Brotia is a genus of Southeast Asian freshwater snails, gastropod molluscs in the taxonomic family Pachychilidae.[3]

The generic name Brotia is apparently in honor of a Swiss malacologist Auguste Louis Brot (1821-1896).

Distribution of Brotia

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),[4] 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.
