Standard Disclaimer: The classification of the Animal Kingdom (Past & Present) has been, and is continuing to be, reworked by specialists and is further being complicated by the rules of Cladistics. I have no doubt that the names for many of the groupings (and indeed the groupings themselves) that I have used will draw criticism from somewhere. To help reduce the confusion I have tried to identify with common names, the creatures I have included in the groupings. I have not invented terms, but I am sure that not all of them reflect the latest classifications or nomenclature.
These are approximate numbers of known species, which I expect to update as newer, and/or better information comes to my attention . (My principal source reference and related links will follow the table.)
