Species totals
This table presents a known species tally for the phyla represented in the Catalogue of Life. It compares the current numbers in the Catalogue of Life (both, accepted and provisionally accepted species) and the estimated numbers of species recognised by taxonomists at present. The last column displays the completeness of the Catalogue of Life.
