During the Bonaire Estafette Expeditie the non-marine malacofauna was investigated. The investigation mainly focused on molluscs in natural habitats, but attention was also given to garden centers and botanical gardens as well known locations for exotic species. In total 31 (sub-) species of land snails and slugs and six species of freshwater snails were found. No freshwater bivalves were encountered. Twenty of these taxa were not reported from the island before. Based on these results an identification card of the land and freshwater molluscs of Bonaire was produced.
