Catalogue of Life, [author list in alphabetical order] (ed.) (2021). Species 2000 & ITIS Catalogue of Life, 2021-05-07. Digital resource at www.catalogueoflife.org. Species 2000: Naturalis, Leiden, the Netherlands. ISSN 2405-8858.Description
The Catalogue of Life (CoL) is an assembly of expert-based global species checklists with the aim to build a comprehensive catalogue of all known species of organisms on Earth. Continuous progress is made towards completion, but for now, it probably includes just over 80% of the world's known species. The Catalogue of Life estimates 2.2M extant species on the planet recognised by taxonomists at present time. This means that for many groups it continues to be deficient, and users may notice that many species are still missing from the Catalogue. ### What's new in this edition (May 2021)? #### 64 checklists have been updated: * Alucitoidea (4th update) * ITIS (8th update since AC19).
