Freshwater mussels are very diverse in the Ohio River and its tributaries. Historically, they have had the highest diversity (most varieties in one area) in the world. The construction of dams, river dredging and pollution has caused many species to become extinct or endangered.
Mussels have some interesting common names. Here are nine mussels found in the Ohio River.
