Catalogue of Life

The Catalogue of Life (COL) is the most complete authoritative list of the world’s species, maintained by hundreds of global taxonomists. As a global consortium, we aim to address the needs of researchers, policy-makers, environmental managers and the wider public for a consistent and up-to-date listing of all the world’s known species. We are happy to announce that we have just published the COL Checklist 2022 online!

The COL Checklist 2022 contains well over 2 million accepted species. More than 1.9 million are living species, and the rest are extinct. A large community of taxonomists, over 500 experts globally, representing 165 data sources is underpinning this global species list. Annual releases have long term support and will not be removed, so they continue to be accessible via the API and website of ChecklistBank .
