Molluscs are the second largest and most speciose invertebrate phylum after Arthropoda. There are around 7000 freshwater molluscs that play an important role in the ecosystem. Although many of these freshwater species are very restricted in their habitats, due to the increase in globalisation, trade, and transport, freshwater molluscs get introduced to new environments, becoming problematic to the native biodiversity and humans. Our compilation reveals 28 invasive freshwater molluscs globally, which reportedly cause serious problems to the native biodiversity, including economic loss, agriculture, and others. The major pathways of introduction for the freshwater molluscs are found to be accidental/ unintentional (e.g. as hitchhikers with macrophytes, ballast water, aquarium waste disposal) and pet trade. We obtained the distribution records for 28 species from global databases like Global Biodiversity Information Facility (GBIF), iNaturalist, and the published and grey literature. The species distribution modelling reveals Europe, South America, and Eastern North America as the most vulnerable regions. Niche dynamics analysis shows 14 species with lower and nine species with high niche overlap across the native and introduced ranges. Two species i.e. Corbicula fluminea and Physella acuta follow niche conservatism.
