalves. The interior has a purplish tint.
The clam shells pictured here were along the rocky shore on the south side of Jackson Creek Island in Dale Hollow Lake, Tennessee. Live clams were in the shallow pass between the island and the mainland.
