   Aug 23, 2011 · Calculations of the number of species on Earth were based on the classification of currently valid species from the Catalogue of Life (www.sp2000.org, ) and the estimations for species in the ocean were based on The World's Register of Marine Species (www.marinespecies.org, ). The latter database is largely contained within the former.
