Species totals
This table presents a known species tally for the phyla represented in the Catalogue of Life. It compares the actual number of accepted and provisionally accepted species in the Catalogue of Life and the estimated number of species recognised by taxonomists at present; hover over the book icon to display the source used for the estimate. The last column displays the completeness (or coverage) of the Catalogue of Life, expressed as a percentage.
