More than 700 different species of snails are distributed across the streams, rivers, and lakes of North America. Freshwater snails are important components of aquatic ecosystems, and many species are excellent water-quality indicators. Approximately three-fourths of these freshwater snail species are threatened, endangered, or of conservation concern or are already thought to be extinct. This publication describes snail biology, ecology, and biodiversity and discusses the importance of aquatic conservation efforts.
