Welcome to the Catalogue of Life website! The gateway to our online database of the world's known species of animals, plants, fungi and micro-organisms.
There are two distinct versions of the Catalogue of Life: the Dynamic Checklist and the Annual Checklist. Choose the version most suited to your needs.
The Annual Checklist is a snapshot of the entire Catalogue of Life: a fixed imprint. If you quote an organism from this version, others will be able to turn to that same reference - at any point in the future. All editions of the Annual Checklist to date are available online, and deposited in libraries around the world. Partner programmes, that link online to the Catalogue of Life, will reference the Annual Checklist.
Global Biodiversity Information Facility (GBIF) enables free and open access to biodiversity data online.
