Botswana molluscs are represented by 63 native species (13 bivalves, 24 freshwater snails, 24 land snails and two slugs) and by four introduced species: Cornu aspersum, Lissachatina fulica, Physella acuta and Radix auricularia, which are potentially invasive and of economic concern. The majority of species occur in the regions of the Okavango Delta and the Chobe–Linyanti–Kwando river system along East Caprivi.
