MolluscaBase is a comprehensive online database dedicated to the taxonomy of molluscs, facilitating research and biodiversity studies since its inception in 2014. As the second-largest animal phylum globally, molluscs boast around 86,600 valid extant species, with estimates suggesting that up to 200,000 species may exist. The database is a vital contributor to global biodiversity initiatives like the Catalogue of Life and the Global Biodiversity Information Facility (GBIF), offering an extensive range of information on molluscan species.

MolluscaBase provides detailed taxonomic data, including accepted names, classifications, authorship, synonyms, distribution, and stratigraphy for both extant and fossil species. It continuously updates its content based on the latest literature, ensuring accuracy and reliability. Notable projects integrated into MolluscaBase have significantly enriched its dataset, incorporating over 400,000 names. This invaluable resource supports researchers, educators, and conservationists, making it a cornerstone for those studying molluscan biodiversity and taxonomy worldwide.
