Brotia is a genus of Southeast Asian freshwater snails, gastropod molluscs in the taxonomic family Pachychilidae.Köhler F. & Glaubrecht M. (2006). "A systematic revision of the Southeast Asian freshwater gastropod Brotia (Cerithioidea: Pachychilidae)". Malacologia 48: 159-251.
The generic name Brotia is apparently in honor of a Swiss malacologist Auguste Louis Brot (1821-1896).
Distribution Species of Brotia occur in freshwater habitats of Southeast Asia, ranging from Northern India in the west through to Sumatra in the east. This range includes India, Myanmar, Bangladesh, Thailand, Laos, Vietnam, China (1 species), Cambodia, Malaysia and Indonesia (Sumatra and Borneo only).
Biology Species are found predominantly in fast flowing, well oxygenated rivers, occasionally also in lakes. They are gonochoristic, and viviparous, retaining developing eggs and youngs in special brood pouch.
Species Species within the genus Brotia include:
