Snuffbox (Epioblasma triquetra)

The snuffbox is a small freshwater mussel with unique "dripping paint" markings on its shell. It inhabits riffle areas in small to medium-sized rivers and streams where it is often found deeply buried below the surface. Its distribution has been significantly reduced throughout its range, and most populations have become small and isolated from one another. In Canada, the snuffbox was historically known from several watersheds in southern Ontario, but is now restricted to the middle and lower reaches of the East Sydenham River.
