Most species are found in rivers and streams, mainly fast-flowing, but two (''S. livida'' and ''S. tesselata''; sometimes in their own subgenus ''Navicella'') live in brackish coastal waters and the lower tidal section of rivers and streams. Their eggs are attached to hard surfaces such as stones. After hatching, many veligers avoid being swept away by the current by swimming close to the bottom, but it is speculated that some flow downstream into the sea only to return to freshwater later. The shell length of these snails is up to , but there are some size variations depending on the exact species.
